Solitary bees, such as Osmia cornifrons, O. pedicornis, O. satoi, and O. taurus (Hymenoptera: Megachilidae), have the potential for cost-effective and sustainable pollination, necessitating a comprehensive understanding of their ecological traits to implement effective fertilization strategies for various crops. This study investigated the nesting rate of Osmia spp. in different regions and altitudes, using various trap types, and found that the highest nesting rate occurred at altitudes of 300–399 m a.s.l. and showing a preference for bamboo-type traps, with the Andong region having the highest nesting rate overall, indicating the influence of altitude, habitat area, and trap type on the density of Osmia spp. nests. The distribution and diversity of the four Osmia spp. in different regions and altitudes revealed variations in their occurrence, with O. pedicornis having the broadest distribution rate, particularly at altitudes above 300 m a.s.l.. The present study found significant differences between species in the cocoon masses of O. cornifrons, O. pedicornis, and O. taurus, with region and altitude influencing the masses of each species too.
