The Mayfly - and the briefest of encounters
The eggs of mayflies are laid underwater, and the nymphs which hatch from the eggs can live for two years in the water.
Then come the summer, the adults hatch out - sometimes simultaneously and they can appear in their hundreds. Sadly, they have very short lifespan (just hours in some cases), during which they display and breed.
Many of them don't feed as adults as their sole purpose is to reproduce, dying once they have mated.
