This is a critter that has both positive and negative traits. On the plus side, leaf cutter bees are considered an important pollinator species for agricultural crops like alfalfa and clover. The negative is that they also chew circular notches on the edge of the leaves of certain ornamental landscape plants such as roses.

Leaf cutters are related to honeybees and have hairy bodies in black, metallic blue, green or purple colors.They do not eat the leaf material but, rather, they take it to line their nest holes. After the eggs are laid, they will use a leaf cut to plug up the cell to protect them.

Prune out dead and dying stems or damaged leaves. Remove dead twigs or plant debris from around the garden. Since these are pollinators and generally do little damage, chemical controls are usually not warranted.
