Reproductive Biology

Reproduction is cyclical and triggered by environmental factors, such as rising temperatures and longer days. In addition, females experience an acceleration of ovarian maturation in the presence of males, although this effect is lessened in northern climates. Mating occurs immediately before the parturitional molt, usually from late spring to early summer, but sometimes the period extends from late winter to early fall. Females in northern populations have one brood per year, and those in

southern populations typically have two, sometimes three. Broods can include more than 100 eggs, but typically approximately one half of eggs develop into mancas. Eggs move into a brooding pouch, or marsupium. These woodlice can store sperm, which remains viable for approximately one year.

CONSERVATION STATUS Not listed by the IUCN.
