Haven't a clue. But there are some really neat images in the Flikr
sequence. I particularly liked the hummer sequence, and the close macros
of some of the bugs.
To change the topic: The lemon meringue pie made me hungry:

"Small insects rely almost exclusively on passive diffusion and physical
activity for the movement of gasses within the tracheal system. However,
larger insects may require active ventilation of the tracheal system
(especially when active or under heat stress). They accomplish this by
opening some spiracles and closing others while using abdominal muscles
to alternately expand and contract body volume."

That's copied from Wikipedia. Seems like a good explanation to me. I
wonder if the katydid was in a jar or under lighting which was making
things warm.

Thanks for taking time to reply. No, I don't torture 'em, I just
photograph 'em. Large ventilated tank, cold LED lamp for focusing,
studio flash. Released unharmed!
