Pseudopolycentropodidae

Pseudopolycentropodidae is an extinct family of scorpionflies known from the Mesozoic. Fossils are known from the Middle Triassic (Anisian) to the early Late Cretaceous (Cenomanian). It is part of Mesopsychoidea, a group of scorpionflies with siphonate proboscis. They are suggested to have been nectarivores, feeding off the liquid pollination drops and acting as pollinators for now extinct insect pollinated gymnosperms such as Bennettitales.^[1][2]
