Warty pill-bug
Sphaeroma terebrans
Family Sphaeromatidae

8-10 mm

These pill-bugs can cause substantial damage to softer wood because of their habit of boring into softer wood. Many honey-combed pieces of wood are caused by them. These pill-bugs do not actually feed on wood but use it only as a home. They are actually filter feeders.

The related Mangrove gribble (Limnoria spp. Family Limnoriidae) on the other hand, prefers harder wood, actually feeds on wood and can cuase great damage to man-made structures like ships and pillars.
