4.008 Stigmella glutinosae (Stainton, 1858)
< back


Food Plant: Alnus glutinosa (Alder)

Egg: Underside of leaf

Mine: July, September - October

Notes: A gallery with frass partly dispersed, but sometimes in a thin line (as S.alnetella). The moths must be bred through to distinguish between this and S.alnetella. The larva has a brown head and a pale brown rectangular plate on the ventral surface of the prothorax (as shown). It is a darker yellow than the larva of S.alnetella and this larva also lacks the distinctive prothoracic spot of S.glutinosae.

Data: 20.ix.2015, Hull, South-east Yorkshire, VC61
