Andrena scotica is one of the earlier bees to appear and the flight period is mid March to late June with numbers peaking late April and May. The females are facultative communal nesters with a group of them sharing a common entrance to a burrow in which each female tends her own eggs and larvae within a chamber off the main burrow, constructing brood cells within her tunnel and provisioning ...
Like many other solitary bees, they can often be found nesting in dense aggregations, [4] sometimes numbering many tens of thousands of nests. In parts of the west European range of the species, Colletes hederae are frequently parasitized by the larvae of the meloid beetle Stenoria analis , [ 2 ] which feed on the supply of nectar and pollen ...
It is capable of surviving in old bee nests and infesting new hosts that reuse these nests or the nest material. When mites are trapped in the innermost cells of an infested nest or all bee larvae are killed and therefore cannot transfer mites to a new nest as adults, inert deutonymphs can be very important for mite survival.

The substance is rich and high in protein. These protein-rich secretions are then stored in pot-like containers within the nest until it is time to feed the immature bees. [5] The secretions replace the role of both pollen in the bees' diet, as vulture bees lack adaptations for carrying pollen and pollen stores are absent from their nests.
While some colonies live in hives provided by humans, so-called "wild" colonies (although all honey bees remain wild, even when cultivated and managed by humans) typically prefer a nest site that is clean, dry, protected from the weather, about 20 litres (4.4 imp gal; 5.3 US gal) in volume with a 4–6 cm 2 (0.62–0.93 sq in) entrance about 3 ...
A C. pallida female will find a spot for her nest. She will then dig diagonally down about 12 inches (30 cm). At the end of this tunnel, she will dig a 1 inch (2.5 cm) long vertical chamber where the egg will be laid. The chamber will be about 8 inches (20 cm) below the surface. In this chamber, the female will form a brood pot lined with wax.
Each egg is laid in a different nest of a bird of another species, including some woodpeckers, barbets, kingfishers, bee-eaters, wood hoopoes, starlings, and large swallows. It is common for the female greater honeyguide to break the host's eggs when laying her own. [16] All the species parasitized nest in holes, covered nests, or deep cup nests.
Arboreal nest in Guatemala. Trigona is one of the largest genera of stingless bees, comprising about 32 species, [1] exclusively occurring in the New World, and formerly including many more subgenera than the present assemblage; many of these former subgenera have been elevated to generic status.
