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 ...
Bees are winged insects closely related to wasps and ants, known for their roles in pollination and, in the case of the best-known bee species, the western honey bee, for producing honey. Bees are a monophyletic lineage within the superfamily Apoidea. They are currently considered a clade, called Anthophila. [1]
Families would have one or many log-hives hanging in and around their houses. Although they are stingless, the bees do bite and can leave welts similar to a mosquito bite. The traditional way to gather bees, still favored among the locals, is find a wild hive, then the branch is cut around the hive to create a portable log, enclosing the colony.
The hollow can reach 30 cm (12 in) long by 1.1-1.4 cm diameter. Larger pieces of wood may allow for multiple tunnels. Several female bees may use a nest, one breeding and the others guarding. A bee defends the 0.7-1.0 cm wide entrance by blocking it with its abdomen (compare Allodapula). Both male and female bees may overwinter within the tunnels.
In T. carbonaria colonies, only some of the bees do the foraging. Workers spread out in all directions surrounding the colony, and quickly locate the best option nearest the nest. Once this area is found, they mark the food sources with a pheromone. Marking is used as a guide to make the location easier to find for their nest mates. [20]
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus Bombus, part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., Calyptapis) are known from fossils.

Andrena is a genus of bees in the family Andrenidae.With over 1,500 species, it is one of the largest genera of animals. [2] It is a strongly monophyletic group that is difficult to split into more manageable divisions; [3] [4] currently, Andrena is organized into 104 subgenera. [2]
