dorsal view


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 and also is a darker yellow in colour. 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
