Summer leafcutter bees are super pollinators of tomatoes, peppers, squash, melons, and peas - just about any flower. Gentle solitary bees who only fly about 300 feet daily as they forage for nectar and pollen. Easy to raise bees who prefer 6mm sized holes and use soft pliable leaves like those of rose, hosta, lilac, and pea to build their protective leafy cocoons.

You can reuse your spring mason bee house to raise summer leafcutter bees. Just place the summer leafcutter nesting tray into the house and add leafcutter cocoons! Or add the kit to your own bee house.
