Pill beetles can retract all their appendages into ventral body grooves-so feigning death and are then said to resemble or mimic a rabbit dropping or seed.

Both larvae and adults feed on moss, algae and liverworts.

Main habitats include moorland, heathland and sandy shorelines.

They are found beneath logs and stones and at plant roots on damp, sandy or stony soils.

[2][3] They form part of the diet of the Red Kite in Wales [4] and have been found in Kestrel and Little Owl pellets.
