Two kleptoparasitic scorpionflies, Panorpa rufescens Rambur (Mecoptera: Panorpidae), were observed stealing food from Araneus bicentenarius (McCook) (Araneae: Araneidae) at Waterboro Barrens Preserve, York County, Maine. The spider's ensnared prey was a larva of Lapara sp. (Lepidoptera: Sphingidae), which provided food for both spider and kleptoparasites. This is the first recorded instance of kleptoparasitism by scorpionflies on an orb-weaving spider in Maine.
