Osmia cornifrons is a cavity-nesting solitary species used as an apple pollinator in Korea. To elucidate the developmental characteristics of O. cornifrons, we investigated its development from the egg to adulthood, including a dormant prepupal phase and mating through indoor rearing (25 °C, 65% R.H.). The egg durations of the female and male bees were 3.6 ± 0.8 days and 3.1 ± 1.3 days, respectively. During larval development, the head widths of the 1st to 5th instars ranged from 0.7 ± 0.1 mm to 1.3 ± 0.1 mm. The peak of the growth in head width was the 2nd instar. The larval lengths ranged from 3.7 ± 0.6 mm to 13.6 ± 1.3 mm. The peak of growth was the 4th instar. The larval weights ranged from 4.5 ± 1.2 mg to 78.3 ± 16.1 mg. The peak of growth was the 3rd instars. The total larval durations of from the 1st to 5th instars for the females and males were 14.0 ± 6.0 days and 13.2 ± 5.8 days, respectively. The spinning durations of the females and males were 2.2 ± 0.7 days and 2.3 ± 0.8 days, the prepupation durations were 55.5 ± 5.9 days and 55.8 ± 2.9 days, and the pupation durations were 26.4 ± 2.1 days and 25.3 ± 2.3 days, respectively. The average longevity of the female adults and male adults was 21.8 ± 8.7 days and 24.4 ± 12.4 days, respectively. The total duration of from the egg to an adult bee of the O. cornifrons females and males was 123.5 days and 124.1 days, respectively. Mating consisted of the three following phases: the precopulatory (courtship and attempting copulation), copulation and postcopulatory phases. The mating times of the precopulatory, copulation and postcopulatory phases were 159.6 ± 288.9, 8.4 ± 7.1, 12.9 ± 4.5, and 198.8 ± 69.8 seconds.
