- The subimago (a winged, but usually sexually immature stage) in the life cycle of mayflies is unique among living insect orders. The Ephemeroptera have two winged-instars, the subimago and the adult (or imago).
- 2009, James H. Thorp, Ecology and Classification of North American Freshwater Invertebrates:
- Subimagos emerge at the surface, fly to a support, molt immediately to the adult stage, live only a few hours, swarm, and mate shortly after ecdysis.
- 2011, Rüdiger Wagner, Central European Stream Ecosystems: The Long Term Study of the Breitenbach:
- Subimagines flutter away immediately and rest at protected sites near the stream for up to 2-3 days, until the molt to the very short-lived adult occurs.
