Brown banded roach light sensitivity?

[pannaking22]

Out of curiosity, how do brown banded roaches react to light? There are tons in the insectary on campus and they could care less that the lights are on in the building or that there are people moving around. Is that normal or have they developed some sort of weird tolerance to this?

Interesting. In the few times I encountered them in the field, I noticed a few things. In a 16 floor building they only inhabited the units where the tenant kept the temps above 78. They were mainly in the top floors where the units stayed hotter. Also they only were found in the top shelves of the highest cabinets. It was also the only place you would find the oothecas glued.

There are a ton of them in some of the buildings on campus. They don't love light, but they tolerate it. You see more when the lights are off, but you still see them when the lights are on.

Depending on the room, it seems like they come out more when the lights are off, but most rooms on all floors have them wandering around during the day with lights on and people around. Very strange. I wonder if they're just so used to it that they don't care anymore or if there's some sort of behavior evolution going on. Might have to try testing that out....
