The multi-generational migration of the dragonfly

Between February and March, the first generation of dragonflies emerges from ponds and lakes in the southern United States, Mexico and the Caribbean. Then those resilient first-gen bugs travel hundreds of miles north as, making it to New England or the upper Midwest by May. When they get there, they’ll lay their eggs and die.

The lives of the next generation are just as incredible. While some of those second generation insects will hang out and overwinter in ponds and lakes in the north during their nymph stage, many will reach maturity and head south between July and October.

  1. Monarch butterflies have a similar (as referenced in the subheadline) multigenerational migration.

    I find it interesting to.imagine what a human multigenerational migration would look like. You'd presumably have legends and stories communicating the next steps along the path.

    It's a cool idea.
