... did drop in to visit.

She slept in the angle of the ceiling and wall above my desk for two days, then went about her business.

Drumming katydid, female*, Meconema thallassinum

These insects drum on leaves with their hind legs. And they hear their song with an organ that functions like our ears, with a membrane (the typanum) stretched over an air sac. Except that the "ear" is on the front leg, just below the knee.

Front leg, with tympanal organ.

"Do you mind if I drum on your wall?"

*The female has a long, pointed ovipositor at the end of the abdomen. The male has two curved pincer-like appendages instead.


  1. I met Mormon Crickets for the first time last weekend and the ovipositor really surprised me. They were all busy putting it to use

    I have never met a Katydid here in Puget Sound country.

  2. Very sharp picture - love the green color...

  3. Upupaepops; I don't think I've ever seen Mormon crickets, either.

    Susan; thanks! It's a marvelous, jewel-like green, isn't it?

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
