Teleiopsis diffinis (Haworth, 1828)

large groundling

on Rumex


The young larva makes a slender sinuous gallery with only here and there some frass. Sometimes the mine is widened near the leaf margin into a blotch. The larva may make several mines. Older larvae live free at the underside of a near-ground leaf in with silk a more or less tubular contracted margin, often causing window feeding.
Bland ao do not write about a mine; perhaps it is not made in all cases.
