Leucospilapteryx omissella (Stainton, 1848)

mugwort slender

Leucospilapteryx omissella mines

Artemisia vulgaris, Nieuwendam

Leucospilapteryx omissella mines

A single leaf


Continuously new silk is deposited criss-cross in the mine, partly wrapping up the frass grains.

mine

Upper surface blotch, with a conspicuous yellow-orange tinge (older mines turn brown). The larva lines the inside with much silk, causing the mine to pucker op strongly (the inflated surface and mostly orange tinge distinguish the mine easily from the one of Calycomyza artemisiae on the same host plant). The mine is preceded by a long lower-surface corridor, running along the midrib or the leaf margin (but practically invisible because of the densely hairy leaf underside). When the larva is almost full-grown is starts eating parts of the upper epidermis, giving the older mines a mottled appearance. Black frass in the centre of the mine. Pupation external.
