As an experienced animal keeper, I’m here to show you that sow bugs, and isopods in general, are much more than just mindless garden pests!

What Are Sow Bugs?

Sow bugs, often referred to as just “woodlouse” or commonly confused with “pill bugs,” are actually not insects at all, but crustaceans!

They belong to the family Porcellionidae and they are of the scientific species Porcellio.

The common name “sow bug” comes from their resemblance to the similar-looking pig species known as swine, when viewing either from the top down.

Found all over the world, they live in moist, decaying vegetation found primarily in gardens, forests, and leaf litter.

Sow bugs are omnivorous, meaning they feed off both plants and other small organisms.
