Moved from Robber Flies.
Thanks, Herschel! Would this one be a female?

 
I thought
from some other shots that the male was the yellowish one but I believe looking at the very few shots here this is a male terminus. I will check Jeff's paper and see if he commented on coloration.

Yep, Jeff says the male is white, female yellow banded. Only IA specimens were from Delaware and Story counties. In the 1920s and 30s!

 
Great!
I've made the edit to indicate the gender.

Very nice
This is Ceraturgus cruciatus. Not photographed in IA previously I believe. Though recorded. Much less common than the species fasciatus in the NE and this genus in general is still a prize for any insect photographer anywhere.
