    Life History

    Feeds on dead organic matter, which it detects by means of taste and smell. Mating tends to take place at night, and for this reason is very rarely observed. When a male finds a receptive female, he climbs onto her back and drums her with his front legs whilst 'licking' her head with his mouthparts.
