What's That Bug? does not endorse extermination

Subject: Huge katydid

Found in women’s bathroom (not by me!) at zipline facility (SkyAdventure) near Arenal National Park, Costa Rica (elevation approx. 600 meters, Caribbean slope). The body was about 4 inches; total length about 12 inches including antennae. I couldn’t find a good resource online, but a few somewhat similar images I stumbled onto were labelled as either Acanthodiphrus or Haemodiasma.
Thanks.

Hi Ben,
We have a photo of a Moss Mimic Katydid,
Haemodiasma tessellata, from Costa Rica in our archives, and Piotr Naskrecki who identified it states:  “often found in mid- to high elevation forests. They sometimes fly to light at night” which explains its presence in the women’s bathroom.  Piotr is currently on expedition in Mozambique, but we will attempt to contact him for verification.  A photo on FlickR looks nearly identical to your individual.

Piotr Naskrecki Responds
Hi Daniel,
This pretty katydid is Championica montana (Pseudophyllinae), a fairly common species in lowland to mid-elevation forests of Costa Rica and Panama.
Cheers,
Piotr

Ed. Note:
See Natural Visions and Master File for additional photos of
Championica montana.

Thanks!  And thanks to Piotr.  I have some books on order (or interlibrary loan) that I hope will help me with the Lepidoptera, but this gorgeous monster had me stumped.
