Your letter to the bugman:  So, I had just got home and went to check the letter box when I saw this fly sitting on it. But it wasn’t just any fly! It had a strange pattern, opposite to a wasp’s and it had oval eyes, it also had a strange antenna that split into two at the end, it’s wings were a strange shape and were covered with orange and black fur. It had no stinger bus was similar in colours to a bee. And also it’s legs were slim but it’s body was wider. It didn’t move no matter how close I put my camera, which is ver strange. I’ve never seen a fly with thick fur, let alone an orange a black one! Please help me discover what this strange insect is, but also, it could be new!

Tachinid Fly

Dear Bethany,
We are presuming you are from Mount Helen, Montana.  We are feeling confident that this is a parasitoid Tachinid Fly, but we have not had any luck identifying it to the genus or species level.  According to BugGuide:  “Second largest dipteran family (after Tipulidae), with ~1350 spp. in >300 genera of 4 subfamilies in our area.”

Tachinid Fly

Actually I’m in Mt Helen, Victoria. Is it possible that the fly is a new species?

Dear Bethany,
Thanks for getting back to us, clarifying the original vague location information you provided for us.  Now that we have established your actual location, we have located this image on Diptera Info that is identified as ” Tachinidae –
Microtropesa sp. from western Australia.”  We have another member of the genus Microtropesa among the postings in our archives.  The genus is well represented on Atlas of Living Australia.

Thank you for the clarification, it looks a lot like what I saw
