Thistle Tortoise Beetle

Cassida rubiginosa


Over all length 6 - 8mm. The scutellum and elytra are flattened at their margins to rest on the leaf surface so that no shadow is given, so helping to disguise the beetle's presence. The main colour is green with some dark marks where the scutellum and elytra meet.


Meadows and rough grassland where thistles or other Asteraceae can be found. The larvae feed on the leaf surface and put their own excrement on their backs for camouflage.
