I think I may have been skipped when I post this earlier. I found this bug on my sliding glass door and when I opened the door to get a closer look it flew off and landed on the wall where I then snapped a quick picture. I am new to the area and I am not sure what type of bug this is. It looks like a combo of a moth/wasp.

Ichneumon: Thyreodon atricolor

Hi Taylor,
It didn’t take us too long to correctly identify this parasitic Ichneumon Wasp as
Thyreodon atricolor by using the browse feature on BugGuide which states:  “Although most members of the huge family Ichneumonidae are difficult to identify, this large species is an easily recognized, day active, slow flying parasitoid of sphinx moth caterpillars.”
