Bee-eating beetle

Its larvae hatch inside solitary bee nests and eat the eggs and grubs of their hosts before pupating in the very cells they emptied.

Adults are hairy beetles with bright red elytra crossed by broad black bands, a shining blue black head, and a red apex reaching close to the wing tips.
