Porcellio succinctus
A broad, large woodlouse of limestone country in southern Spain. About 28mm of body plus long antennae and uropods make it imposing. Needs low humidity and airflow, produces few young and dislikes change during the summer breeding season, so it suits advanced keepers.
Porcellio succinctus, described by Budde-Lund in 1885, comes from limestone areas of southern Spain. The stocky body is about 28mm long and 15mm wide, and in males the antennae and uropods each add about 15mm, giving a total length of over 50mm. A dark ground carries white segment edges and white dorsal markings, and a strongly white-skirted 'Black Ribs' line is traded; juveniles are almost white with only a few black dots. As a limestone species it needs generous lime in the substrate, limestone hides and permanent cuttlebone. Outside the breeding season it tolerates 16-30C, but in summer, when breeding occurs, females are sensitive to any change, and each produces only 10-20 young a year, so building a colony takes time and stable management. It also suffers under summer heat.
