Bioblitz Species Hunt

by Carl Strang

Yesterday I introduced last weekend’s bioblitz at Connor Prairie in Indiana. My focus as a bioblitz participant is on singing insects, of course, but those are few early in June, even as far south as Indianapolis. Not to worry, though. There were teams focusing on many groups of organisms, but others had no specialists to address them, so I enjoyed filling in where I could. Odonata were one such group.

After much pondering, I concluded this was a female cobra clubtail. Indiana has a similar species, the handsome clubtail, but certain details ruled it out.

For instance, the C-shaped line at the top of the side of the thorax is connected, and apparently too thick for a handsome clubtail.

I also saw three bumblebee species.

Bombus fervidus was an easy ID.

There was a butterfly team, but I took advantage of photo ops that presented themselves.

Nevertheless, my main interest was singing insects. I found 4 species, and botany team leader Scott Namestnik added a 5th.

Green-striped grasshoppers were common, as were spring field crickets.

I saw a single sulfur-winged grasshopper. Scott ran across a pocket of Roesel’s katydid nymphs. Connor Prairie is about even with the Crawfordsville area where I found Roesel’s a couple years ago. So far, none have turned up farther south in Indiana.

The final species is worth a blog post all its own (to be continued).
