Robins are back

Yesterday was a fine warm day where the temperature got above 10 degrees. The snow is rapidly melting and the robins have finally returned. The day before yesterday I saw my first robin on the berm.

This is an exciting time of year when each day one or two new insect species make their first appearance after the long winter. Yesterday the flies like the one below were out in force.

Cluster Fly (Genus Pollenia)

Cluster flies overwinter as adults and are the most common fly around in early spring according to one commenter in the bugguide. Their larvae are parasites of earth worms.
