Texas, June 7-20,
2008
A lot happened during this two week trip to Texas. I saw a lot of exciting
dragonflies and hit most of my targets. While seeking a dragonfly newly
added to the U.S. list, we found another U.S. record. But it was one of
the most grueling trips I've taken so far, long hot days with triple digit
temperatures and high humidity, sleep deprived nights scanning, and long
driving distances between locations. And there were the calls home. Worried
how the boys would adjust to the new sitter (not too well). Then it rained
at home and the lights went out and my basement and studio flooded (again)
only I wasn't home to help clean it up.
Saturday, June 7:
Air travel these days is a nightmare. Mine began the day before when I
got an automated phone message informing me that my flight was already
cancelled. I was rebooked on a later flight so I would get into Austin
at 1:30 PM instead of 12:30 PM. Still that should be enough time to get
in the field for a couple of hours. The nightmare continued with a call
waking me up at 5 AM from American Airlines saying my rebooked flight
was also cancelled and now I was on a flight to Chicago. Not only was
the connecting flight to Austin scheduled to arrive later (3:30, now little
time in the field) but the first flight was to take off earlier in the
morning so I had to get up and get moving. I held on the line and got
a real person to yell at although it didn't make me feel any better or
get me a reasonable explanation.
I had to call to wake up Fabrice de Lacour who was accompanying me on
the trip so he could get going earlier. We got to LaGuardia and waited.
Suffice it to say we did not get to Austin at 3:30 and we did not make
it into the field. However Giff Beaton visiting from Georgia and Greg
Lasley of Austin did and they had caught me a couple of local species
I wanted to see, Four-striped Leaftail Phyllogomphoides stigmatus
and Broad-striped Forceptail Aphylla angustifolia. We met
up them and John and Kendra Abbott at Greg's house for pizza and beer,
a fine way to unwind after our air travel ordeal.
Sunday, June 8:
Greg and Giff picked us up at our motel the next morning and we headed
off to look for Stillwater Clubtail Arigomphus lentulus
at the only site that Greg knew for it. He had seen them less than a week
before so they should still be flying. It was a little farm pond or "tank"
as the locals call them. Only one edge of the tank was accessible by the
road while the rest of the pond was behind a barbed wire fence. We combed
the road edge, flushing up a couple of deer fawns, found a Sulphur-tipped
Clubtail Gomphus militaris and some Setwings Dythemis
species but no Stillwater Clubtails. As we were just about to give up
Fabrice and I spotted a couple of clubtails flying at the pond edge but
on the other side of the fence. It took some doing and coordination but
we did manage to net a couple of males.
We headed back towards Austin making a couple of stops for Jade-striped
Sylph Macrothemis inequiunguis. Again Greg had scouted them
during the previous week and found some that were flying. An odd, tiny
species, males patrolled forest clearings where they would disappear from
view into the shade. We saw a couple flying high among the treetops. One
surprised us by flying low but he escaped without a swing. Fabrice having
gone down into the stream, caught a female laying eggs underneath the
tunnel of the road crossing but we left without catching a male.
We made a couple more stops at parks in and around Austin in the afternoon
before calling it a day. We saw a good number of species including many
Four-striped Leaftails and some of the Texas variety of Cobra Clubtail
Gomphus vastus. The Cobras here have reduced pale spots on
a very brown club.
Monday, June 9:
We returned to Southeast Metro Park in the morning to look for Jade
Clubtail Arigomphus submedianus at a small pond there. It was
frustratingly windy (especially for the photographers) and we had little
luck at first. Giff spotted a Jade that flew off. I waited around the
pond catching a couple of male Broad-striped Forceptails which I needed
then finally caught a male Jade Clubtail after stalking him as he flew
from bush to bush.
Giff had to head back home and work so after dropping him off at the airport,
Greg drove us all the way to San Antonio to look for Gray-waisted Skimmer
Cannaphila insularis which Martin Reid had seen at a park on
the San Antonio River the day before. We found several males on a little
shady stream. We thought we had a female by the river itself (more the
size of a small creek) but it turned out to be an immature male. We saw
a few other interesting species including Slough Amberwing Perithemis
domitia, a variety of Dancer (Argia) species, and a intriguing
Forceptail that flew away unidentified.
Tuesday, June 10:
Tuesday was a travel day but Fabrice and I made one stop for a male Jade-striped
Sylph in the morning. We arrived early at Walnut Creek Park where we had
seen them flying on Sunday. We were hoping to find a male feeding lower
to the ground but intially we didn't see anything but Setwings. Later
I saw a single male Sylph flying high above a clearing then nothing for
quite a while. The morning was frustratingly cloudy. Along the trail I
caught a female Pale-faced Clubskimmer Brechmorhoga mendax
then let her go. I went back to the stream and passed some time taking
pictures of Dancers, Kiowa immunda, and Springwater plana.
I was photographing a Neon Skimmer Libellula croceipennis
when a female Jade-striped Sylph landed in a nearby tree, her dark wing
tips conspicuous. After she flew off I went looking for Fabrice to see
what he had found. He had been watching two male Sylphs flying high above
a wooded trail. We kept an eye on them for a long while but they did not
come lower and eventually they disappeared as the sun and temperature
rose. Later as I was making my way through a narrow trail I saw a little
movement in the shade as a small dragonfly flew and hung up in the twigs.
It was a male Sylph and I cursed the close branches that I feared would
get in the way of the net.
Having caught the Sylph we headed south towards the lower Rio Grande Valley
a little over 300 miles away. Exciting things had been seen recently and
we were anxious to get there.
Wednesday, June 11:
The most exciting dragonfly we were hoping to see was Scarlet-tailed
Skimmer Planiplax sanguiniventris a species new to the U.S.
that had been discovered on June 2 at Bentsen - Lower Rio Grande Valley
State Park. It was initially thought to be the similarly patterned Flame-tailed
Pondhawk Erythemis peruviana but photographs taken by Martin
Reid and David and Jan Dauphin proved otherwise.
Fabrice and I were wading the resaca lake at Bentsen Wednesday morning.
We were told the Planiplax did not appear at the water until 10:30
AM but we tried earlier anyway. Fabrice caught a dragonfly that we thought
at first was out target. Like the Planiplax it had a red abdomen
and a dark wing patch at the base of the hind wing but nothing else was
right. Later we caught a real Planiplax and the differences were
stark. But we couldn't put a name on it. It also behaved quite differently,
the Planiplax occasionally perched but our mystery dragonfly was
a flier. I thought it might be Garnet Glider Tauriphila australis,
a species recorded a few times in Florida which I have not seen alive
so I was unsure. We put it aside to examine later.
The afternoon grew hot. We looked for Carmine Skimmer Orthemis
discolor but found none at the spots I saw them in April. Later we
went looking for Black Pondhawk Erythemis attala, Turquoise-tipped
Darner Rhionaeshna psilus, and Ringed Forceptail Phyllocycla
breviphylla. We saw a male pondhawk but it got away, but found both
sexes of Three-striped Dasher Micrathyria didyma. As I watched
Fabrice try to net a Ringed Forceptail, I felt something biting at my
ankles. Fire ants were attacking my legs. I jumped around trying to swat
them all off but I got bit badly. Despite a generous application of DEET
we were also plagued by mosquitoes. And chiggers. And ticks. I'm still
itchy.
Going through the literature and my library of photographs that evening
we quickly identified our mystery dragonfly. It was in the same genus
as Garnet Glider (a good guess though) but a new species to the U.S. That
night I sent out an e-mail to various experts:

Subject: Bentsen Planiplax collected plus another interesting species
Hi All,
Yesterday (Wednesday, June 11) Fabrice de Lacour and I managed to collect
(under permit) a male Planiplax near the boatlaunch at Bentsen State Park
in south Texas. We saw at least 5 individual males along a 250 yard stretch
of the lake. They were difficult to catch as we had to wade in the waist
to chest deep water along the shoreline vegetation.
During our Planiplax hunt, Fabrice also netted a reddish dragonfly male
whose identity initially eluded us. We saw at least 3 other individuals.
I have posted photographs taken in the hand, a dorsal scan and scans of
the appendages. We believe that it is yet another new species for the
U. S. but would like confirmation.
The next night we posted our find to the TexOdes and Odonata-1 lists:
Subject: Another U. S. record at Bentsen

Fabrice de Lacour and I are currently in the middle of a two week trip
to observe, photograph, and collect dragonflies in Texas. We spent the
first couple of days in the Austin area then headed to the Lower Rio Grande
Valley on Tuesday. We had been following with great interest the recent
string of "firsts" for the Valley particularly the first U.
S. record of Planiplax sanguiniventris at Bentsen-Rio Grande Valley State
Park. Under permit from Texas State Parks we sought to collect a specimen
of the Planiplax for the Odonate Survey of Texas at the University of
Texas.
So on Wednesday morning, June 11, we were wading in La Parida Banco resaca
in Bentsen State Park just west of the boatlaunch where Planiplax has
been seen. This species has a dark gray thorax, a bright red abdomen,
and dark patches at the base of the hindwing. On the resaca there were
a number of dragonfly species flying that are somewhat similar in color
and pattern including two Tramea species, Libellula needhami, Dythemis
fugax, Orthemis ferruginea, and lots of Brachymesia furcata.
Fabrice netted a dragonfly with a red abdomen, dark patches on the hindwing,
but the thorax was a deep red. We puzzled over its identity. It certainly
was not the Planiplax which we later did manage to collect. I suggested
it might be Tauriphila australis Garnet Glider but consulting our trusty
Needham, Westfall, and May, it's strongly curved cerci identified it as
Tauriphila argo, a neotropical species not previously known to the U.S.
The common name listed in NWM is Bow-tailed Glider.
We returned to the site the next morning, June 12, and observed at least
2 dozen male Tauriphila. We saw tandem pairs that could have been this
species but were unable to catch any. Males fly short beats along the
water's edge often chasing and being chased by other dragonfly species.
They were best observed while wading but probably can be spotted through
the considerable screen of cane along the shoreline.
Additionally we observed 5 male Planiplax on June 12.
Friday, June 13:
We headed to Santa Ana NWR in the morning but found it disappointingly
dry and we worked around what little water was there. I had obtained a
permit to survey there and felt bad that I really couldn't do any work
for them. Our best sighting was a Bobcat and a youngster that wouldn't
flush from a cool shady spot. In the late afternoon we concentrated on
finding Turquoise-tipped Darner managing to catch a couple of females
along an irrigation ditch near Bentsen.
Saturday, June 14:
We were back at Bentsen at the resaca in the morning looking for female
Planiplax and Tauriphila. Fabrice kept cool wading the circumference
of the lake while I walked some nearby trails and fields. I saw a couple
of Bow-tailed Gliders circling over a field and netted one but it was
a male. Fabrice found them common all around the lake so there is quite
a population in the park. Also at the resaca were good numbers of Narrow-striped
Forceptails Aphylla protracta, Tawny Pennant Brachymesia
herbida, and Spot-tailed Dasher Micrathyria aequalis.
I caught a female Spot-tailed ovipositing alone on the lake but found
several more in the shade of the trees along the shoreline.
Having caught females the day before we tried for male Turquoise-tipped
Darners. Fabrice caught a surprise Black Pondhawk but the darners continued
to elude us. We would see them flying and hanging up but approaching them
through the brush and down slippery muddy ditches was difficult. Finally
I caught a young male that just happened to land next to me. I went to
find Fabrice and found he had just caught a mature male. Thoroughly mosquito-bitten
we were happy we didn't have to try again at this site.
We also caught the weird dragonfly. It hung up in the shade just like
the darners. It was darner-sized, the body was pale tan and it had just
the barest wing markings, a small dark triangle at the wing base and amber
wing tips. Green eyes. We didn't recognize it and we thought we had something
really good. Another U.S. record? The wing venation placed it in the Emerald
family but what was it? While Fabrice was photographing it in the motel
room it briefly got free. As it flew around the room it's shape and wing
pattern suddenly seemed very familiar. I compared it to the scans of Prince
Baskettail Epitheca princeps that I had on my laptop.
It's structure matched but it's coloration made it the strangest individual
I've ever seen.
Sunday, June 15:
We were pretty wiped out at this point. The heat, humidity, and the lack
of sleep was getting to us. We thought we would sleep later but Martin
Reid called us from the Bentsen visitor center where he was looking at
a female Claret Pondhawk Erythemis mithroides. We got there
as quick as we could but the pondhawk was gone. I had a Bow-tailed Glider
flying right outside the visitor center. I was hoping it was a female
but I somehow missed catching it. (Later in the week Martin would find
more female Gliders foraging nearby and catch a female Claret Pondhawk).
We weren't so fortunate but perhaps with the large numbers of Gliders
present this population will persist until we make another visit.
Monday, June 16:
We made a half-hearted search for the Claret Pondhawk at the Bentsen visitor
center then visited the McAllen Nature Center hoping for a female Gray-waisted
Skimmer. We found the Golden-winged Dancers Argia rhoadsi reported
there and we did see some Gray-waisteds along the stream but could not
catch any. We then drove the 400 miles to the town of Cleveland, north
of Houston and near Sam Houston National Forest.
Tuesday, June 17:
I dropped Fabrice off at the Big Creek Scenic Area in the National Forest
then headed back to the motel where I had left my camera. When I got back
he had caught a female Gulf Coast Clubtail Gomphus modestus.
It the morning gloom it was flying over the creek and would be the only
one we would find. Our main target for the area was Texas Emerald
Somatochlora margarita. We didn't see any flying along the dirt
roads so we tried a couple of wide trails through the woods. Along one
of the trails we saw the narrow-waisted profile of an emerald flying high.
We tried a number of locations throughout the long sultry day but saw
very little.
Wednesday, June 18:
We concentrated on the one trail where we had seen a couple of emeralds.
We had some tantalizing flybys in the late morning. They were erratic
but low. Emeralds for sure but what species? Mocha Emerald Somatochlora
linearis was also present but it is a larger and longer bug. The few
flying high seemed small and were almost certainly margarita. We
passed the time trying to catch Georgia River Cruisers Macromia
illinoiensis georgina and comparing the females and immature males
of various species of Skimmer Libellula that were along the trails.
In the late afternoon I finally caught an emerald but it was a Mocha.
Thursday, June 19:
We tried one last time for Texas Emerald in the morning. We saw a couple
flying high at a clearing early - then nothing. For a couple of hours
we scrutinized small gatherings of Wandering and Spot-winged
Gliders Pantala flavescens and hymenea but none had
the right spindle-shaped abdomen of an emerald. Occasionally a Black
Saddlebags Tramea lacerata would join them, a River Cruiser
Macromia would cruise by or a Swamp Darner Epiaeschna
heros would fly in and terrorize the Gliders. We made one last slow
drive down the dirt forest roads and we spotted one male Texas Emerald
coursing a small pattern in the sky. We watched it for 20 minutes before
it flew off, never coming low enough for a swing.
Reluctantly we had to give up, our one true miss of the trip, and began
driving towards Austin. We headed to San Antonio for another chance of
finding a female Gray-waisted Skimmer. While we were down in the Valley,
Greg had revisited the site and seen females early in the morning then
observed as they were eventually displaced by males. We thought we try
on our last morning, Friday, but since we arrived in San Antonio at 5:30
PM we took a look at the park. Almost immediately we found several females
by the river so we were done.
I got on the phone and arranged to meet Martin Reid in the park. We were
picking up his recent specimens to give to John Abbott in Austin. He had
collected a female Bow-tailed Glider and Claret Pondhawk and I wanted
to see, photograph, and scan them. How I would have liked to see them
alive! We talked with Martin for a while, said our "Goodbyes"
and headed back to Austin.
Friday, June 20:
Greg stopped by our motel the next morning to pick up Martin's specimens
for John. We also gave him our specimens of the first Planiplax sanguiniventris
and Tauriphila argo collected in the U.S. Not bad. Greg headed
that day to Gonzales, TX where he found a couple of female Blue-faced
Ringtails Erpetogomphus eutainia a beautifully patterned species
I hope to see when I head back to Texas later this summer.
We didn't go into the field that morning but hung out at a bookstore before
heading to the airport. Air travel is a nightmare these days.
I are truly grateful for the generosity, assistance, guidance, and
companionship provided by Fabrice de Lacour, John Abbott, Greg Lasley,
Giff Beaton, Martin Reid, David and Jan Dauphin, Josh Rose and the staff
at Bentsen LRGV State Park and Santa Ana NWR. Thanks to David Riskind
for granting permission to collect at Texas State Parks and Mitch Sternberg
for permission to collect at Santa Ana/LRGV NWR.
