La Serpette

Wingspan: 20-28mm

A bivoltine species flying from April to September when it is attracted to light but males can also be seen flying in sunshine in the canopy of beech trees. It has been recorded at Las Descargues and Ladirat but none of the lower sites.

Larvae feed on Fagus sylvatica before overwintering as pupae in cocoons within beech leaves.
