Mahogany Dun - Isonychia bicolor

These mayflies are quite particular as to which rivers they choose - even if the water is excellent quality, that doesn't guarantee that they will live there.

Habitat: Spotted under a light on a building in a rural area.

  Wow! I plan to go streaming in late winter/early spring, so maybe I'll find some naiads to add to the database! Posted 6 years ago

    Yes, please do try and find "Fresh-Water Nymphs of Greek Mythology". That's what I got when looking up "naiad". Posted 6 years ago

      Ha! Mayfly nymphs are also called naiads. They are fun to find in streams, along with dragonflies, etc. Posted 6 years ago
