On behalf of Pterry, thanks so much for all the comments and links! Just a couple of responses:

Two Dishes – It’s “Mr.,” actually. The sexual organs are quite obvious and distinct; the female’s looks like a long spear. And only the males stridulate.

Julie – The latest issue of Audubon included an excerpt from that book. Sobering stuff! Very much the sort of thing I like to ponder myself. (I tried to leave a comment at your blog to that effect, but then noticed you had comments restricted to Blogger users.)

We have DSL back this morning. I’m keeping my fingers crossed.
