Odd behavior in Nauphoeta cinerea

Recommended Posts

I have noticed a lot of behavior in my Lobsters(N. cinerea), and I can't tell what to make of it. I keep seeing a lot of them arch their backs and raise their wings vertically. They don't spread their wings, but just raise them upwards. Is this a territorial display towards the other roaches, or is it a mating display?

I'd really like to know what they are conveying towards each other. I never see my Discoids (B. discoidales) performing this act, so maybe it's a Lobster thing? Please enlighten me on this, and thanks ahead of time.

That is mating behavior. The males raise their wings during which time they emit a pheramone to entice the females to mate. The males may also become aggressive towards other males and chase them to establish dominance. BTW, most females mate within 6 days of the adult molt.
