What are the biggest hisser species?

[Blaberus Craniifer]

What kinds of hissing cockroaches tend to get the biggest and how big do they get? I am asking because I would like to hybridize them in the future to make a larger hissing cockroach. And yes, I will be very responsible about it.

Gromphadorhina oblogonata are the largest hisser species, not sure which is second largest though.

Do you know how big they usually get?

On kyles site he says Oblogonata get 80mm males max and if your gonna use a gromphadorhina, Gromphadorhina grandidieri would be the 2nd at 70mm.

Please don't hybridize them, that genus is already a mess. You could try selecting for the largest individuals in your colony and breeding those lines though. You should be able to get some pretty good sized hissers that way and you don't have to worry about potential low quality hybrid vigor.

Don't worry, this will probably never actually happen (at least not with me). I would prefer not to hybridize with tiger hissers anyways. I do not have an actual colony of hissers and I am fairly sure that the three females that I have are hybrids of some kind (maybe they aren't but I don't know) so I would like to get a colony of pure Gromphadorhina oblogonata and will definitely partake in selective breeding just as I plan to do with my Blabberus Craniifer once they reach adulthood.

Fair enough! I'd guess your 3 females probably are hybrids, but there's a small chance they could be pure line. I think it'd be really neat to get selectively bred giant oblongonota!
