Cage for experiments about color vision of insects

Inspired by Cornell Institute for Biology Teachers: Crickets’ Response to Light (https://cpb-us-e1.wpmucdn.com/blogs.cornell.edu/dist/3/1009/files/2015/05/Crickets-Light-CIBT.pdf) we designed a cage, which is better than the original one.
Our full thesis (german only) is available on demand, the chapter about color vision is under downloads.
