Hesperapis is a genus of evening bees in the family Melittidae. There are at least 30 described species in Hesperapis.[1][2][3][4][5][6]
Behavior

One species, Hesperapis rhodocerata, was recorded in one area in 2010 and 2015, appearing in those years but not the years in between. This suggests that their diapause may be prolonged over multiple years.[7]
