Bumble or Not

These , I think, are two bumble bees in my garden.

This I think, is a carpenter bee, which has a larger head and short hairs, or no hair on the abdomen.

A honey bee

A black swallowtail buttefly in my garden. Was she there to lay eggs on the bronze fennel? Since I will be going on vacation on Sunday I did not check for eggs, but I will be looking for caterpillars upon my return.
