@All About Insects Congrats on the 15 new babies, that should help turn around the species for you too. Funny to hear of two males hiding out in the substrate, apparently it was a good thing to check those lumps. :)

Speaking of your Parcoblatta pennsylvanica species molting to adulthood, how long did it take them? I've read that the nymphs take 10 months to 2 years to molt to adulthood.

Thanks, it definitely should! Yea, it was.LOL Non-coincidently they were right next the females.

When I collected them they already were only around three molts from adulthood, so I'm not sure how long it took in total from hatchling to adult, but my first one matured almost exactly two months after their collection. :)

Best of luck with them. That makes sense the males hiding next to the females. ;)

Ah okay, I was just curious as they seem to be very slow growers.

They're relatively slow for roaches, but 2 years is definitely far fetched. If they averaged about 1.5 molts per moth in my care(keep in mind that there are larger gaps between molts in the older instars, just like with mantids, of course) then I would estimate that the average time from hatchling to adult would be around six to seven moths in captivity, likely a couple more months in the wild.

Some good data there for the captive species and makes the obvious conclusion that the referenced information is for wild specimens, and likely errors too much on the time span needed. Thank you for the informative response.

Even with the shorter time span the species though is still not suitable as a feeder, which was my original interpretation when researching them. I found some specimens originally during my isopod collecting trips and due to their near zero chance of a infestation was hoping I found a roach I could win the battle with my wife with. Alas it is however not to be, and crickets continue ruling as my primarily feeder. ;)

No problem, I'm glad you found it informative. 

Yea, only one species of Parcoblatta can be used as a reliable feeder, that being P.fulvescens.
