Acrosticta is a genus of picture-winged flies in the family Ulidiidae, first described by Loew in 1868. The genus contains approximately 15 described species distributed across the Americas. Members of this genus have been documented as pollinators of orchids, specifically Acianthera aphthosa, where an unidentified Acrosticta species was the only successful pollinator observed.
