satchellwk Posted October 12, 2012 Share Posted October 12, 2012 I found something rather odd today in my school's science lab. In a leftover beaker from a lab designed to separate particles from a mixture, there were three periplaneta nymphs at the bottom. Mind you, this is a small beaker, so it was obvious that they went in on purpose. The strange thing is that, as far as I knew there was nothing in there that roaches would be after. It contained sand, iron filings, Styrofoam, and salt. The most logical thing I can come up with is that they wanted the salt, but I had no idea they would flock to it like that. Has anyone else ever witnessed this behavior with other roaches? This also has me thinking, maybe our captive colonies would benefit from some extra salt every once in a while?

Keith Posted October 12, 2012 Share Posted October 12, 2012 Perhaps they tasted oils from our hands and accidently fell in? If someone touched any type of food then the beaker tats enough to draw them in. Quote Link to comment Share on other sites More sharing options...
Zephyr Posted October 12, 2012 Share Posted October 12, 2012 One may have gone in, found a comfy little semi-humid microclimate, and then attracted the others actively or passively with aggregation pheromones. Quote Link to comment Share on other sites More sharing options...
