Chalk-fronted Corporal, male (Ladona julia) — With a pair of chalky-white bars on the top of the thorax, you can see where this dragonfly got its name. They can be found across the northern U.S. and Canada. These dragonflies are highly gregarious and can be seen basking in groups. Photo by Glenn Marangelo on 7/11/17 near Seeley Lake, MT.
