Hello Mr. Bugman!
I am so happy to have found your website. I am often curious as to what kind of bug I’ve found and now there is a resource! I have here a picture I took at Cala Lodge in Monteverde, Costa Rica last month. This huge grasshopper looked like he would camouflage very well in a tree. Helooked like he had a piece of leaf sticking out of his neck. Can you tell me what kind of grasshopper this is?
Thanking you in advance for your time,

Dear Lise,
This is NOT a Grasshopper.  It is a Katydid.  We believe it is a Moss Mimic Katydid,
Haemodiasma tessellata, a highland species that is already pictured on our site, or a closely related species in the same genus.  We noticed you have three additional identification requests, all titled as Katydids.  We did not look at the images yet.  If they are in fact all Katydids, we will attempt to get Katydid expert Piotr Naskrecki to verify our identifications when they are all posted.

Hi Daniel,
Yes, the big, mossy katydid is Haemodiasma tessellata.

That’s excellent!  Thank you for taking the time to look into this photo.  A moss mimic katydid.  How cool is that!?  🙂  I can’t wait to go back to Costa Rica.  I plan to pay way more attention to the insects there next time.  So different from what we have here in northern Canada.
Thanks again,
