That means people are seeing dragonflies in huge numbers up and down Lake Michigan. DuBois says weather and migration patterns are both playing a role.

Heavy rains helped bring many insects, including mosquitoes. Dragonflies eat those insects , which also contributes to their growing numbers.

Also, wind patterns seem to have forced more of the dragonflies onto the shoreline than usual.
