I have seen similar behaviour in a few different species and the common denominator was a female ready to mate and males /females chasing each other all around trying to.....breed. Often too there will be a freshly molted female which I think they give off (in many species) a mating hormone that makes them all crazy. Watch Diploptera punctata when a female nymph molts into adult and all the males go nuts!I've often seen a similar behaviour in Schultesia lampyridiformis and Nauphoeta cinerea, and sometimes in Rhypharobia maderae "golden" too...But I don't know the reason...
I bet that would be very interesting to see !Watch Diploptera punctata when a female nymph molts into adult and all the males go nuts!
