Good hygiene makes us smell better and look prettier, but it’s also a health issue. Same goes for insects and cleaning up can make a big difference to their survival. It can keep their senses sharp and their aerodynamic bodies functioning at peak efficiency.
I’m not sure if I posted this one or similar from the same subject before, but I didn’t find anything in the BugPhoto archive looking similar. I’m also not too good with identifying bees, but I think this is from family Andrenidae, the mining bees.
