Need ID please

[Huntsman]

These lads were found in the NW part of South Africa.

Can anyone assist with an ID, please?

Cheers!

looks like N. Rhombifolia (Harlequin roach). Pattern looks right to me, but the black is a little more pronounced than the colony I used to have.

Are you sure those are adults?

Hi Orin -

No idea. This question was posed on a local site, but no-one could answer it, and I thought I'd try to help...

I thought they looked like N. rhombifolia too, but they were found wild and I don't believe we have that species here, but...who knows? :mellow:

 

[RosenKrieger]

They are in some parts of the US. Where did you find them?

That species is cicumtropical and that coloration looks like some I've seen. They appear to be older nymphs so it's hard to say. It's certainly a way better guess than the bugguide people telling one of our members his Parcoblatta is B. orientalis.

If I had to take a stab at it I'd say they're either N. rhombifolia or some Periplaneta or related genera nymphs.

Thanks, chaps!

Kyle, compare the pattern on the pronotum and also, you can compare the 4 dots on the plates over the thorax. That's what makes me think its a Harlequin. That picture I posted is one I took of my harlequins when I still had them.
