Diploptera punctata, the Pacific beetle cockroach, is a species of cockroach in the family Blaberidae and subfamily Diplopterinae.[1] 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.[2]
Life stages
[edit | edit source]Diploptera punctata has 4 nymph stages, which are wingless. The adult is winged, and the adult male is smaller than the female.[3]
Distribution
[edit | edit source]Diploptera punctata can be found in Australia, Myanmar, China, Fiji, Hawaii, and India.
Milk
[edit | edit source]Diploptera punctata produces a nutritionally dense crystalline "milk"[4] to feed their live-born young.[5][6][7][8]
The milk produced by Diploptera punctata is composed of hydrosoluble proteins and provides essential amino acids to the developing embryo such as lysine, leucine and valine.[9]
