'The Bowtruckle is a peaceful and intensely shy creature...'

An extract from the textbook Fantastic Beasts and Where to Find Them

The Bowtruckle, which eats insects, is a peaceable and intensely shy creature but if the tree in which it lives is threatened, it has been known to leap down upon the woodcutter or tree-surgeon attempting to harm its home and gouge at their eyes with its long, sharp fingers. An offering of woodlice will placate the Bowtruckle long enough to let a witch or wizard remove wand-wood from its tree.
