I noticed I have honeybees mostly in my garden but lately there is a smaller bee (which has the honey bee coloring) with long antenna. They are very quick in their movements from flower to flower. They also fly on top of other bees of their species trying to get them off that flower. What type of bee is this?
Could be a leaf cutter bee.
Could be a leaf cutter bee. Do the leafs on the plants in your garden show any leaf cutter bee damage. You can Google leaf cutter bee damage to get an idea of what it looks like.
