Stonefly on my screen door

[Night_Stalker]

The insects like to collect at night at the front porch lights (Conodoguinet, Camp Hill). It is a good way to know what is active.

This Stonefly was at the photographed 2 nights ago. About 1.125" from nose to tip of wing.

I saw a bright yellow one with clear wings several weeks ago in the state college area. It was the same size.

It's better to measure insects in mm. All the published material on insects list length in mm.
