Acrosticta
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.
Cerataphis orchidearum
Fringed Orchid Aphid
Cerataphis orchidearum is an aphid species in the family Aphididae, commonly known as the fringed orchid aphid. It has been recorded on orchid hosts (Orchidaceae) and on Daemonorops lewisiana, a rattan palm. The species has been observed in association with yellow crazy ants (Anoplolepis gracilipes), which tend the aphids. Its distribution spans multiple continents, including Europe, Asia, Africa, the Americas, and Oceania.
Cryptorhynchina
hidden-snout weevils
Cryptorhynchina is a subtribe of weevils within the subfamily Cryptorhynchinae, commonly known as hidden-snout weevils. The group has gained scientific attention through fossil evidence showing that at least one extinct species within this lineage served as an orchid pollinator approximately 20–45 million years ago. No present-day members of this subtribe have been documented carrying orchid pollinaria, though this absence may reflect their secretive behavior rather than lack of ecological interaction.
