and IBdexi..,..,.,********. ,** .. ******.172

Historically speaking, some of the caddie flies of the south-

east were described at a relatively early date, about one hundred

years ago. At that time Francis Walker (1852 and 1860) of the British

museumm described twenty species from Georgia which were sent to him

by Abbot, and.this constituted the earliest large collection made in

the southeast. The investigation of caddie flies in the south stag*

n.ted for the next eighty-five years, for esxamle, fifteen years ago,

two out of three species collected in the state would hrve been un-

described. Since then much incidental work has been done by visiting

trichopterists and by entomologists rorlrkin in allied fields,

Caddis flies are f-irly abundant, but as compared with other

states, Florida shows a general paucity in the number of species

present; a rnucity most probably due to lpck of lmowledge rather than

a lack of ceddia flies. One hundred and eighty-four species have

been found in Illinois, a thoroughly studied state. On the other hand,

only sixty-three species have been found in Florida, thirty-eight of

which occur in Alachua County. Some day when the state has been in-

vestit-ted a ruood deal more thoroughly, this number will undoubtedly

be pre.tly increased.

In the Trichoptera, as in other orders of insects, our know-

lpdae of the immiture stages has leted far behind that of the adults.

The larvae of many species of caddir flies amoim to occur in the state

still are unknown or unesaocinted.


Betten (1934),. alduf (1939), and Ross (1944), have all care-

fully and fully summarized the extensive literature deocribinc and

deteilin- the life histories and habits of caddis fliee. For this

reason, no further discussion of this subject will be included here.

The current status of the knowledge of cr.dis flies in Florida

can be stated concisely. The species are very incompletely known;

cornm-r-tively few larvae have been associated with the adults. The

larvae of some genera have never been found and. much more collecting

of adults is needed. Georr"r.hic variation of the Trichopterap of the

1Thited States has never been investie ted thoroughly. Little col-

lecting has been done in northwestern Florida and many new records

plus undescribed species should be found there. Obviously, there is

amle room for far more study.

This researrch problem was specifically limited to the caddie

flies of Alachua County; however, as I had access to material collec-

ted in northwestern Florida I decided to extend the scope of the

.ntida; to include all th.t was known end all that I could find out

Pbout the ceddie flies of Florida. This additional material consisted

of caddie flies collected by Dr. Lewis Berner in 1939 and 1940, and

also spPcinens which were in the collections of the University of


7ttendin the study by the inclusion of this supplementary

nrterlpl -reatly broPdened the entire picture, but also, simultaneously,


complicated its for the oolleotions examined were sufficient to raise

a multitude of questions but were insufficient to answer may of them.

For eanry problem solved, two were discovered which ccvld not be ao-


This report is the result of an investigation earrr.c onm for

two yearc-----from Fcriary, 1950 to Februlry, 19r6-----in .- '..ch time

I colleotec appro!rnPtely 10,000 speciiens and examirne an ,'l1tieonal

eight lrTndred inrdivdirrle vhioh were collected by other.

The purpose of this investigation is to present (1) an

annotated liaf of the caddis flies found in Alachua County, (2) a

oheck list of the oaddia flioj of Florida, (3) keys for the identifi-

cation of the larvae and adults found in Florida, vnd (4) a biblio-

graphy which inolides all references to Florida ead'li fliec. In

Ohort, this investigetion has two Frir~ry rpirposes: to report Cn the

caddie flies of Alatohna County and to gather together all tha-i: is

Imown about the crodiv flies of Florida. As such this report mirj.t

well aorve as a foundation for a future study of the oanidii flios of


On the basis of the information gathered in this study, which

of necessity is very incomplete as collections from parts of Florida

other than Alaohua County are very spotty, the state of Floricn oan be

subdivided Into two areas hwv nG d3itinct caddsi fly faunara (1)

Iorthweteorn Florida, and (2) Peninsular Florida. Northwest-rn Florida


certainly has a fairly distinct fauna for many species of caddie flies

hrvinf northern effinities Pa& are found here which are not collected

in the Gainesville region. "The Apalachicola River draineTe has with-

out doubt been the main hirh::.y of ingress to Florida for the great

majority of animals which require flowing water or h-rdwood forests.

Ro ers (1933) found that the ecological conditions existing in the

Apalachicola drainage woould admirably explain the distribution of

many northern craneflies in Florida, Carr (1940) reports that the

most extensive invasion of Florida by the northern element is encoun-

tered in that portion of the panh-ndle which is drained by the Apala-

chicola River. Hubbell (1936t354) states that in this peculiar en-

vironment (the deep ravines of the Apalachicola region) a gre-t many

northern plants occur, evidently the remnants of a northern flora left

as relicts from Pleistocene times in these deep, moist, cool revines.

"It has elso been noted that many northern plants re-.ch their southern-

most limits in these rrvines and many typically southern plants inter-

nin'-l here with the northern species. Iot only is this true of plants,

but such has proved to be the case in the craneflies, the Odonata, the

Opilionids, the Orthoptera, the crayfish, the PrThibi:,ns, and the rep-

tiles." (nerner, 1950). Peninmnil-r Plorida has a number of endemic

species, but the majority of the fauna is composed of species having

a far riider reolra.nhlc range.

Oaddil flies are fairly nbundrnt in Florida --- they can easily

be found -- but they do not appear to be present in numbers as larre


as those occurring in many northern streams. I hnve never collected

caddie flies in the north or the west, but I have reed many descriptions

of the immense numbers of these insects which swarm in northern streams.

The rock dam near Poe Springs is the only locality in Alachua County

which apnropches these descriptions of northern abundance.

In the north caddie flies are an important link in the aquatic

food chain, for they convert small units of food into larger units,

and since they ere present in tremendous numbers, they are a group to

be reckoned with, Caddie flies constitute an important factor in the

diet of many northern fish.

This does not seem to be true in Florida. I do not believe

that caddie flies are abundant enough (except in certain scattered

localities) to be a major link in the aquatic food chain. Reid (1950)

found the number of caddis flies eaten by the Black Crappie, Pomoxli

nIorm-clntus, in Orange Lake was insignificant. William McLane

(personal communication) found the same condition to be true while

he was workln- with large-mouth bass in the St. Johnts River. Very

few caddie flies were found in the stomachs of the bass.

Caddie flies are important in Florida, however, as indicators

of stream pollution. Many stream forms of caddie flies have an ex-

tremnly low ecological tolerance and cannot withstand any stream pol-

lution. According to William Beck, Jr., of the Florida State Borrd

of Health (personal communication), Cheumatopsyohid larvae will

tolerate pollution of a minor degree while most other caddis flies

will not. Personal observation bears this outt for example, in the

summer of 1950 the East Branch of Hogtown Creek had a caddis fly

fauna composed almost entirely of Cheumatopsychid larvae, while the

West Branch had a more varied fauna. Many old, empty Leptooella

and Oeoetis cases were found in the East Branch showing that other

species had lived there. Since it is known that the East Branch

occasionally becomes polluted, it would seen likely that the oreek

was slightly polluted in the summer of 1950, and that only the

Cheumatopsychid larvae could withstand the pollution. Ross (1944)

corroborates these observations* He states that members of the

genus Cheumatopsyche can frequently succeed to some extent in streams

too polluted for almost any other caddie flies. Therefore, it appears

that caddis flies can be used to show compnrative pollution (1) if

a stream is unpolluted, there will be a varied caddie fly fauna present,

(2) if a stream is slightly polluted, only Cheumatopsychid Iyrvae will

be found, and (4) if a stream is highly polluted, no oaddis fly larvae

will be present.

Although this is the first systematic study of this group of

insects in the state, the Trichoptera of Florida, and ccpecially

Alachua County, were previously fairly well investigated. Caddie

flies were collected by Drs. Lewis Berner, J. Speed RoEers, Frank

Young and others, end vwre sent to authorities for i~Sntification.

V.-rioui ruthorities on caddis flies made quic': collecting trips

thro-,th'out the stte. Almost all of this has been incldent.!'l col*

lectlnr in scattered locations rather tha. thorou.-'h, s.ytem7tic,

faunal studieS. Furtherr.re, information on the caddis flies of

Florida was citttrred -- indceed much of it was unpublished -- and

has been inpcceesible to all but a spFC"lirit. For these reasons

this problem has been Turnued long the aforementioned lines; a

faunal study and a consolidation of knowledge.

This study could not have been completed without the help

of many individuals. I take great pleasure in acknowledging the

time and thought spent by these men and was greatly impressed by the

willingness with which this help was extended.

I especially wish to thank Dr, Lewis Perner for his guidance,

constructive criticism, and for the many specimens collected by him

in other parts of Florida, Dr. M{inter Testfall spent many hours

helping with the photography, Dr. Cornelius Betten sent a list of

all the caddie flies he had collected in Florida end a list of all

the oaddie flies recorded in the literature which were collected

in Florida. Dr. Herbert Rose of the Illinois Natural History Survey

sent me many of his reprints, gave advice and identified some

specimens. Dr. D. G1 Denning of the University of Wisconsin sent

a number of his reprints. Mr. Ellis Lanquist, Dr. J. Speed Rogers,

Dr. Frank Young, Mr* R. P. Trogdon, Dr. B A. Barrington, Mr. Jon

Herring and others too numerous to mention, collected specimens used

in this investigation. Mr. Bert Theuer helped greatly in the

preparation of the keys by drawing the heads of some larvae.

William Book, Jr., George N. 7Teld and William MoLane aided

by oantributing bits of essential information used in this study,

Last, but by no means least, I would like to thank all

those who contributed materially by offering criticism, advice

and suggestions.

Three different methods were used in collecting cpddin flies:

(1) the larvae and papae were collected from water, (2) the adults

vere collected at light, and (3) adults were collected during the

day by sweeePin vegetation overh-nr~ning in-ter or by ne-rchin- crevices

underneath bribes. Since no one method will yield a representr.tlve

collection of the area, a conrbin-tion of all three was used,

All ITearctic caddie fly lprvee rnd, .puae p rrea qu.tie, and

almost any type of ?qu-tie hl.bitat is a -otenltinl collecting site.

Stonor and pieces of :ootd were brought to the surface for examine-

tlon. Leaf-drlft, rouvtic vepet-tion, end debris vere du-ped in a

pile on shore, After drying for a few minutes, the lprv. e begin to

rovr and can easily be .rottec.. Some pupal and larval cases show a

high derTer of protective colorFtion tnd blend in well with their

surroundinns, but with practice these cases can be readily disttin*

Fron a quantitative point of view I found the best place to

collect larvae and nnrpe in Alachua County was in rpTida end riffles;

for example, the rock dam at Poe Sprin'!. The larvae are present in

this snot in tremen9ovs numbers. I also found nui.ntities of larvae

by exratinlnrg the lenf-,rift in some of the numerous, small, swiftly-

flowin,, urnpolluted streams scr.ttered thror-hort' the county; for

e2rample, ptrts of "o~to:n Creek. Larvae nr' be found in all conceiv-

able tyrnes of aquatic habitats, for there are records of immatures


being found in pitcher plants and the hollowed-out boles of tree

stumps that had collected a little pool of water,

Adults of most species of caddis flies will come to light on

warm, still nights, and I used this technique extensively. Specimens are

to be found on store vindons; pink neon lights especially attract these

inseots. TMhile some specimens can be found in town on store windows,

lighting on the shores of streams, lakes, oto* is essential. I have

had good results using a Coleman, single mantle, gasoline inltrn.

Caddis flies clinging to the lighting sheet can be collected by

holding a small, wide-mouth jar half full of 85" alcohol directly

beneath the insect and tapping directly above the insect w.ith the

forefinger. The startled caddie fly will leap backnanrds into the

open jar* Dipping an index finger in alcohol, scooping up the insect

rapidly but gently on the wet surface and then dipping it in the bottle

is a rapid method which I used for collecting iany small caddis flies

I have used an automatic light trap with success. The trap

was set in various places overlooking water and was periodically


In daylight collecting of adults, sweeping vegetation with

an insect net is a neo&ssity for some species are negatively photo-

tropic and cannot be caught at light. Resting places differ with

the species, but most eaddia flies prefer shaded, humid places. Vege-

tation overhanging water and crevices of tree trunks are favorite

resting places. These insects are very fast and agile, and swift


movemont i~ required to oaptura then,

Frequently the adults may be captured on sticks end vegei-

tion floating on the water. When floating vegetation is submerged,

trapped adults will quickly swim to the surface,


All cddfis flies, both immature and adult, were preserved in

85,' ethyl alcohol. One genus, ,Letocella, wao collected dry since

identific-tion in this genus depends lrrely on the p-ttern of hairs

on .the wrinrB. I eost specimencof this genus were killed in a cyanide

jar and were carefully pinned.

The genitalia were used to identify almost all species of

caddie flies. It was usually necessary to clear the genitalia to

see the dipgnontic characters. I have used the following clearing

procedureI The apical third of half of the abdomen was removed and

placed for five minutes in a hot five percent potassium hydroxide

solution heated in a water bath. It was then transferred to alcohol

and the viscera were gently squeeze out. The cleared gFnital cap-

sule and the cnecimen to.rhich it belongs were put in a small vial

rpnroximntely 74 by 4 mm. This vial was filled, stoppered with a

cotton plug and inverted in a ring neck 4 dram vial.

It was desirable to clear the entire body of the micro caddie

flies belonrnin: to the family Hydroptilidae. The Mbdomen was not

detached. The procedure used is the same as above except in this

case it was necessary to teat a slit in the base of the Pbdomen through

rhich the dissolved viscera was expelled.,


Two major methods were used to associate larval caddie flies

with their adult forms. The larvae or pupse were either reared in

cmes until the adult emerged, or the pup-e were dissected.

Laboratory Rearing

Reprinn caddis flies in the laboratory is a difficult pro-

cedure, for many species have a low ecoloLc-l tolerance, and n-tural

conditions mnist be clmulnted. Therefore, in trying to increase the

yield of reared adults, I developed a number of different rearing

methods: (1) a series of eight screen wire cages, each enclosing

a balanced, aereQted aquarium were used Both larvae and pupse were

kept in the nquaris. All the larvae died occoslon.lly some adults

emerged from the pupal case. Vhen caged together, the larvae are

cannibllttic, and the larvae that survive are usually killed by

the chaneI in their environment. Pupae, however, require nothing

to eat, and if the putp is mature, the pdult will emer~e within a

few days. Pupae of certain species are often rather scrarce, which,

since it is difficult to find enough individuals to nmrai certain that

re.nlts will be obtained, constitutes a. major icrAvwnt ce. (2) SCob-

terred rocks and vegetation covered with r.upne end Irrvr.e were taken

from their natural habitat and kept emoitened, but not submerged, in

large screen-wire cages. The enddis fly inn.atures were able to get


all the o-yp.en they needed by 5'eepinr them in contact with air r-ther

than water, The larvae died, but many pupae survived and .,ere re-red

to the Piut -tage. Micfel and Milliron (1939) described a Esilrr

method of rearing caddis flies. They placed -i.p"e in shallow pie

p-ns containing dnamn srhpmnhain m oss. The moss kept the ..nae roist,

and the pupae received more oxygen than they would have received in

water. TIy method was quantitative rather than qualitative, for if

two or more species of a genus were present, a specific association

could not be n'de. (3) The pupae were separated under a binocular

microscope and npcked, in groups of five, in dG~pn cotton. ach group

was then put in a shell vial covered with a wire screen top. This

senTrpted the species qualitltively, however, only a small percentaPe,

approximately two percent, could be reared since r-!ny pupe were Un-

doubtedly injured in hnndlin. (a balanced

cqFrium- with a strong jet of air eere-ting the water and Incident.lly

stirrin-t the water swiftly and constantly. A slow flow of tap water

fell into the aquarium, and a'slnhonin' arrrncEment took care of the

overflow. The larvae were fed with plnlkton. Time and lack of

eqruiment prevented me from making full use of this method, but I

believe this method was the best and can be used to cdvanate with

both larvae and pupre.

Field Rerinw

On three different occasions I set series of modified, copper-

wire pillow cages filled with larvae and pupae in the west branch of


Iogtown Creek near Gainesville. TheoreticIlly, this should be an

excellent method for associating stges in the life history of cAldis

flies, but in practice it was unproductive. Uore extensive, con-

trolled field reorinr should yield good results.

1n- al Dissection

Certain pupae form the connecting link between larvae and

adults and can be used to associate the adults with their specific

larval forms. In most caddis fly groups the larval scleritts, which

are readily diagnostic to species, are packed into the posterior end

of the pupal chamber after the pupa is formed. Just before emergence

of the adult, the genitalia of both sexes becomes completely formed,

hardened.and colored, which therefore specifically identifies the


If a cocoon or case is collected which has a matire pup? in

it, the larval sclerites and fully formed renitalir can be associated,

and it is thus possible to linkfthe a:1ult and larval forms of the

species. VTowever, it is ,unll:y necessary to collect n.any pupae bs-

fore one is fomud with mature genitalia.

The family Leptoceridae constitutes a major exception to this

type of linkage. In this family the pupal chamber has a slit and not

a mesh in the closing cap at both ends. Through these slits the pupa

pushes out all the larval sclerites, so that it is irmossible to get

associations of adult structures and Inrrvl sclri1tes in the asme

case, For this reason it is neeessary to rear these larvae.

Care was taken in trPnsportlng the larvae and pupae. I hlve

had bent results by packing both larvae and pupme in drmp moss. The

caddis flies were transferred to their permanent aquarium or cage as

soon as possible.

Range Florida, Georgia and Illinois*

Description& Rose,,1948, ,

Renarkt: Ross (1948) states that C. perigua was recorded erron-

eously as sooia and the latter species was thus listed as being

present in Florida. Chimarra sooia does not occur in the state.

According to Ross (1948), "Re-examination of a Irrge series of

Booia---.---( Indxiates) a wide eastern and northeastern range for

scoia and a small range of perig a which is peripheral on the southern

and western portions of the range of soola."

The larvae of C, periua live in clear, cold, rushing water

such as that pouring over the rock dam at Poe Springs. The adults

appear to be negatively phototropic, for though I "lighted" for

caddis flies many times in this locality, I did not collect any


The larva was Pseociatod with the adult by a process of

elimination. I collected larvae of three distinct species of

Chimarra and adults of three species C. aterrima Co perigua and

C. florida. The larva of C. nterrima was previously described and

was easily identified. I associated the larva of C* florida by

pupal dissection, which left one unidentified species, The adults

of C. perigua are very similar to C. sooa, and the third larva

was also extremely similar to that of Co socia. It seems obvious,


therefore, that those larvae must be those of C, porigua,

The larva of C. periiua cannot be distinguished from that

of Ce sooia using the description given by Ross in 1944, I do not

have comparative material of C sooia and, therefore, cannot look

for differences in morpholoSgicn characters between the two species,

but a critical examination of both larvae is definitely in order,

Description: Ross, 1944.

Remarks: This species appears to be rather rare in Alachua County,

for I was able to obtain only a few speoimans.* One larva was found

in a lake, the other in a slow stream with a soft, flooculent bottom.

Vorhies (1909, p. 712) gives an excellent description of the unusual

larval ease.

"The larva burron~ into the sand of the bottom of the

stream and forms a long, often complexly branched case of sand,

scarcely firm enough to keep its shape when it is eXtracted from

its position. This oann, about 5 rmo. in diameter, excepting some

smaller branches, is ofton as muoh as 65 mia in length, the rretter

portion buried, only 10-20 am. projecting from the stream bed."

Although I collected the larvae of this species in a num.

a singlo *speoimen The adults nay be negatively phototropso, for

night lighting and daylight sweeping were both ineffective in col-

looting them. I attempted to rear some larvae which I collected

in Big Hatchet Creek, but the larvae died before pupation.

These larvae appear to be very similar to the larvae of P.

remotus (fig. 68). Since P. remotus has been collected in British

Columbia, Illinole, Minnesota, New Hampshire and New York, a wide-

spread geographic distribution coupled with a looal occurrence ia

indicated. It is possible that the larvae of Polycentropus ap. A

are the undesoribcd larvae of P. ,rassioornia, which has previously

been collected in Florida, but it is also possible that they are

the larvae of P. remotus. Further study will undoubtedly permit

marginalis has been reported from Tennessee, Kentuolj and Alabana

but not from Florida. Although I have not verified the correct-

ness of the identification of the specimens from South Amerioa,

finding this caddie fly in Florida is an indication that it must

ooour in at least limited portions of the intervening territory,

namely Mexico and Central America.

Descriptian: Ross, 1944*

Remarkst Only one North American species, marginalis, is known for

this genus. The immature stages have never been discovered, but

evidence presented here, I believe, will clarify the association of

the various stages. I found two species of larvae which were keyed

(Rose, 1944) to Psychohniid Genus At one of which is to be found

under Psayeholild Genus A in this thesis, and one of which was un-

described. I collected an innature pupa, however, in Lake Vlauberg

which contained the larval solerites of the undescribed species of
Psychomyid Genus A, The fact that these sclerites could be identi-

fied as Psychomyiid Genus A would eliminate Phylocentropus, Neurei*


elip is and Polycentropu. The pupa had a preapical spur on the
front tibia whilh eliminated Cernotinaj, Igpe end Psayohonmia leav-

ing only Cyrnellus and yTtioetphylax The maxillary pelpi, the key

character for distinguishing between the two genera, are identical

with those of Cynellus, so I feel the assooi.tian is a valid one.

It appears, therefore, that tho Lake 1nauberg specimen is the pupa

of C, tmaginalis while the second species still romains iitho:t a

name In PsychoTlld Genue A*

This species is not very abundant in Alaohua County. Ify

records indicate that emergence occurs In the Spring*

Ross (1944) states that the adults are mainly found on

the shoroa of lIrge rivers but also on tse shores of small streams

and lakes. Although I collected adults from rivers and streams,
I found larvae only in lakes.

According t~o illiam Beok, Jr. of the Florida State Board

of Health (personal co~unmioatioin) Cheumatopsychid larvae will

tolerate pollution of a minor degree while most other caddis flies

will not. Personal observation bears this out; for example, in the

summer of 1950 the Eest Brnnoh of Hogtown Creek had a caddie fly

fatma composed almost entirely of Cheumatopsychid larvae, while the

West Branch had a more varied fauna* Many old, empty Leptooelia

and Oeoetis oases s were found in the East Eranoh showing that other

species had lived there. Since it is known that the East Branch

occasionally becomes polluted, it would seem likely that the areek

was slightly polluted in the su.mor of 190Q, and that only the

Cheumatopspyhid larvae could withstand the pollution.

I collected many larvao in Alaohua County, for this genus

is abundantly represented. To structural characters haie yet been

found to separate the larvae to species; therefore, these records

will not be given. Liarrv of Cheumatopsyche are very coacan and

occur in most of the streams in the county*

agree with the description of the species given by Ross (1944), so

I sent them to Dr. Ross for confirmation of identification. He said

they were certainly very close to Cheumatopsyche nphanta, but also


suggested that they might represent a different spooios present in

as questionable until males are secured which would then corroborate

Desoriptiant Denning, 1948,

Romanrks Oxoethira eanxella was described by Dennimg in 1948 on the

basis of two male speimens; one from Winter Park, Florida and the

other from rew Orleane, Louisiana. This species is the only rep-

resentative of the genus Oxyethira that I found in Alaohua County*

Since a lea of janellZ were collected along with females

at both Poe Springs and Vorthingtan Springe, it oan be assumed

that the fonnele are the undoscribed forms of this spooieo. Teny

other females of Ox_0 thirn, collected at the River Styx and Dig

Hatohet Creel., could not be speoificnlly identified due to the fact

that no males were project. In all probability tV'se females be-

long to the apeclea 0. janellea howeverE bor.use of a lack of oomw

parative material, I do not feel that I can place a nnmo oa them

at this time.

Although almost all caddi fliees that are attracted to li)ht

come directly to the source of the light, I noticed that 0* janella

came to the nore dimly illuninatod portions of the hBeet, such as

the back of the sheet, indicating that they are less strongly photo-

tropio than most other species.

BDrner. I was able to collect topotypical material and was aloo able

to collect the uidosoribod larva. This larva, which is fairly

oonrno at the rook dam near Poe Springs makes a purseeshaped onae

of sand grains. The eases are attached to submerged vegetation and

rooks in the slower moving portions of the river around the dam,

The adults are attracted to light, but seem to come to the

light a little later in the evening than most of the other caddis
