  1. Provide artificial nest sites for solitary bees

    Scott (1994) placed a total of 9,216 wooden nest boxes with small drilled holes of diameters 4.5-11 mm, on the edges of open fields in Upper Michigan USA, in April 1984 and 1985. Three species of the small solitary bee genus Hylaeus used the boxes, with an overall occupancy rate of 4%. These bees only used holes with the smallest diameters (4.5, 5.2 and 6.0 mm). H. ellipticus preferred the smallest 4.5 mm holes. Hylaeus basalis preferred nest boxes at lower heights 0.1 and 0.4 m above the ground and H. verticalis preferred higher boxes set at 1.1 m.
