THE FLORIDA ENTOMOLOGIST
SOME DRAGONFLIES OF EARLY SPRING
IN SOUTH FLORIDA
By JAMES G. NEEDHAM
This is brief summary of the results of two months' collect-
ing for Odonata in and about the Archbold Biological Station
in Highlands County, Florida. During March and April of
1945 I was privileged to make that Station my field headquar-
ters. I was given much aid toward getting to the lakes and
streams of the interesting region round about. Mr. Richard
Archbold took me to the more distant collecting places and
helped me in many ways besides. Mr. Simeon Walter gave me
many a ride to lakes that lay along his daily route of travel
for the Station. Mr. Leonard J. Brass, botanist for the Station,
often went out with me, and was an excellent co-laborer, assist-
ant and guide. Mr. Dennis Hinchey went collecting with me a
number of times, and brought me many fine specimens of adult
dragon flies. The atmosphere of the Station was altogether
congenial and helpful.
The best season for collecting well grown nymphs was at
hand when I arrived on March first. A protected pool of run-
ning water near the laboratory provided a safe place to set
my rearing cages. I was able to bring a considerable number
of nymphs to their adult stages, and to add something to our
knowledge of dragonfly life histories. This paper is a brief
statement of what I found in the region about the Station.1
A few notes on the breeding grounds of the dragonflies found
may be of use to future collectors in that region. I did most of
my collecting in the clear sand-bottomed lakes that nestle among
low hills in Florida-scrub vegetation. I sampled a few spots on
the shores of a dozen lakes. I was able to make several trips
to Lake Placid, but only one stop of an hour or two at each
of the others. None was within easy walking, distance of the
Station, and war-time restrictions on the use of tires and gaso-
line hindered getting about. I collected in four streams and
in several drainage ditches. I will first briefly mention some
characters of my collecting places, and then I will add a locality
list of the 55 species of dragonflies collected.
The lakes that I visited varied greatly in size. Lake Istok-
poga, the largest, is some ten miles long and nearly as wide.

VOL. XXVIII-No. 3
In descending order Lakes Placid, Stearns and Jackson are each
about three miles across. Next come Lakes Huntley and Grassy,
each about two miles long and half as wide. The other six are
smaller, but not too small for heavy wave action on their shores
in times of storm. In outline the smaller lakes tend to be saucer
shaped in circumference and in depth. All of the lakes are
shallow; one may wade out far from shore in all of them, and
at almost all points in the shore of most of them. Where the
banks are lowest the dense vegetation of bordering swamps
edges out into the water. All these lakes, and the streams as
well, are shown on the current county map of Highlands County,
The lake shores are fringed almost everywhere with rooted
aquatic vegetation. The principal component of the outer vege-
tation zone in the deeper water is a grass of the genus Panicum
(P. nemitomon). It spreads by long runners, buried in the sand
and rooting at the nodes. It sends up thin and pliant, waist-
high, leafy stems. These stems stand in open order. They
sway in the wind and rise again unharmed when beaten down
by the waves; there is no entanglement of them to impede one's
wading about. They thinly occupy broad belts of the shore in a
nearly pure stand.
This panic grass is sometimes replaced by, but more often
intermixed at its border with, the stubby sedge, Fuirena scir-
poidea. The sedge tends to keep more closely to the shore. Its
strongly rooted runners lie on top of the sand. They run criss-
cross, and become interlaced in a wide-meshed pattern of poly-
gons. The stems are often badly broken and reduced to stubs
by wave action.
These two plants, panic grass and sedge, together provide
the main shelter for bottom-dwelling dragonfly nymphs in the
lakes. By their strong roots they hold the sand and make a
terra firm of it, where nymphs of several genera may dwell.
The nymphs of Celithemis sequester themselves at the bases of
the erect stems. They stick so closely to shelter that few of
them are taken in a rake-net sweeping the bottom, but after
transformation their cast off skins are left hanging in the grass
stems in great abundance. Nymphs of two species of damsel
flies, Enallagma sulcatum and E. durum seek the same shelter,
and are even more difficult to dislodge with a rake net.
The nymphs of Gomphus cavillaris burrow in the sand in
the intervals unoccupied by the roots of the plants. When the
THE FLORIDA ENTOMOLOGIST
vegetation zone is wide they climb the stems of the plants to
transform, but when it is narrow and more open they seem to
prefer to crawl out on shore and leave their cast-off skins lying
flat on the sand just beyond the farthest reach of the waves.
The nymphs of Progomphus alachuensis, superb burrowers,
seek more open spaces where there is some shifting of the sand
in storms. Their tracks may be found in the wider intervals
between the grass roots; more abundantly in sand bars, and
in the bare beds of shore pools. Their tracks are like those of
moles in miniature. The sand is scraped aside by the fore and
middle legs, and the roof of the burrow is lifted by the wedge-
shaped head. There is this difference: the upturned end of
the abdomen, that lifts the caudal respiratory opening up to
clear water for respiration, as drawn forward, cleaves the roof
of the burrow and leaves a little groove down the middle of it.
The nymphs of Progomphus move shoreward as they near
the time of transformation. They generally leave their skins
lying flat on the sand of the shore. Only rarely will one climb
a pier or other vertical support, and then that support must be
far out from shore and must have a rough surface into which
the nymph may hook its claws.
The huge nymphs of Didymops floridensis, that can live only
lying flat upon the sand of the lake bed, must have room for
the spread of their long legs. They probably live in the deeper
water, out where I did no collecting, beyond the panic-grass
zone. I caught no nymphs, save for one taken in transformation,
but found many cast-off skins in the edges of all the smaller
lakes. Any post or pier that projected well above the water
attracted these wide-bodied sprawlers, and was likely to be
besprinkled with their emply skins. Lacking such broad sup-
ports, the nymphs make shift to clamber up grass or sedge
stems when several of these stand close enough together to
accommodate the wide reach of their legs. Very few of them
go as far as the shore for transformation.
On sheltered spots in the lake shores, where pickerel weed
(Pontederia) and bonnets (Nelumbo) flourish, conditions are
entirely different and more like those in small weedy ponds and
ditches. My collecting was mostly done on sandy shores where
wading was possible.
The streams in which I collected nymphs were all sandy-
bottomed and muck-bordered and bedded. Wading was best
at the edge of the water where (in this season of extreme
VOL. XXVII-No. 3
drouth) there was generally a footing of compacted bare sand.
On either side was muck: soft black muck. Over the few sand
bars the water was coffee colored; over the muck it was black
The largest of the streams visited, Fish-eating Creek, some
sixteen to twenty miles from its mouth, was reduced by the
drouth to a series of long muck-bottomed pools. .Arbuckle Creek
was similar but smaller, with continuing slow current. The best
collecting for nymphs was found in two smaller streams:
Josephine Creek at State Highway No. 8 and Yellow Bluff Creek
at the crossing of the road that runs eastward from DeSoto City.
The drainage ditches presented conditions approaching those
of weed-choked small ponds, and sheltered much the same sort
of dragonfly fauna. They varied in size from that of a big canal
near Moorehaven to the little concrete-lined ditch that runs
through the Station grounds. Muck bottoms and steep sandy
sides characterized all the larger ditches.
Two ponds are worthy of mention: two of very different
character. One of them afforded good collecting. It was situ-
ated in the pine flat woods a mile and a half walking-distance
from the Station. It was broad and very shallow. Reduced at
least nine tenths in area by the drouth, it still covered an area
of several acres. Lacking a name, and because its waters were
densely filled over a large part with the coarse loose-jointed
bog moss, Sphagnum macrophyllum,2 I refer to it in the follow-
ing list as Big Sphagnum Pond.
The other pond was smaller and deeper. It is situated in
an orange grove in the northwest quarter of the city of Lake
Placid. The shores of this pond were difficult of approach, be-
cause of a zone of head-high bracken fern and a tangle of tough
vines; and it was hard to collect from, because of a floating
border that would not sustain's one's weight. Libellula auri-
pennis was common there, but hard to catch.
There was another altogether unique collecting place for
dragonflies directly in the Station building. The machine shop
is an excellent trap for wide ranging species. It has a wide
door that stands open most of the time, and high above the
door near the roof is a large window. Dragonflies speed in
at the door, and seeing the flood of light from above, they try
to fly out at the window; and there they become entangled in

the webs of spiders spun in the angles of the window panes.
Their blood is sucked, but their wings and other hard parts,
by which they may readily be recognized, remain and accumulate
in copious layers of dust-besprinkled spider silk. With Mr.
Dennis Hinchey's aid and by use of a long bamboo pole, I ob-
tained specimens of fifteen species from that window-more
species than I got from any other single collecting place visited.
These species are marked with an asterisk (*) in the following
list. The list includes 55 species.

Two species of the preceding list were collected only from
the shop window: the big Southern Somatochlora filosa and the
slender Neotropical Miathyria marcella that I once before re-
corded from Florida (Entom. News 44: 98, 1933), and that had
earlier been taken by Professor C. T. Reed at Kingsville, Texas.
There were two species found in the window in far greater num-
bers than all the others: the elusive Gynacantha nervosa that
flies at nightfall, and the ubiquitous and familiar Pachydiplax
longipennis that flies by day.
I left off collecting at the Station on April 23, before the
late-season species had put in an appearance. Celithemis fas-
ciata was just beginning emergence (eponina, ornata, bertha and
fasciata being the chronological order of appearance in that
genus), and Didymops floridensis was practically at the end of
its season of flight. At that date I had seen only a single
specimen of Lestes, no Plathemis at all, and only nymphs of

U. C. LOFTIN DIES
On January 16, our Society lost another of its beloved mem-
bers in the death of U. C. Loftin, which occurred in Washington,
D. C. He died of a heart attack at the age of 55. All of our
members who attended the University during the years 1910-
1913 will remember Mr. Loftin. He was a graduate student in
the University and an assistant in the Department of Ento-
mology of the Experiment Station during those years, receiving
his master's degree in 1913. His thesis was on the distribution
of mosquitoes, particularly as to the time of year when different
species were most abundant. For this purpose, he ran an ex-
tensive line of traps. A copy of his thesis is in the University
Library. Mr. Loftin was dearly beloved by all those with whom
he was associated.
The 8 years following the receipt of his master's degree
were spent in research on insects of cotton and sugar cane for
the Bureau of Entomology of the U. S. Department of Agri-
culture, working in Louisiana and Texas. In 1921, he was em-
ployed as manager of the Tlahualilo Agricultural Company of
Mexico, a position which he held until 1928. He then served
one year as Entomologist of the Cuba Sugar Experiment Sta-
tion at Baruga. Early in 1931 he returned to the Bureau of
Entomology of the Department of Agriculture as investigator
in Puerto Rico and the Virgin Islands. In that year he was
VOL. XXVIII-No. 3
called to Washington as Assistant Head of the Division of Cot-
ton Insect Investigation under Dr. R. W. Harned.
Mr. Loftin was born at Mt. Olive, North Carolina, July 2,
1890. He graduated from the North Carolina State College
in 1910. Mr. Loftin was one of the first to recognize the im-
portance and seriousness of the white fringed beetle outbreak
in Florida and Alabama. Besides the Florida and Texas Ento-
mological Societies, he was 'a member of the American Asso-
ciation for the Advancement of Science, the American Asso-
ciation of Economic Entomologists and the Entomological Society
He is survived by his wife, Mrs. May LeBeuf Loftin, his son,
Lt. U. C. Loftin, Jr., of the U. S. Army Air Corps, his daughter,
Aimee Loftin and his mother, Mrs. J. O. Loftin, together with
5 sisters and 3 brothers. His loss will be keenly felt and re-
gretted by all who knew him.
A recent bulletin from the Estacion Experimental Agrono-
mica, at Santiago de las Vegas, Cuba will be of much interest
to entomologists, especially to those of us in Florida, "Catalogo
de los Insectos que Atacan a las Plantas Economicas de Cuba"
by Dr. S. C. Bruner, L. C. Scaramuzza and A. R. Otero. The
insects are recorded under the names of the hosts. This, with a
supplement, occupies 189 pages and should be very interesting
to anyone interested in the insects of economic plants in Cuba.
There are 12 plates illustrating Cuban insects. And then fol-
lows an index in which the insects are recorded in order, which
occupies 11 pages. Three pages are given over to the index of
the predators and parasites of these insects attacking cultivated
crops. Nine pages are occupied by our index of the common
names of the plants.

SOME AUGUST SKIPPERS OF THE GREAT SMOKY
MOUNTAIN NATIONAL PARK AND VICINITY
J. R. WATSON
During August of 1942 and again of 1944 and 1945, it was
the writer's privilege to study the skippers of the Great Smoky
Mountain National Park and vicinity, especially in Gatlinburg,
Tennessee. All skippers recorded, if not in the park, were
collected within a mile or two of the park and undoubtedly occur
in the park. The inability to bring up an automobile in 1944,
restricted much of the author's collecting to the city of Gatlin-
burg, although Mr. Arthur Stupka, park naturalist was most
cooperative in furthering the work. Any success we may have
had was due largely to his help and encouragement. There were
in the collection of the park naturalist, fourteen species of skip-
pers. Those of this list, not in the collection, are starred.
Duplicates, however, of most of them will be placed in the col-
(1) Epargyreus clarus (Cramer) E. tityrus Fab., Silver-
spangled Skipper. This is one of the most common skippers
in the park, during August; the most common in 1944 but in
1945 yielded first place to Polites (Atalopedes) campestris. It
is particularly common in the lower part of the park around
Gatlinburg, but was taken at higher elevations including Indian
(2) Urbanus proteus (Linn.), Long-tailed Skipper, adult
of the bean leaf-roller. Two of these were seen in 1944 on the
hotel grounds at Gatlinburg, at flowers within a half mile of
the park. The writer had no net at the time and they were
not captured but this skipper cannot be confused with any other,
so there can be no doubt of its presence in the park although
it is by no means common. It is relatively rare as compared
with points further south, especially Florida, where, in August,
it would be our most common skipper. A southern species, it
has been reported from New York and Alberta, Canada.
(3) Thorybes bathylus (Smith and Abbot), the Southern
Dusky-wing. Taken at Lespedezia near headquarters in the park,
on August 24, 1944, and August 9, 1945.
VOL. XXVIII-No. 3
(4) T. confusus Bell, Bell's Dusky-wing. Taken at Lespe-
dezia at headquarters August 19, 1944, and in Gatlinburg on
August 17 and 24, 1944.
(5) Achalarus lycides (Smith and Abbot), the Hoary Edge.
Taken near headquarters on the 19th and also at the hotel
grounds in August 1944; at Elkmount on August 19, 1942.
There were more in 1945. This does not seem to be a common
skipper anywhere, at least not in Florida.
*(6) Hesperia communis (Grote) (H. tessellata Scud.),
Common Checker-spot. Taken throughout the extent of the
park; from Gatlinburg to Clingman's Dome (8/21/42; not
nearly as common as it would be in Florida in August. H.
syrichtus (Fab.), the Blue-gray Skipper, which would be equally
common in Florida, was not seen in the park.
*(7) Pholisora catullus (Fab.) The Sooty-wing. Taken at
Gatlinburg on flowers, 8/14/44 and 8/24/44.
*(8) Thanaos martialis (Scud.) August 11, 1945.
(9) Erynnis juvenalis (Fab.) (Thanaos juvenalis) Juvenal's
Dusky-wing. Taken at the Ashhopper Branch on August 15,
(10) Erynnis horatius (Scudder and Burgess), 8/12/45 at
5,000 ft. level.
(11) Ancyloxypha numitor Fab. The least Skipper. This,
the smallest of the skippers, was taken at Gatlinburg on August
18, 29, and 30, 1944, at a swampy spot where the LeConte Creek
joins the Little Pigeon River. A very common skipper in
Florida but confined to low ground along streams. It would
be expected to occur in Cade's Cove and other suitable localities
(moist to swampy) but a diligent search on August 13, 1945
failed to reveal its presence there.
*(12) Hylephila phylaeus (Drury). The Fiery Skipper.
Taken on the Greenbrier Road, 8/12/42; at the hotel grounds,
8/21/44-three specimens in Gatlinburg, within a stone's throw
of the park boundary, 8/27/44; and along Bascome Creek,
8/30/44. This is a southern type, very abundant in Florida.
It extends as far south as Patagonia. Its larvae feed on grasses.
Cade's Cove, 8/13/45-2 males.
THE FLORIDA ENTOMOLOGIST
Polites brettus (Baisd and Lee). The Whirl-about. A south-
ern type, whose males are very similar, very common in Florida,
was not taken.
(13) Polites verna (Edw.) The Little Glass-wing. Taken
on Lespedezia in the park near headquarters, 8/8/42; 8/9/45;
8/16/44; 8/30/44 and 8/21/44; on Greenbrier Road, 8/12/42,
at clover bloom; 8/16/42, Elkmount Road, inside the park; and
Clingman's Dome, 8/21/42; on ironweed, 8/21/44 at Ashhopper
Branch. It was very much more common, apparently in 1942
than it was in 1944 or 1945. A northern type, which, however,
is occasionally taken in Florida.
(14) P. manataaqua (Sa-nd.) The Cross-line Skipper. At
Cade's Cove, 8/28/44. This is a northern type that extends
*(15) P. peckius (Kirby). Peck's Skipper. Clingman's
Dome, 8/21/42. A widely distributed species extending from
Canada to Central America.
*(16) P. (Atalopedes) campestris (Boisd.) The Sachem was
the most common Skipper in the region in 1945. It was espe-
cially numerous at blossoms of ironweed. It was also taken at
a mud puddle on August 26, 1942 and at Eupatorium blossoms
at an elevation of 4,000 feet on August 26, 1942. It is more
common in the lower altitudes than higher up. In 1945, males
predominated up to August 15, females after that date.
*(17) Catia otho egerement (Scud.) is called the Otho
Skipper, taken near headquarters, 8/12/44.
*(18) Atrytone ruricola (Boisd.), the Dun Skipper, at Ash-
hopper Branch, 8/25/42, 8/11/45 and 8/9/44.
(19) Poanes zabulon, the Zabulon skipper, 4 males taken
at Clingman's Dome, 8/21/42; 2 females, 8/25/42; near head-
quarters; at ironweed, 8/25/44; Bascome Creek, 8/30/44; Roar-
ing Fork, 8/19/45, male; on a piece of mouldy bread, 8/15/45,
(20) Megistias 1-herminieri (Latrelle), the Fuscus Skipper,
taken at Ashhopper Branch, 8/12/42; Cade's Cove, 8/13/45.
(21) Polites taumus (Fab.) Cade's Cove, 8/13/45 male,
4 females, ditto; Cade's Cove, 8/28/44.
VOL. XXVIII-No. 3
*(22) Limochoris palatka Edwards,? A single specimen
of apparently this species was taken in the Park in 1945. The
specimen was smaller and paler than those taken in Florida
but seems definitely to belong to this species though far out of
its known range.
The following are in the park collection but were not taken
by the author either year:
Lerema accius (Smith and Abbot). Common in Florida
Panoguina ocola (Edwards). Abundant in Florida
Amblyscirtes vialis (Edwards)
Poanes hobomok (Harris)
Thorybes pylades (Scudder)
DISTRIBUTIONAL NOTES ON TWO SPECIES OF
An Addition to the Thysanoptera of the U. S.
Some months ago, the writer received from William Procter
of the. Mt. Desert National Park, Maine, a collection of Thysa-
noptera for identification. Among them was a specimen of a
species of Taeniothrip collected by him from "Double Phlox"
in June of 1945. The writer sent the slide to Dr. Dudley Moul-
ton for identification. Dr. Moulton identified it as T. atratus
Hal. This, though a common species in Europe, has not hereto-
fore been collected in North America. The slide, returned by
Dr. Moulton, is now in the writer's collection. He has speci-
mens of this species collected by the Bureau of Entomology
and Plant Quarantine from the following plants from Europe:
Asters, Cabbage, Carnations, Castor beans, Clover, Echium
vulgare, Heather, and Poppy, showing a wide diversity of host
Frankliniella bratleyi Wats. in Georgia
The writer has received from Theo. L. Bissell of Experiment,
Georgia, some specimens of Frankliniella bratleyi Wats., which
were taken from tuberoses at Thomaston, Georgia. This con-
siderably extends the known range of this species, which was
heretofore known only from Gainesville, Florida. It was de-
scribed from tuberoses (Fla. Ent. XXV, No. 2; June 1942).
The writer would be interested in seeing Thysanoptera collected
from tuberoses from other localities. W
