A Leafcutter Bee (Megachile species) visits the blossoms of a Wild Bergamot (Monarda fistulosa), a native wildflower also known as Bee Balm or Horsemint. Like Mason Bees (Osmia species), leafcutters will readily nest in the tubular cavities provided inside man-made bee houses. As their names suggest, Mason Bees use mud to construct and seal the cells for their eggs while leafcutters harvest leaves for the task. Female Leafcutter Bees, including this individual, can be recognized by the accumulation of pollen carried on the underside of their abdomen. Within each nest cell, a female will lay an egg atop a supply of pollen and nectar. These provisions will nourish the larva through development and transformation into an adult.
