Natural History

Behavior

The Black Saddlebags is fairly migratory in Minnesota, with adults coming from the south in early summer and their offspring emerging in late summer and heading south. They can often be seen hawking with darners, gliders and other saddlebags especially in the late summer.

Habitat

Marshy lakes, ponds and slow moving streams with a lot of aquatic vegetation. Sometimes also temporary pools.

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 se flies back up the male grabs here in tandem again, ensuring that she can not mate with another male. Rarely females will oviposit on their own
