Polymorphic vs Discoid Roach

Second Instar
Which one is a faster breeder? also wich one is the larger of the two.

Also, what is the fastest and largest breeding roach? Bigger then dubia.

 
At lower temps Dubia stop breeding altogether while Blaberus usually can reproduce well into the lower 70s but Dubia can breed a little faster at higher temps.

 
Dubia breed faster at optimal conditions. In my experience though dubia mature slower than discoid. Discoid are a bit larger than dubia.

 
Ive had Dubia, discoid, B. fusca, and E.posticus for my main feeder colony. E. Posticus are now my main colony. They have good size and good maturation rate for a larger roach and out produce the dubia and discoid colonies I had. B. Fusca are great too.. Dubia are good but IMO discoid, fusca , and posticus are all superior feeders...
