Distribution: Found worldwide in decaying vegetaion.

Habitat: Moist underside of decaying material. Common in mulched gardens, under rotting logs.

Field Notes: Not an insect but a crustacean, these creatures take about one year to mature, live for abut three years and breed once or twice a year, depending on climate. Often found with slaters, millipedes and centipedes. The most distinguishing feature of the pill bugs (and the unrelated pill millipede) is its ability to roll into a tight ball, presenting its hard plates to any would be predator. Seven pairs of legs and one pair of antennae. Less than about two centimeters.

Uses Pill bugs are edible, as are many crustaceans. However, pill bugs strongly resemble pill millipedes, which secrete noxious substances and may be toxic. If unsure then do not eat. Some of the common names also refer to other similar organisms.
