Moths seems more attracted to lights with UV (Mercury Vapor), why is that? UV is something that is normally only present during the day. What about bees? Are they more UV sensitive?
I have a hive set up next to a plant propagator. I have some lights inside the propagator set on a timer to produce an extended photoperiod to trick the cuttings into breaking bud. This is within 4 feet of the hive. The bees can see the light and SOME come out and fly around. Not many though. If you’ve got a lot of bees flying at night, you have a problem because those bees will never make it back to the hive alive.
As Brian says, bees are attracted to light. I would also be cautious walking around the hive with a flash light at night. They will fly toward the light.
