Functional morphology of pollen capture in Syrphid flies (Diptera syrphidae): The effects of pile density and body region

Abstract

This paper will focus on Syrphidae, an understudied but potentially impactful pollinator. Specifically, I will investigate how the density of the pile (hair) affects the amount of pollen grains carried. This research has the potential to significantly contribute to the field of entomology, as it addresses the controversy about the efficiency of Syriphidae as pollinators, especially in the context of the global decline of primary pollinators such as bees. To conduct this, I will gather Syrphids using the established protocol from the Berry Brosi Lab. The Syrphids will be microscopically examined to determine their pile density and the number of pollen grains present. I expect that as the pili are more dense, more pollen grains will be gathered by a Syrphid fly. Additionally, I will be examining six body parts and comparing the differences in the amount of pollen grains they can carry. I expect essential body parts for pollination, such as the face and ventral thorax, will contain more pollen grains than passive body parts. This research is significant due to the lack of comprehensive studies on Syriphidae, particularly regarding their roles as pollinators.
