Food Plant: Alnus glutinosa (Alder)

Egg: Underside of leaf

Mine: July, September - October

Notes: A narrow gallery with frass in thin central line. The larva is a pale yellow, head pale brown. The moths must be bred through to identify S.alnetella and S.glutinosae. The larva of S.alnetella can be distinguished from that of S.glutinosae as glutinosae has a pale brown rectangular plate on the ventral surface of the prothorax. The ventral view of the larva is the middle photo above and there is no plate on the prothorax.

Data: 19.x.2006, Fleet, Hants, VC12
