Leafcutter Bees Profile
Leafcutter bees (genus Megachile) are fascinating and often misunderstood creatures. They belong to the family Megachilidae, which includes over 1400 species worldwide.
Some gardeners see them as pests because they can damage the leaves of plants, like roses or shrubs, by cutting half-moon shapes out of them. Unlike other pests, such as caterpillars or grasshoppers, leafcutter bees don’t eat the foliage. Instead, they use the leaf pieces to create nest cells.
The cut-out leaf becomes a nursery chamber where the female bee lays an egg. She also adds nectar and pollen to each chamber. These nest cells look a bit like the end of a cigar.
