Why do bugs swarm over water? - Luke M. Jacobus

Trace the life cycle of mayflies, and explore why these swarming insects are a sign of healthy aquatic ecosystems.

--

For most of the world’s 4,000 mayfly species, adulthood lasts roughly one day. And for some species, it’s only a matter of minutes. This isn’t because they’re all eaten up by predators. Rather, this abridged adulthood is a natural part of their life cycle. So, what role do these bugs play in their ecosystems? Luke M. Jacobus explores the stunningly short life span of the winged insects.
