No doubts, Trypeta immaculata and certainly not Rhagoletis alternata, even from details of wing pattern.

Thank you Valery. I agree about not Rhagoletis alternata; my doubt was about Rhagoletis meigenii, whose wing patter should match better. Can you tell me where to find a good key for the two genera?
Best regards, Carlo |

In fact, the best is the key by Merz (1994) -- Swiss Keys, which covers N Italy as well. The easiest characters to tell immaculata vs meigenii is the rounded / sharp antennal flagellomere 1 and stigmatal crossband very wide at posterior wing margin and fused with the next one to form a "hook" / not so, not reaching posterior margin and separated from the preapical band. Let me know if you need a pdf of Merz (1994). Edited by Nosferatumyia on 17-02-2017 23:37 Val |
