Colletidae is a small family of bees. They use a material similar to cellophane to build their nests and thus they are called cellophane or plasterer bees.

Carpenter bees belong to the Apidae family.

Xylocopa. The most familiar ones are the large carpenter bees of the genus Xylocopa. They get their name from their habit to drill holes in wood for nesting purposes. They prefer soft and untreated wood.

Ceratina. There are also small carpenter bees, Ceratina. They look very different and are considerably smaller. Instead of making their own nests by chewing on wood, they choose hollow twigs for nesting.

All the bees in the subfamily Nomadinae of the Apidae family are cleptoparasites, meaning that they lay their eggs in the nests of other bees and their larvae feed on the stored food as well as on the egg or larva of the host species. They don’t gather pollen, however they visit flowers in search of nectar and of hosts, so they accomplish some pollination. Many of them are active early in the spring and quite a few parasitize Andrenidae, another group of early bees. They are a difficult group, only a few can be identified to species by photos alone.
