Subject: [NatureNS] uncommon waterscorpion
All,
On Monday, I had the pleasure, for the first time in about five years, to j=
oin my colleague, Russell Wyeth, on his entomology field trip with the stud=
ents of his invertebrate zoology class. The focus, because of the weather, =
was largely on the aquatic insects. We went to two sites, a brook and a pon=
d, sites which I have sampled extensively with my own students.
While helping a trio of students at the pond, one of them pointed to a subm=
erged log and said, "What is THAT?" I looked, I shuddered, I asked for (ok,=
demanded) a net, and caught the waterscorpion Nepa apiculata. We do have a=
much more common waterscorpion here, <http://bugguide.net/node/view/14962=
> Ranatra fusca, the Brown Waterscorpion but it's no issue at all to tell t=
he two apart. See http://people.stfx.ca/rlauff/personel/recent.html for a p=
icture of the one I caught.
Nepa is rather uncommon here, I know of specimens at DNR and the NSMNH, per=
haps five total. And given that I've been doing a lot of aquatic insect sam=
pling recently, including at Monday's pond, this was a very nice find. My t=
hanks to Hannah Stevens, the student who spotted the insect.
Randy
