HOSTS: Rose family plants, ash trees and a wide variety of plants.

DESCRIPTION: Adult leafcutter bees resemble dark, robust honeybees.

LIFE CYCLE: Leafcutter bees are solitary bees. The female cuts leaf disks to create individual thimble shaped rearing cells packed with pollen.

CONTROLS: There is no legal control of the bees since they are important pollinators and thus protected. However, hot pepper wax reduced feeding in one grasshopper study and may help to repel leafcutter bees if sprayed several times during their active period.
