I have no male dubias?

[elly]

I've been trying to get my dubias to breed and I haven't gotten the temperature quite hot enough but I also have seen pictures that show the males with wings. None of my roaches have wings although some of them have reached an inch in length. Are they still immature or did I get stuck with no males?

Well I feel like the females would be larger than an inch (I saw huge 0nes at petco) so I would say that you have immature ones

Huh. Looks like I was wrong

Okay, thanks. They may be one inch long but judging from that comparison picture they all look like juveniles to me. You'd think they would have matured in the six months I've had them.

They take longer to mature if they aren't kept at 'optimum' temps.

Hmm, they've been mostly kept at 70-75F, but I've got it up to 85F at least and I'm trying to increase it.

I keep mine at 74 and they are taking forever to grow, as I expected. But I don't need them to breed fast since they are feeders for my 2 tarantulas.

I don't really need to breed mine quickly either, although it would be nice to have a backup food supply already. Mine are at that stage when they're almost too big to be fed to my frogs. I have about forty.

If they are adults you would know a male, they have very large obvious wings. To sex younger Dubias you can look on their underside, the females have 5 sections and the males have 6.

Elly you have done the right thing raising the temps. Tropical roaches will slow way down developmental wise breeding and feeding. With the temps in the sweet spot for breeding 80-90F you will see more action feeding and growth. Make sure humidity level is about 50% or greater even. You can lower the temps as needed to curtail reproduction in the future. Adult breeding males will be maybe 1 1/4 - 1 1/2 inches.

If you acquired roaches that are all the same age and lifecycle, they may become to big for your frogs all at the same time and suffer a long lag time before beginning to breed. You might consider purchasing a few breeding adults so that you have roaches in several life stages. When those adult breeders die or stop producing- your next generation will be breeding and there will be another generation of babies maturing behind them. This is why we sell Dubia Roach Starter Colonies that include all life stages (babies, Mediums and adult breeders. There will be a steady stream of babies to use as feeders with no one size predominating.
