The hindwing scales will help to separate some Eriocrania as will the antennae length, but genitalia dissection is best.
 
Habitat
 
 
Recorders' notes
Best distinguished from other Eriocrania by the tenanted leaf mine. In E sangii the larva is dark grey, almost black, whereas in E semipurpurella the larva is pale, rather creamy with a pale brown head. Hold the leaf up to the sun and the larvae are easy to see.
