Sexing Phileurus truncatus, as well as breeding.

The genus Phileurus have proven quite troublesome for some people, and it really is a shame this large long lived species isn't as common in the hobby.

As can be seen with the pictures, with regards to this species (and genus), males have a very "square" last segment, unlike the females, whose last segment is more triangular.

Breeding them is rather unique, one must keep them either by pairs or just in single mated females. They will not lay if two females are in the same breeding bin.

Adults do eat each other (they are predatory), so be sure to keep up on feeding. Males can be kept alone after pairing.

They can be fed wet dogfood, but a diet of beetle grubs works well as well! They will also eat roaches and crickets if they are injured before feeding.

Breeding bins should have a substrate of 7 inches, they not do well on raised bed soil, so flake must be used.

Larvae are communal and make a cute buzzing noise when held. Adult females do eat their larvae and thus larvae should be removed from the breeding bins frequently.
