Summer leafcutter bees ship May through August. Select the Monday bee ship date that is the same week as when your summer blooms open.

Optional Leafcutter InvitaBee! Leafcutter bees tend to naturally disperse. Crown Bees has developed a pheromone that attracts more leafcutter bees to nest.

Sufficiently warm outdoor temps are important for success! Leafcutter bees need daytime temps in the 70's or warmer. Leafcutter bees are generalists and will pollinate a variety of flowers. Consider when your summer fruit and vegetable plants will actually flower. A seedling planted in May may not produce flowers until the end of June.

Please note: Leafcutter bees overwinter as larvae and require a period of warm weather to develop into fully formed adult bees. We incubate the larvae (a process that takes about 3 weeks) and ship them to you ready for placement in your bee house. If you select a ship date less than 3 weeks from your date of order, we will do our best to meet your requested ship date. Shipping of leafcutter bees will be on a first come - first served basis with priority being given to those who have pre-ordered their bees.

We cannot ship bees outside the United States. We apologize for any inconvenience.

Additional Information


We have incubated the summer Leafcutter Bees that we are shipping for you.  They will be ready to be placed directly into your bee house upon receipt.  

Instructions for Placement of Incubated Leafcutter Cocoons:

  • Upon arrival, refrigerate your bag of cocoons briefly for 15-30 minutes to quiet and still any bees that may have emerged in transit.
  • Remove the bag from the refrigerator. Standing in front of your bee house, open the mesh CocoonGuard Bag and place the open bag on top of, or behind your nesting holes, with open end of bag facing out or up and shaded from direct sunlight. If your bee house has an attic area, the open bag of cocoons can be placed in the attic space. Do not subject the cocoons to direct sunlight as that may weaken or kill your bees. As bees warm and development completes, they will emerge from their cocoons to fly, forage and frolic.
  • Small, perfectly round holes in non-fibrous leaves such as rose, lilac, bougainvillea or hosta are a sign that your leafcutter bees are busy and actively nesting.
  • Nesting bees should be active for a period of about 6 weeks. If you have placed out leafcutter cocoons in late spring or early summer, it is possible that you may experience a second wave of emergence.
  • In late summer/early fall (when leafcutter bee activity has ceased) remove the nesting tubes, reeds or trays from the bee house and store them in an unheated garage or shed.
