I get its supposed to be a sort of camouflage, but the group that had the best results also happened to be the only one that had stripes and a full cover of paint.
The one concern I have with the other types of tests is that I’m not sure flies are attracted to non-animal surfaces in the same way. But then again I don’t know the mechanism of how a fly targets where to go and then how it gets there navigationally.
