This species is less wary
and more sluggish than other common cockroaches. It may enter
the home in food packages and laundry, or merely come in under
the door or through air ducts or ventilators. It's common in
sewers, utility chases, in dark, damp basements, and is known
to climb water pipes to upper floors in blocks of flats. This
is a notably gregarious species, commonly being found in large
colonies.
A few facts :-
1.They are 25-30mm long.
2.They are dark brown to black.
3.Wings are undeveloped in the female, and only cover 3/4
of the length of the abdomen in the male, this can be seen
in the picture below.
4.The female will produce 5-10 oothecae (egg cases) in her
life time.
5.There are 16 eggs inside the egg case (Oothecae). Phew.!
imagine if all that lot survived.
6.The hatching time of the eggs is about 2 months.
The nymph, when it hatches, will moult up to 10 times before
it reaches adulthood.
7.The development of the nymph can take up to 9 months, but
can be as little as 5 months, then they too are off laying.
