Distinct Creobroter Marking

[agent A]

Hello all, recently I got subadult male and yesterday some L4 nymphs of a creobroter species that some say is pictipennis and others are a bit confused on the ID of

im certain all 12 of mine are all the same species because of a distinct black marking underneath the thorax, i didnt see this in gemmatus so im wondering if it is a species indicator, and im also wondering if anyone else has seen this before

can someone please help clear this up? thanx

The species indicator regarding Creo is the pronotum(all green for pictipennis and the back of the head(as far as I know)and you are also right about that black marking.But a they are many other dictinct indicators an entomologist could notice.

But it is always easier to identify a species once it is adult.

i have a pic of the front of the thorax:

My C. gemmatus never looked like that. I'd say its a C. pictipennis.

Looks pretty much identical to the L3 (I think... maybe 4?) C. pictipennis that is crawling around on me right now Can't see her underside in this picture but she has the exact marking you picture above.

Is there a way to tell one instar from another?

I took the picture by putting it in a plastic cup so as he was on a wall of the cup I had a good view of the marking
