Species of the Month

Cylisticus convexus (De Geer, 1778)

Cylisticus convexus is patchily distributed across Britain and Ireland where it occupies sparsely vegetated coastal habitats and man-made sites, such as old quarries and farm yards, inland.  It can be elusive, but may be numerous once a favoured spot is found. It readily rolls into a flattened ball when disturbed and could be mistaken for one of the pill woodlice Armadillidium sp.  However, it is readily distinguished by its pointed and projecting ‘tails’, which are often contrasting orange in colour.
