Mixed copula's don't necessarily lead to hybrids of course, but indeed hybrids in butterflies do exist and hybridization is for example well known in Swallowtail and Corsican swallowtail. Another well know example is Erebia 'serotina', once described in the Pyrenees as a species on it's own but in f...

Common blues of N-Africa (and locally in S-Europe) have recently been split off as Polyommatus celina: http://www.biodiversidadvirtual.com/tax ... ticulo.pdf

I don't see any black in the (much abraded) fringe and the little bit of blue from the upperside you can see seems to have a little bit of a purplish hue, so I think this is a "common blue". In Tunisia this should be Polyommatus celina, recently split off of Polyommatus icarus and replacin...

All pictures show brimstones, second one is a male. The Loire region is just a bit too much to the NW for cleopatra.

Hope this can help: Euphydryas cynthia

In 2015 there has been already 8 confirmed sightings in the Netherlands, Belgium has to do with only one in 2015 for now

For France I use the following website a lot. http://inpn.mnhn.fr/accueil/index In the right search bar you can search on species so you can get on the species page. End of june for example is perfect to search for Erebia meolans. http://inpn.mnhn.fr/espece/cd_nom/647125 Then click on the left side ...

Hi all,

hopefully I find the time to keep it updated regularly...

hope you enjoy

Thanks for the reference, Guy :) I have no experience with M. britomartis but I have experience with M. athalia and a little with M. aurelia, especially in Belgium where the first one is locally common in the centre and south of the country (but lacking in the extreme south) and the latter is rare w...

Keep in mind these recent findings...

Hi all, Taxonomy in the genus Hipparchia isn't straightforward and literature is not easily found on the net. So I wanted a place to ask some questions, hence this forum topic. My first question: In Sicily 2 taxa of 'orange' Hipparchia occur, Hipparchia blachieri (former subspecies of Hipparchia ari...

There is a second hand over here. Reference : LIO7432

No doubt about Adonis - Polyommatus bellargus

Is there a Friesland (northern Netherlands) equivalent fenny race to our britannicus ? I ask because it might have evolved when the North Sea was dry land but at the end of the last Ice Age, the populations became isolated. If there is a Dutch fenland race, then conceivably vagrants of this race mi...
