Tree cricket?? - Oecanthus laricis - female

Tree cricket?? - Oecanthus laricis - Female
Franklin, Oakland County, Michigan, USA
September 13, 2009
Is this another tree cricket? Adult? Female?

Moved from nigricornis group. Those dark brown femurs allow the ID as O. laricis.

Compared to O. pini which have green femurs, see here:

Moved from ID Request. Pending ID by Dr. Walker. Is either O. pini or O. laricis. The femurs are dark brown, which might make it O. laricis.

This may be a very important find, Hilma
There's a possibility that this is a Tamarack tree cricket - Oecanthus laricis. They are only known to occur in southern Michigan and northeastern Ohio -- on Tamarack and Hemlock trees.

Where did you find this tree cricket....and what type of tree did you find it on. If it was not on a tree, what trees are nearby?

I'm going to send a message to Dr. Thomas J. Walker to see what he thinks. If it is a Tamarack tree cricket -- I may be visiting your town soon! We need to get more recordings of the song of this species.

BTW, I too am a nurse. :)

Wow, and I almost didn't subm
Wow, and I almost didn't submit the photo...surprise, surprise. Actually, it was found over the top of my back door. However, our backyard is about 1/3 acre of woods with paths in it. We do have some hemlocks but I'm not sure about any tamaracks (larches). I do know that there is an absolute cacophony of cricket, cicadas, tree toads and more all day and night. Isn't this a happy surprise!

Dr. Walker has confirmed that it appears to be
a Tamarack tree cricket! Pine tree crickets and Tamarack tree crickets look remarkably similar -- but the Tamarack tree cricket has dark brown femurs; while the Pine has green with brown.

This is the first photo in the guide of O. laricis.

I'll send you a message re: need the song recorded.

Great find, Hilma!

tree cricket - yes
Looks like a male to me, with the width in the wings. I don't know the species though.
