...rom March to June. They are often visible on deadnettle (Lamium) or on other species of the mint family (Lamiaceae), as well as on borage (Borago officinalis) and species of the primrose family (Primulaceae).
The females dig tunnels in loose soil for their nests. These tunnels are approximately 100 mm long and sometimes branched. It can happen that several females build their nests very close to each other. The nests are equipped with small chambersshaped like hazelnuts, which are smooth...
...tar. The hatched larvae feed on the puree until early autumn, thereafter they pupate within the brood chamber. They overwinter as pupae and hatch as adult bees in March. Among the parasites who feed on the brood of Anthophora and Amegilla is the oil beetle Sitaris muralis. In march, the female Sitaris muralis beetles place an egg on the fur of hatched male Anthophora and Amegilla.
During mating the eggs are transferred to the fur of the female bees and are thus transported unnoticed into ...

During mating the eggs are transferred to the fur of the female bees and are thus transported unnoticed into the bees’ nests. The hatched larvae of the oil beetle feed on the food stores and on the brood of the Anthophora and Amegilla bees.

Food plants are chosen particularly because of their ethereal oil (mustard oil) content, which the females detect using chemosensors, which are on their forelegs. In order to avoid egg laying on the same plant by other orange tips, the female leaves odoriferous substances (pheromones) on the leaves.

| | | Beeswax | | Beeswax (Cera Flava) is a product of bees’ wax glands. It is used to build honeycombs. The wax is initially white, but becomes progressively more yellow as a result of contact with pollen oil (from flower pollen). and comes after previous treatment again as a white wax in the trade.
The wax can be treated to return it to its original colour. In industry most of the wax now used is artificial or synthetic. The largest consumers of be... | | |
