Bog Hoverfly

The Bog Hoverfly (Eristalis cryptarum) is a species in the genus Eristalis. It is currently classified as Extinct on the IUCN Red List. Distributed across Belgium, Denmark, Norway, and Sweden.

A large, elegant wading bird reaching up to 1 meter in height, gray herons inhabit wetlands, rivers, lakes, and coastal areas across Europe, Asia, and Africa. Patient, solitary hunters, they stand motionless for long periods before striking fish, frogs, and small mammals with lightning-fast dagger bill strikes. They nest colonially in tall trees in rookeries called heronries, sometimes shared with other colonial waterbirds. Widely distributed and of Least Concern globally.
