Species of cockroach
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
Diploptera punctata has 4 nymph stages, which are wingless. The adult is winged, and the adult male is smaller than the female.
[3]
Distribution
Diploptera punctata can be found in
Australia ,
Myanmar ,
China ,
Fiji ,
Hawaii , and
India .
Milk
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 .
