Red mason bees do not live in hives - they choose plant stems, slits in boards and even snail shells for their nests. The Polish name "bricklayer" comes from the specific skills of creating a nest, as the bee, after laying its eggs, uses clay or sand mixed with saliva to "brick up" the entrance to the nest.

Females live only for 7-8 weeks. After leaving the nest, they start breeding, and then start setting up a nest, collecting pollen and laying eggs (females die after the end of reproduction). The larvae hatch from the eggs laid in the nests and feed on the food collected by the female.

This insect starts flying in the first half of April and ends in June. This period coincides with the spring flowering time of most garden plants. The source of food for the mason bee is about 150 species of plants, both wild and cultivated.

Unfortunately, the bee population is declining. Therefore, it is worth ensuring that they have the best conditions for nesting (e.g. by placing special houses for insects) and sowing plants that will be a source of food for them.
