Got some Dubia roaches to start off my own colony. As I was sorting them to see how many females I got I noticed this guy:

I haven't kept these before bit to me this looks like juvenile male, so that weird translucent thing is propably not eggs 😅 He's also the smallest of the bunch and has one antenna always kinda curled.

Anyone know what's going on with him? Should I be worried?

I’ve only seen this happen to a female , I can’t say what it actually is if your roach is male.

I suspect that's a female not a male only females can do that. And as far as I know they will look identical till the ultimate moult of the males where they get wings so before that moult you can't tell gender but looking at the size of the roach on your hand gunna say young female not male.

One of the guides I found for sexing dubia nymphs. The last abdominal scale on the male nymph is smaller and the "line" between scales is close to the cerci. In the female nymph the scale is large and the cerci are in middle of it, far from the line. According to this I'd say my roach is male. Is this info I've found not correct?

But even if the roach is indeed female, it's still a nymph. So wouldn't it still be weird for a roach not yet sexually mature to have an eggsack? Or could it be some other part of their reproductive anatomy? Also it seems to be out constantly and not just sometimes like how when females "air out" their eggs. Could they have gotten hurt when the pet store worker caught them for me?

If He/She Is Laying eggs ... He/She is most likely Female. ;)

I used eggs in quotation marks because it was the shortest description I could think for what it looks like to put in the title. The roach hasn't laid anything and is just constantly looking like that. Also nevermind the sex, it's still a nymph.
