I suppose that having been a feral swarm that moved in, they already have established, favorite nectar sources. I am willing to bet, however, that when my neighbor's red crepe myrtle trees bloom, they will stick around more. There are some dwarf crepe myrtles at our county middle school, and honey bees were tearing them up last summer. But surely they will visit my vegetables soon. Last year, i didn't see a single honey bee in my yard. I know, because I purposely watched every time I went out. Carpenter bees, wasps, and jackets, but no bees.
