They may also use plant resins or mud to create partitions within the tunnels, separating individual brood cells. These nests provide excellent protection against predators and adverse weather conditions.
Stem Nests
Stem-nesting solitary bees are skilled architects that utilize hollow plant stems as their nesting sites. They seek out suitable stems, such as those of pithy plants like sunflowers, reeds, or bamboo, and carefully excavate the inside to create brood cells. These bees have a preference for stems that are already hollow or have soft pith, making their task easier.
Once the stems are chosen, stem-nesting bees line the inside with leaves, mud, or glandular secretions, creating a cozy environment for their offspring. Each brood cell is meticulously provisioned with a mixture of pollen and nectar before an egg is laid. This ensures that the developing larvae will have ample sustenance until they emerge as adult bees.
Masonry Nests
Masonry-nesting solitary bees demonstrate remarkable adaptability by constructing nests using non-natural materials. These resourceful bees utilize crevices in masonry, such as walls, bricks, or even cracks in rocks, to create their nests. They skillfully manipulate these existing structures to suit their needs.
Masonry-nesting bees often use mud or chewed plant material mixed with saliva to build their nests. They may create multiple chambers within these crevices, each containing an egg and a food supply. The tightly packed mud or plant material provides insulation and protection against external threats.
In summary, solitary bees exhibit diverse nesting behaviors, each uniquely adapted to their preferred habitat. Ground nests, wood nests, stem nests, and masonry nests all serve as vital shelters for these remarkable pollinators.
