Calm down Clark sounds like you are getting excited ! Barry looks like a Tachinid of some sp , I have reared similar species from beetle larva Genus Novapus here in nth Queensland . I think Dipterists must be an endangered species or simply too busy to comment . Some interesting stalk eyed flies about .
Yep , we get them up in the north here as well Barry , I sent some to the museum and they said great to have some records of hosts for these flies finally . Besides rearing them from Novapus in the Eucalypt forest I see them sitting around on logs in the rainforest as well.
