Northeastern DSA meeting
in Sussex Co., New Jersey, June 22 - 24, 2007
Being relatively close to home and an area I've visited before, I only
had a handful of species I was targeting for the NE DSA meeting in the
northwest corner of New Jersey. Meetings have advantages and disadvantages
for finding dragonflies. The trip leaders know the area and have species
and locations staked out. Permission to get onto restricted or private
properties have been arranged. With a couple of dozen people covering
any given site, almost every dragonfly gets seen. However not everyone
gets to see every good dragonfly. Another dynamic is some people like
myself will swing the net first, while others would rather lift their
binoculars or angle to get a photograph.
I drove to the Paulins
Kill along the way to the meeting but after a couple of hours did not
see anything exciting. I continued to the Delaware Water Gap and a field
where I had seen one of my targets in the past, Septima's Clubtail, Gomphus
septima. I had collected the species earlier this year in Alabama
but the ones found in the Northeast are septima delawarensis, a
disjunct population. I wanted to see what the differences are. But late
in the day the field was quiet. I was content to collect a couple of female
Rusty Snaketails, Ophiogomphus rupinsulensis, which were common
but there was little else. I ducked into the car while a thunderstorm
rumbled east crossing the river. I waited for the sun to come out again
but it couldn''t entice any Septima's into the field. I never did see
any all weekend.
The meeting officially
began the next morning, catching up with familiar faces and meeting a
few new ones. The group was divided in two, one group to head to the Delaware
for big river odes, the other heading into Stokes State Forest for stream
species. I joined the latter and followed our leader Jim Bangma into the
field. Our first stop was a field owned by the Nature Conservancy. Wind
swept the hillside and the sun played hide and seek behind puffy cumulus
clouds. But there were several species of dragonfly foraging. Snaketails
were high on my list and Nick Donnelly caught a female Brook, Ophiogomphus
aspersus which he graciously let me scan that evening. Thanks Nick!
I was not so lucky
with another snaketail I was hoping for. After stopping for lunch, I got
stuck in traffic and fell behind the caravan. We arrived late at a stream
crossing and was told we just missed a female Riffle Snaketail, Ophiogomphus
carolus. Found by the parking area, it had been netted but then set
on the ground for posed photographs. Despite a net hovering nearby, she
got away. I sure hope someone got some good pictures.
At the same stream,
a female Sable Clubtail, Gomphus rogersi, was caught. There was
talk of posing her too but Jim Bangma knew I needed a specimen for the
book and made sure I received it. Thanks Jim! This is a species I saw
during my last trip to Georgia but weather had prevented me from finding
a female. Later a couple of males were spotted along the stream providing
some good field photo opportunities.
At the picnic that
evening, a trip was proposed to look for Umber Shadowdragon, Neurocordulia
obsoleta on the nearby Paulins Kill. Quite a few of us enthusiastically
agreed to go despite the continuing wind and the evening's drop in temperature.
But by the river the wind died down and it felt warm when a dragonfly
flew by. Another circled out of reach, a female laying eggs. Most of us
sat teetering on a large rock and the water's edge. The water was deep
so wading was not practical here. A couple of people headed down the river
to look for other access points.
Another shadowdragon
skimmed by the rock and Jim Johnson sitting next to me deftly netted her.
A few minutes later, he flicked another one off the surface of the water,
another female. Now I was getting a little antsy. The guys that headed
to find another access point came back to show off a male in the net and
then, just minutes later, two more males, prompting some to abandon our
rock to check out the other site. I doggedly decided to stay now that
there was a little more room. It had gotten pretty dark when a dragonfly
began to circle the black water just below my feet. It's flight was so
erratic I could hardly follow it in the gloom. In desperation I slapped
the net straight down into the water and was rewarded by a slightly wet
but beautiful female Umber Shadowdragon.
I had hoped that I would
be able to scan one of the captured males but they were to be posed the
next day for photographs and then released. It was frustrating since I
needed male scans but since I didn't catch them I couldn't really complain.
The next day I tried
the points along the Delaware River with Allen Barlow leading. Allen had
helped me a great deal with Damselflies of the Northeast so it
was nice to catch up a little with him. We started in a field along the
Delaware, the same spot I had visited on the way out. We found more species,
most warming up in the morning sun. Spine-crowned Clubtails, Gomphus
abbreviatus, were fairly common. There were a few Mustached Clubtails,
Gomphus adelphus, along the edge of the field but the female I
needed flew up and away. I caught a male Rapids Clubtail, Gomphus quadricolor.
Allen and I almost convinced ourselves and everyone else it was a Green-faced
Clubtail, Gomphus viridifrons, a species rare in the area. Later
an real Green-faced Clubtail male was caught and Allen made sure I got
the specimen for the book. Thanks Allen!
Also along the edge of
the field a female Stygian Shadowdragon, Neurocordulia yamaskenensis
was found perched low in a tree. This was another of my target species. The
dragonfly's finder started taking pictures, then more photographers moved
in. I was close enough to see her whirling her wings to warm up her wing muscles
so I knew she wanted to get out of there. But with all the photographers snapping
away I had to refrain from jumping in with the net so I turned my back and
walked away. It didn't surprise me to hear a few seconds later, "There
she goes!" as she flew from sight. As we gathered by the cars to move
on to the next site, I heard a couple of people expressing disappointment
that they had missed seeing the shadowdragon which wouldn't have been a problem
had I netted it. Oh well, later that evening some of us would return to the
Delaware and try to catch a few Stygians during their dusk flight.
But it had gotten even
cooler that night and standing knee-deep in the river I only saw one shadowdragon
flit by. The only one anyone caught that evening took three men to catch.
Fred Sibley tried out a mist net which was held horizontally over the water
by two people. When a dragonfly flew underneath, the plan was to drop the
net down onto the surface of the water. The third person had to fish the dragonfly
out from under the net. I think the method has a lot a promise. But it took
a extraordinary effort to catch one female Stygian that night when a flick
of the net would have resulted in the same catch earlier that day. But I guess
it wouldn't have been half as fun.
I did get to scan
that female that Fred and company caught. Thanks Fred! Oh and remember
those three male Umber Shadowdragons that were slated for release? Well,
one died in custody, so I got to scan that one too. |
