FORKED FUNGUS BEETLE
These unique beetles make undemanding and long-lived pets (as long as five years!) They live and feed on several species of shelf mushroom, completing their entire lifecycle on them.
 The males compete for mating rights using a set of horns which have a lot of natural variance within the species. The females lack these horns, making these beetles straightforward to sex. 
The mushrooms this species requires for food and to host their larvae are available through the website.
