Malacosoma neustria

The lackey

Lackey moth caterpillars live together inside a shared silk tent on the host tree, enlarging it as they grow until they scatter to pupate alone.

The lackey is a fairly uniform light to mid brown moth with darker cross lines and paler, sometimes creamy white hindwings, with a wingspan that ranges from about 26 to 44 mm depending on sex. Its caterpillars look nothing like the plain adult, striped in orange, white and blue over a dark body.

Caterpillars live together inside a shared silk tent spun over the host plant, enlarging it as they grow and feeding on oak, hawthorn, blackthorn and fruit trees before dispersing to pupate alone. The single generation of night flying adults favours woodland edges, hedgerows and scrubby grassland.
