## Summary

Eristalinus aeneus (Scopoli, 1763), the common lagoon fly, is a fairly common species of syrphid fly observed throughout the United States and Europe. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae occurs along shorelines in rock pools containing large amounts of decaying seaweed.
