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 ...
The bees nest underground in a variety of soil types, including beach sand, salt flats, dry river banks, clay, garden soil, and compacted dirt and shingle roads; nearly any soil type appears to be used so long as it is on relatively free of vegetation, has a relatively low level of moisture and a sunny aspect.
Colletes cuniculariusin nest entrance Colletes phaceliae Colletes compactus Colletes speculiferus Colletes thysanellae. The genus Colletes (plasterer bees or cellophane bees) is a large group of ground-nesting bees of the family Colletidae. They occur primarily in the Northern Hemisphere. They tend to be solitary, but sometimes nest close ...
Western honey bees show several nest-site preferences: the height above ground is usually between 1 metre (3.3 ft) and 5 metres (16 ft), entrance positions tend to face downward, equatorial-facing entrances are favored, and nest sites over 300 metres (980 ft) from the parent colony are preferred. [5] Most bees occupy nests for several years.
The northern colletes (Colletes floralis) is a species of bee within the genus Colletes.Northern colletes are solitary bees, though females may nest in what are termed aggregations – sites where the bees nest close together, but do not form colonies as social bees do. [1]
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.
The nests also have globular pot-like wax cell clusters. [5] In general, nests are constructed using wax mixed with resins, mud, feces, or other materials, otherwise known as batumen. Nests of the genus Trigona are built in cavities that can support these batumen plates created by the bees to shield and protect the colonies.
A cuckoo bee from the genus Nomada, sleeping (note the characteristic position anchored by the mandibles).. The term cuckoo bee is used for a variety of different bee lineages which have evolved the kleptoparasitic behaviour of laying their eggs in the nests of other bees, reminiscent of the behavior of cuckoo birds.
