that of the beetle Orchestes
pilosus, but the mine of O. pilosus is darker and
smaller when mature. The frass of E.subpurella is also typically
'spaghetti' like in appearance (British
leafminers, as Eriocrania). The mine is aslo illustrated
in UKMoths
(as Eriocrania subpurpurella) and Nederlandse
bladmineerders.
Larva:
Larva white, head pale brown (British
leafminers (as Eriocrania subpurpurella)). The larva
is also iluustrated in Nederlandse
bladmineerders.
