Why Do Leafcutter Bees Cut Leaves?
Leafcutter bees are a type of bee, but they are different from the common honey-collecting bees we see. They have a cluster of golden short hair on their abdomen, and they do not use it to make honey. They are named after their habit of cutting semicircular pieces from the leaves of plants and bringing them into the hive.
The purpose of leafcutter bees cutting leaves is to build houses and breed the next generation. Leafcutter bees are solitary insects, so they usually do not appear in groups. Remembering this point can help in preventing leafcutter bees.
After mating, leafcutter bees start looking for abandoned holes of other insects or gaps in things as places to breed their offspring. Leafcutter bees roll the cut leaves (especially leaves of Rosaceae plants) into tubes and seal one end to form a nest chamber. Then, they start collecting pollen and nectar, mix them into bee bread, store it in the nest chamber, lay one egg, and then seal the top of the nest chamber with a circular leaf. The second nest chamber is built directly on top of the first, until the nest or tube is full of chambers. Once the nest is full of chambers, the entrance is sealed with resin, wood, or soil.
The lifespan of adult leafcutter bees is about 60 days, during which they can build 35-40 nest chambers and lay 35-40 eggs.
