Trypeta immaculata (Macquart, 1835)
Pilosella officinarum, Belgium, prov. Antwerp, Meerhout © Carina Van Steenwinkel
leaf lighted from behind
The mine begins with a very narrow full depth corridor, that ends upon the midrib. Subsequently a broad corridor, or rather an elongated blotch, is made, often overlying the midrib; from here broad, lobe-like extensions are made into the blade. Frass in discrete grains. Secondary feeding lines conspicuous. The larva is capable of leaving the mine and restarting in a new leaf, in which case the association with the midrib may be lost. Pupation after vacation of the mine.
