The European nightcrawler is a medium-sized earthworm, blue-pink and grey with stripes and a pale yellow tail tip. It wriggles through rich garden soil and piles of old leaves. It is a hard worker that turns rotting leaves into new soil.

Fun fact: this one is not an insect at all, it has no legs! But kids find it on every bug hunt, so it lives in Bug Wiki too.
