Ensign Wasp: Cockroach Egg Parasitoid Wasp

Waiting for me when I got back from a trip
This bug was on my desk when I got back from Denver. It is probably something very common and I am going to look silly for asking, but… what is it? Thanks,

Hi Daniel,
Because this question came from you, we could not rest until we had the answer. We believe this to be one of the Parasitoid Ensign Wasps, more specifically, the Cockroach Egg Parasitoid Wasp, Evania appendigaster, as evidenced by some images on BugGuide. According to a University of Florida website: “The female adult lays her eggs in the oothecae of cockroaches, parasitizing them. These insects, therefore, are beneficial to us.”
