Can I ask - what's Dubia?

And also - that's a relief because I don't think I could fit another vivarium in my room. I have two hides and the female has just eaten 3 mealworms. I haven't seen the male eat yet as he likes to hide away, but he's the bigger of the pair and they get on well. I often find them huddled up together quietly so I don't think there is a problem.

Cheers for the advice.
