Chrysoclista linneella, (common names include Linnaeus's spangle-wing, linden bark borer and cosmet) is a moth of the family Agonoxenidae found in Europe and North America.

The wing pattern consists of three round, warty, silvery shiny spots.

The first spot has a tuft of protruding, black-brown scales and is located at 1/3 of the inner edge of the forewing.

The anellus lobes are distally strongly dilated and have a subapical semicircular indentation inside; the apex is toothed.

Older records on beech (Fagus) and apple trees (Malus) require confirmation.

The caterpillars live from August to May in feeding tunnels and round chambers under the bark of tree trunks.

The infestation can be recognized by the light brown caterpillar droppings, which appear in bark cracks.

Often, on the other hand, they are found in large numbers in cities with lime tree avenues It is found in most of Europe..[3] Content in this edit is translated from the existing German Wikipedia article at de:Chrysoclista linneella; see its history for attribution.
