Last night, one of my adult female Polyphaga saussurei roaches surprised me with her effort to climb the temperature sensor hanging in the enclosure. As I mentioned previously, my adult saussurei roaches are, let's say... restless. It's the same every evening, a few hours after the lights go out (except the red lights). What I had not expected, was how 'motivated' this roach was to climb to a higher spot. My hypothesis at the moment is that these roaches try to find a higher spot (be it a trunk or a rock) to sit on and be found by a male. I'm pretty sure there is more than meets the eye: pheromones most likely (love is in the air?). The sub-adults stay hidden all the time, but this one... I could even touch her and it took some probing for her to release and burrow again in the substrate (to reappear half an hour later). I changed the wire configuration to thwart the next attempt (the enclosure does not have a lid, as I did not expect such action from these 'non-climbers'). Anyone else got such bold Polyphaga roaches?
