Natural History

Behavior

Once a rare site in Minnesota the Red Saddlebags range has seemed to expand northward. They are now frequently seen across the southeastern corner of the state and there are even records of the species up on the Arrowhead. They are strong flyers that typically migrate into Minnesota from the south during the summer. They can often be found feeding in mixed swarms of darners, gliders and saddlebags

Habitat

Permanent or temporary lakes, ponds and slow-moving streams, preferably with little mud and no fish

Reproduction

Typically lay eggs while flying in tandem. Pair fly low above the water. Then the male releases the female who flies down to the water and dips her abdomen once releasing the eggs and as she flies back up the male grabs here in tandem again, ensuring that she cannot mate with another male.
