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.

"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. |

No, I don't torture 'em, I just photograph 'em. Large ventilated tank, cold LED lamp for focusing, studio flash.
