Perdita are tiny sand sprites. Bees in this genus are affectionately known as “fairy bees” and they are most diverse in the desert southwest, with only a handful of species found in the northeast. Because of their tiny size, tight association with sand, and often strict host plant requirements, Perdita are rarely stumbled upon. In the right place at the right time, however, they can be locally abundant.

In addition to their miniscule size, Perdita have rather flattened abdomens and are often adorned with distinctive patterns of pale markings. Look out for females carrying round, nectar-moistened pellets in their scopae – most other small bees in our area (like Lasioglossum and Ceratina) carry pollen dry.
