< back
head - dorsal view
head - dorsal view


Food Plant: Salix (willow)

Mine: late Summer

Notes: Forms circular blotch mines on the upper surface of the leaf . There are two species in Britain and both are uncommon. I. foliorum has become very scare, though widely distributed, whereas I. sequensi, a recent colonist (?) seems to be spreading slowly, but recorded only from SE and E England. The life histories are not known in sufficient detail to identify these species either from the mine or larvae. The pupal head detail in dorsal view is shown.

Synonymy: I.populicola

Data: 29.ix.2007, ex mine 12.ix.2007, Fleet, Hants, VC12
