The Bowtruckle was a hand-sized, insect-eating, tree dwelling magical beast with long sharp fingers (two on each hand), brown eyes, and a general appearance of a flat-faced stick figure made of bark and twigs, which served well as camouflage in its natural habitat.^[2] They were immensely difficult to spot.

The Bowtruckle could be found in western England, southern Germany, and certain Scandinavian forests. A Bowtruckle served as a tree guardian for its home tree, which was usually a tree whose wood was of wand quality^[3][4] (such as a Wiggentree).^[5] The twig-like fingers were well adapted for digging out wood lice in trees and could also be used as a weapon against a foe when aimed at the eyes.^[2]

A group of Bowtruckles was called a branch.^[6]

It was generally a peaceful creature, but it may attempt to gouge out an attacker's eyes if anything threatened its tree or itself, and was adept at dodging most types of charms.^[7] In order to take leaves or wood from a Bowtruckle's tree one would have to offer it wood lice or fairy eggs as a distraction.^[2
