#MayflyMonday

Going through old #macroinvertebrate pictures and found this Heptageniid #mayfly collected last spring. Just look at those #gills in action! #freshwater #aquaticinsect

A lateral (side) view of a mayfly nymph. This mayfly, called Baetis bundyae from the family Baetidae, is from the group called "small minnow mayflies" due to their sort of round-ish, tubular shape. This specimen has large and well-developed wingpads, and long narrow gills along the side of the abdomen.

Image from the community of Rankin Inlet (Nunavut, Canada) showing a rock lined pathway between two bodies of water; on the left is Williamson Lake, and on the left is a small, shallow, grassy pond, where the mayfly, Baetis bundyae, was collected. The sky is blue, and there are Rankin Inlet buildings on the horizon.

A nearly mature specimen of Baetis bundyae, collected from a shallow grassy pond in mid-July 2003 in Rankin Inlet during a survey of streams around western Hudson Bay (Canada). It spends most of the year as an egg, hatching and completing development in a few short weeks in summer.

Let's get #MayflyMonday going! Here's a pretty little Epeorus from Yukon in northern Canada.

Mayfly gills are amazingly diverse. Often the fragile gills of Family Leptophlebiidae fall off in preserved specimens, but sometimes their relatively intact #mayflymonday #Ephemeroptera #macroinvertebrates
