They are sometimes called the hummingbird moth. The caterpillar is up to three inches long and is mostly green, but may vary from pale green to black, usually with some black stripes or patches on the back. They feed on a variety of plants, including beets, fuchsia, grapes, melons, elms, apples, peaches, etc. Despite their large size, they are not a very destructive pest. However they do tend to migrate into urban areas, and end up in pools or homes.
Bees are robust, hairy insects.
They feed on nectar and pollen from flowers, and their hind legs are flattened into a surface for carrying pollen. Wasps are more slender than bees and have a severe constriction between the thorax and abdomen. They are often brightly colored, with contrasting black and yellow patterns. Their legs are narrow and cylindrical. Wasps are parasites or predators, and feed on other insects and spiders.
