Xylota quadrimaculata , (Loew, 1866), the Four-spotted Leafwalker , is a common species of syrphid fly observed in central and eastern North America. Syrphid flies are also known as Hover Flies or Flower Flies because the adults are frequently found hovering around flowers from which they feed on nectar and pollen. Adults are 8.2–11.3 mm (0.32–0.44 in) long, black with yellow-orange spots on the abdomen. The larvae of this genus live under bark in sap runs.[3]
