I think this may be Lulworth skipper, Thymelicus acteon.
Look at the size and shape of the sex brand, and the darker colouring at the outer edge of the forewing topsides.
(orange/brown underside to tips o antennae is OK)
I know it is not in all the lists of Italian butterflies, but it is here
"Thymelicus acteon (Rottemburg, 1775) (N, S, Si)"
it's my fault, sorry. I didn't look to the italian checklist, just look on the UK Butterfly site, most of the times the subject is not on the checklist because they are not update.
Yes, I agree with you, I thought the darker colouring at the outer edge was just a colour variation!
Thanks Mike, always fast and accurate
Sorry to throw a spanner - my email server has been very tardy recently and I've just caught up with this discussion.
This looks to me more like a large skipper, going simply on the sex brand. I have two guides, one which has photos and the Collins with drawings. In both, the Lulworth sex brand is shown as thin and wavy while the Large skipper's sex brand is a broader gash like in this photo. I'm looking particularly at the third photo. Any thoughts?
I'm sorry but I couldn't help you, I'm no so expert in Lepidoptera.
I thought the sex brand was so marked only in the T. lineola, T. sylvestris and T. acteon, and the darker colouring at the outer edge of the forewing topsides only in the T. acteon.
Thanks, I'll wait ...
Here a shot with the closed wing of my subject and a Large skipper from the UK butterflies site:
This is my subject.
This is the Large skipper from the UK butterflies site.
the lower part of the hind wings is different.
I'm not over-reliant on the UKButterflies website as it is specific to UK and butterflies that have a Europe-wide range can often have a different appearance 1000 miles away.
So here is a photo of a large skipper from this German website
I think this is very similar to your third photo in your original posting.
Yes Alan, I think you'r right, there is difference from Country to Country because of the biodiversity, here is a shot from Italy (Pavia) near to me, from the Treknature site:
This is the Large skipper from the Treknature site.
BTW my knowledge of this Genus does not go beyond this, better to wait Mike ...
You have pictured my assessment exactly: the large skipper undersides consistenly show a faint patterning, whereas the Lulworth skipper undersides are consistently plain.
I know what you mean about the large skipper's sex brand, but to me the other markings make a clear distinction: the Lulworth skipper has a plainer darker border, whereas that of the large skipper is more mottled.
I understand your concern about the patterning but something is anomalous here. Either the sex brand is far to wide for the Lulworth or the underside is apparently too plain for the Large. I've made an extensive search on the Internet (butterfly sites only - flikr etc can hold loads of misidentified stuff) for a Lulworth with a broad sex brand as in the specimen under discussion and I couldn't find one. Maybe you can. So I searched instead for a large with a plain underside and found this:
My money is on the Large Skipper.
So can we confirm that it's the Large skipper / Ochlodes sylvanus male?
It was not easy, and I still have some doubt, but it's ok, I'm a bit confused because I'm not so expert
Thanks to Mike and Alan for all this work!
