From a few scattered records the species breeds from late May to November in the Durham region. Specimens to 16 mm long are common. Porcellio laevis Latreille Figs. 24, 25 Porcellio laevis Latreille. Van Name 1936:229, fig. 129. Brimley 1938:502. Schultz 1961:194. In North Carolina this common, large species is collected almost exclusively around human habitations. It is rare in woods and other remote locations. In both the Durham region and at Beaufort it was taken almost exclusively near building foundations and in refuse heaps. North Carolina is probably the southern limit of its range, since it was.
