Ebony Jewelwing

Usually we think of damselflies as being smaller and more delicate than the large robust dragonflies. But at two inches in length, the spectacular ebony jewelwing is an exception as it is larger than many dragonflies.

There is a similar species called the river jewelwing, but their wings are more slender and the first two thirds of the wing are smoky transparent with only the tips being coal black.

These damselflies are among our most beautiful insects. Their brilliant metallic green bodies flash sunlight as they flit around streamside vegetation and their large black wings quickly attract attention.

They are also short-lived, usually only living as a flying adult for about two weeks.

Watch for Behavior

These insects have the unnerving habit of turning their heads and watching their human observers, as the male is doing above. It is one of these insects fascinating qualities that has made it a favorite of many.

Also watch for courting behavior. A perched female, when courted by a male, will accept his presence by rapidly opening and closing her wings. If she rejects him, however, she will open her wings and leave them extended.

Did You Know?
A canoe trip in the Mississippi River Gorge between Minneapolis and St. Paul, MN feels like you are miles away from civilization even though you are in the center of a large metropolitan area.
