Abstract

We report for the first time the syrphid fly, Syritta flaviventris (Macquart), collected in Lancaster County, Pennsylvania, as the northern-most record for this introduced Mediterranean species. In total, 3 male specimens and 1 female specimen were net collected on three flower species (Verbena hastata, Eryngium yuccifolium and Asclepias incarnata), at a single site of 11 monitored farm sites in southern Pennsylvania. Floral records for the similar introduced sibling species, Syritta pipiens (L.), are presented as well. Passive monitoring with colored pan traps used to monitor bee populations at these sites was not effective in collecting either species of Syritta. Our study suggests that increased active net sampling of Syritta species may provide more information about this genus' distribution in the New World and support future research efforts examining Syritta biology and life history.
