A very rare and local species in Belgium. Study of the genitalia is sometimes necessary to identify the specimens, especially when they are worn.
Pinkish grey, paler laterally; head capsule and prothoracic plate dark chestnut brown; meso- and metathorax each with a shiny brown subtriangular plate on each side of the mid-line.
An oval case made by folding and spinning a piece of dead leaf.
The caterpillar probably needs two years to reach its full-grown stage. It feeds from a portable case made from folded leaf fragments. It can turn around in the case and move in both directions. Cases are mainly found within the vegetation around trees.
The adults come to light, but can sometimes be found on the wing during daytime. Males have been observed swarming around a female just before dawn.
One generation a year: from mid May till the end of July.
The larvae feed on dead and decaying leaves.
Dry, open deciduous and mixed forests.
