  1. Provide artificial nest sites for solitary bees

    Three species of wild megachilid bee (Megachile spp.) nested in boxes made from blocks of pine wood drilled with 14 mm long, 8 mm diameter holes, in a small replicated trial in Arizona USA (Armbrust 2004). Three sites were in the Tucson Mountains, one site on undeveloped land within Tucson city. Four nest boxes, each with 33 holes, were placed at each site. Overall 34% of available nest holes were filled between May and July 2001, but only six nests (4.5% of the available holes) were constructed in boxes at the urban site.

  2. Provide artificial nest sites for solitary bees

    Armbrust (2004) placed four nest boxes made from blocks of pine wood drilled with 14 mm long, 8 mm diameter holes at each of four sites in or near Tucson, Arizona, USA for one summer. Overall, 34% of nest holes were filled, by three species of Megachilidae. Of the filled nests examined, 27% were subsequently occupied by parasites or predators.
