Please identify- mixed in with hissers

[Lorac]

Please identify these roaches that are mixed in with my Madagascar hissing cockroaches. I recently received this colony from a local children’s museum. I though some of the juveniles looked odd. The roaches in the photos have developed from those juveniles. What are they and how do I care for them? They have folded wings and are about 2.5 inches long. I am a high school science teacher and would like to separate and keep both types. Any help would be greatly appreciated. Thank you!

Appear to be Blaptica dubia, looks like an adult male and female.

To be 100% sure, I'd contact the Children's Museum and ask them what other roaches they keep in their collection.  You'll likely get an exact species, or at least narrow down the options.

Good Luck!

Looks like Blaptica dubia and those are commonly raised so it's probably just a few rogue dubia. Though Byrsotria fumigata looks very similar so you may want to ask the museum directly on an exact species match.
