Bees have a long proboscis, which they use to suck out the nectar of plants, as well as antennae (or antennae, ligaments), each of which consists of 13 segments in males and 12 segments in females. There are exceptions in males: 11 (or 12) segments in the antennae have some Systropha, 12 segments — some Euryglossina, Pasites, Biastes, etc.

In Australia, 58 genera and 1546 species of bees (half of which are from the family Colletidae) were known by 2018

They are found everywhere on all continents except Antarctica.

The size of bees ranges from 2.1 mm in the dwarf bee (Plebeia minima) to 39 mm in the Megachile pluto species found in Indonesia.

Many bee species are poorly studied.

All bees have two pairs of wings, the rear pair is smaller than the front; only a few species of the same s*x or caste have very short wings, which makes bee flight difficult or impossible.
