Q: In late September I noticed there were lots of large black bees hanging on my lantana. I thought they were dead. Nope! They are alive, but when I nudge them they barely move.

A: They’re sleeping! Bees of all kinds are well-known to rest on flowers, particularly near dusk or when it’s chilly. Some entomologists theorize that most of the resting bees are males who have no hive to return to.
