Sardinia, approx 10km West of Cagliari, 100m elevation. 31st March 2011.
Ruderal area near exposed sand/shingle river bed through woodland, on yellow crucifer flowers. size approx 8mm.
Initially this doesn't look very Phasiine, but it is - note the slightly reclinate ocellar bristles and 2 widely spaced ia bristles.
I think this is a male of
Dionaea and that the species is probably
aurifrons, which is listed by Cerretti for Sardinia.
The other possibility is
magnifrons, which maybe Theo can completely discount.

I've never seen a
Dionaea but it's obviously a very interesting fly - well done! :D

Sorry, guys, I have little if any experience with Dionea.
I guess the genus is OK. It surprised me at first sight as well, but Dionea indeed is rather non-Phasiinae.

I suppose the next question is ... did Steve catch a few spares? :D

Nope, sorry, only this one. I know it is quite rare in Northern Europe, with a few records for the UK, but I thought it wasn't too difficult to find around the Mediterranean. This is the first post for
Dionaea on diptera.info though:)

I asked Peter Tschorsnig for his opinion on the species. His reply was
"
I would guess Dionaea aurifrons because the frontal vitta is only slightly narrower than the parafrontal."
