Scarce Fungus Weevil - Platyrhinus resinosus


This is truly an odd looking creature and could hardly be confused with anything else, except perhaps the Platystomos species. The mix of dark and light areas on the elytra may vary, but the general appearance does not - the 'face' is always lighter due to a covering of pale hairs. Also known as the Cramp-ball Fungus Weevil.
