I live in northern Illinois and found this guy outside this morning. It is maybe about an inch long, greenish grey, and long wings. Any ideas?

Spring Fishfly

Hi Stacy,
You must live near a source of water.  This is a Stonefly in the order Plecoptera, but we are uncertain of the species.  See BugGuide for more information on Stoneflies.

Thanks so much!  Yes, there is a marshy area across the street.  The weather up where we are has been unusually cold, so I think he was sunning himself on our house for a good part of the day.  I looked up the info on a Stonefly and for sure, it’s a match!  Thanks for the info and the quick response.  I appreciate it.

Thanks to a comment from Joshua, we are admitting that in a hurry we misidentified this Fishfly, mistaking it for a Stonefly.  See BugGuide for a matching image of a female Spring Fishfly,
Chauliodes rastricornis.

    I wouldn’t say stonefly, check out Fishflies, genus Chauliodes in Megaloptera.

      Thanks for the correction. That will teach us to be more careful when postdating over thirty letters in a short period of time. We got a bit careless.
