Armadillidium vulgare
Woodlice in the family Armadillidiidae are able to form their bodies into a ball shape, in a process known as conglobation. This behaviour is shared with pill millipedes (which are often confused with pill bugs[1]), armadillos and cuckoo wasps.[2] This behaviour may be triggered by stimuli such as vibrations or pressure, and is a key defence against predation; it may also reduce respiratory water losses
