Rhinoceros roaches and the baby cycle

[Elytra and Antenna]

Rhinoceros roaches only have babies once a year around November Australia. In captivity they also only give birth once a year, not seldom once or twice in a lifetime even if the female lives eight or ten years total (total lifespan for some dozens and a few decades has been 7 to 14). Specimens kept in the Northern Hemisphere flip the cycle and only have young from April to around July 4th (after being in captivity a year or two. Imports would still give birth in November for the first year or two). When it's this late in the year if there are no babies the chances begin to appear very slim. Thrilled to see a decent group born the other morning.

Very non prolific species any pics of them or your baby’s ? They also grow very slow?

Yep, very limited reproduction is why one baby is usually a hundred bucks or so (also Macropanesthia is the heaviest blattodean on earth and while a big male is unbelievable even the runts are huge terrestrial arthropods). They do not grow slow if compared to large arachnids, myriapods, etc.
