Are you sure? Grasshoppers lay eggs that can drown! Hatchlings are at best a
pronymph, that being a nymph wrapped in a larval cuticle that is very
quickly shed post-hatching. There are then a few progressive nymphal stages
until adulthood. At this stage they swarm. If the story is true, I'd very
much like to see more of it (which I will attempt to do). I'm an
entomologist by training, and have never heard of such a life cycle for
locusts. They weren't dragonflies were they?
