Diploptera punctata

Diploptera punctata or the Pacific beetle cockroach is a species of cockroach in the family Blaberidae and subfamily Diplopterinae. It is one of the few cockroach species that is viviparous. Adults are chemically defended, having a modified tracheal gland and spiracle on each side which squirts quinones which can poison or discourage a predator. Diploptera punctata can be found in Australia, Myanmar, China, Fiji, Hawaii, and India. Diploptera punctata produces a nutritionally dense crystalline 'milk' to feed their live-born young.
