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]

Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects.

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 9.6–1,315.3 mm (0.38–51.78 in) long, black with yellow bands, less prominent in the male. The larvae of this genus are known as rat tailed maggots for the long posterior breathing tube.
