Thanks Malcolm, bayucca and Daniele for your interest in this moth. Checking my next pictures to identify I found a Pirgus sp. or chequered skipper so it will be my next spotting.
Thanks for the ID, Manval
Good job, maniacval :-)... GebänderterBesenginsterspanner is German ;-)
Sorry common name: Frosted Broom (English), Fidonie du genêt (France) and Gebänderter Besenginsterspanner (Dutch). Reference: http://www.lepidoptera.eu Greets
Translations of French and German common names suggest this could be called Broom Moth or Banded Broom Moth.
Hi guys Easy ;); thank you very much Daniele for this nickname of moths maniacs (lol). Take this link for look more pics the this mot: http://www.biodiversidadvirtual.org/insectarium/Isturgia-famula-%28Esper-1787%29.-cat10322.html Greets
I agree with bayucca and arlanda. I can see why you're raising the issue Malcolm: on the second shot for instance you could almost think the antennas are slightly clubbed. All members of the Pyrgus genus have clearly prominent downward bent antenna clubs, and none are a match on other features. One for the moths maniacs :-) Maybe Manval?
Definitely a moth any most probably a tough one!
Thanks Malcolm. I have been considering that possibility, but it does not fit completely OK to me, I never get a complete match. Specially the antennae. All the skippers (and all rhopalocera) have clubbed antennae but this specimen lacks the club end. Thats why I think it could be a moth. I am scanning the Geometridae family to find a better match but it is a huge family
Hi arlanda, I think this is a butterfly, one of the skippers, maybe Pyrgus Genus. Check with bayucca or Daniele.
