Mayfly Nymph (Order Ephemeroptera) - Siphlonurus sp.

Nymphs have lateral, plate-like gills on their abdomen. There were TONS of these nymphs in the water today.

Habitat: Woodland pond; I used an aquatic net to scoop this nymph out of the water and took the photo in a sampling tray.

  Oh, and it's soooo cool to watch them swim around. They "flutter" their gills in such a neat way. Posted 4 years ago

    This whole video is pretty awesome, but it shows a mayfly larva in the beginning:
