Mason Bee & Leafcutter Bee nesting reeds in various quantities. Reeds approx 1/4 inch to 5/16 inch in diameter, 6 inches long. Use for Mason Bees, Osmia Texana, Osmia Californica and Leafcutter Bees. No two bees are the same size – with reeds you get a variety of hole sizes to offer the female bee. These are all natural reeds and variability from one reed to the next is to be expected
