Your letter to the bugman: We found this bug in class. I suspect that it’s some kind of wasp. Please help me identify it.
How you want your letter signed: Juan Espinoza
This is a Wasp Moth, but we have not been able to identify the species. We will see if Arctiinae expert Julian Donahue can assist with a genus or species identification.
Thank you for your response! I’ll be waiting to hear from you about the moth wasp.
Update: Julian Donahue responds.
It’s a species of Macrocneme. Quite a few species in the genus, very similar in appearance, but separable by genitalia. In fact, the key to species in the revision of the genus by Dietz in 1994 is based on male genitalia!
The current classification is now: Lepidoptera: Erebidae: Arctiinae: Arctiini: Euchromiina: Macrocneme.
My, how they’ve demoted the ctenuchids!
Anxiously awaiting the onset of the monsoon,
