Male Dobsonfly Photo
After reviewing your site, I quickly descovered that this is a male Dobsonfly. I was surprised to find it on next to my front door this morning. I live in Robertsville, MO and I see bugs all the time, but this one is new to me. Have these been common in Missouri, or are they relocating in the changing climate?
Dobsonflies are local for your part of the country, but they are dependant upon a nearby water source. Year to year normal climate changes do affect yearly insect populations.
