The tutor brings up a species (two, actually) that are common here.

In BC, “wood bug” refers to either of two animals: the sow bug or else the pill bug. They are very similar, so here, they share the handle “wood bug”. However, the sow bug has two “tail appendages” – the pill bug doesn’t. Compared to the sow bug, the pill bug is rounder in shape, so able to roll into a tight ball for defensive purposes. I’d say that, around here, both are very common.

Interestingly, sow bugs and pill bugs are crustaceans: they are more similar to crayfish, crabs, or lobsters than to insects. They have seven pairs of legs. They eat, primarily, decaying plant material.

Being crustaceans, sow bugs and pill bugs need moisture. Therefore, they are found in damp, dark places, and are apparently more active at night. Conveniently, the same conditions that maintain moisture also promote decay.

Even pestcontrolcanada.com points out that sow bugs and pill bugs are helpful to the environment because they recycle nutrients – in some cases, even more beneficially than earthworms. University of Kentucky says that they are an eyesore, but really not a problem. Their presence indoors is symptomatic of a problem – wet conditions that foster decay.

I certainly don’t see wood bugs, as both sow bugs and pill bugs are called around here, as pests. They are benign recyclers of the tree material constantly raining down on us from the Douglas firs and others. Out in the yard so much lately, I’m noticing them when I move things, etc. Of course, this summer’s been quite damp: we’ve had rain most weeks.
