Most are black with metallic, coppery-orange segments. They have long bodies but have very short wing cases (elytra), which makes them look a bit like earwigs without the pincers.
They have the ability to wave their abdomen around and often curve it upwards. This is thought to be a defensive tactic.
Whilst they don’t bite or sting, their body fluids contain a very poisonous toxin which can cause extremely painful skin irritations.
Adult size: 7-9 mm
