Help with nymphs please!

Recommended Posts

I accidentally dumped some adult dubia roaches into my colony of adult hissers and now one of them has been breeding. I want to seperate them but I'm not sure which specied (god forbid both) had the nymphs. Is there an easy way to tell the two apart. The nymphs can't be more than a few days old but they are a centimeter long. and greyish. If someone with both species could show me some pictures of each that would be SUPER helpful. I need to get these guys apart before it becomes a lost cause!

Thanks!!

Hisser's nymphs are brown-black, but are not burrowers

I used to have hisser nymphs and they burrowed under the substrate, most roach nymphs do except mabye pest species.

I believe that dubia nymphs play dead when you pick them up and turn them over. ^^

You may also notice that hisser nymphs are (usually) elongate and dubia nymphs are more ovoid. Also, hisser nymphs have markings near the "shoulder" area and dubia nymphs are relatively uniformly mottled/colored.

I found Hisser nymphs have white tips on the end of their antennae, but your right they can look very similar.
