A LEAFLIKE KATYDID
Here's the big katydid I found this week hanging on the Reserve's bathroom door and then transferred to the woods below:
You might enjoy seeing if you can spot how it differs from the "Common True Katydid" found in much of eastern North America, shown at http://bugguide.net/node/view/27886.
*UPDATE: Back in 2007 I couldn't be sure what species we had here. In 2024 when I'm reviewing my old pages, many more resources are available on the Internet, and our katydid appears to be STILPHNOCHLORA AZTECA, with no English name.
Stilphnochlora azteca occurs through most of upland Mexico, except in Baja, south through Costa Rica. Despite the large distribution area and the appearance of its name on many lists as present, I find little information about the species' life cycle, other than that it feeds on plant material and produces a distinctive call during the night.
