Bucculatrix thoracella (Thunberg, 1794)

Wingspan: 6-8mm

A bivoltine species appearing in June and August when it flies in evening sun but later comes to light. Yet to be recorded as an adult at Las Descargues although mines have been recorded in the valleys surrounding the plateau.

Eggs are laid on the underside of leaves of Tilia species with the larva forming a hook-like gallery eventually producing a window in the leaf away from any veins. Pupation takes place in a cocoon on the trunk of the parent tree or in leaf detritus beneath.
