You’ll probably only see one type of dragonfly this late in the season, the autumn meadowhawk is unique in that way. These dragonflies start as naiads in spring, hatching from eggs laid in the water.

Autumn meadowhawks sunbathe on warm, sunny days to collect heat that helps get them through colder fall days. Due to how late these dragonflies are active, they make a perfect snack for birds as they migrate south for the winter. ![]()

They enjoy wooded areas, spending much of their time away from the water until it's time to lay their eggs. Autumn meadowhawks aren’t territorial like other dragonflies, which often leads to multiple pairs laying their eggs at the same site.![]()

The autumn meadowhawk has yellowish-brown legs, unlike most meadowhawks that have black legs. They used to be known as the yellow-legged meadowhawk until its name was changed in 2004. This change was made because the legs on mature adults appear more brown, causing confusion for many people trying to identify the species. ![]()
