Saluti,
# 2471 ♂ & 2472 ♀ at an altitude of ~ 920 m in Cne : La-Cluse-et-Mijoux (Dépt. Doubs) - 07.06.1992
- These ♂ and ♀ was copulating.
For the keys of determination of these sp., see : viewtopic.php?f=11&t=34877 & viewtopic.php?f=375&t=35433
Take care ! :
Only the color of the hairs on head, allows to differentiate the sp. ♂ bifasciata rossii & segmentaria.
But, we observe on our capture ♂ (is it specific ?) :
- The grey color of the apex of forewings does not penetrate into the median cells (it is the opposite for bifasciata rossii).
- This grey color is also more diffuse as for bifasciata rossii.

segmentaria è stato catturato anche in Italia
Ciao.
