What dragonfly species are most common in Maryland?
The most frequently seen dragonflies in Maryland include the **Blue Dasher** (Pachydiplax longipennis), **Common Green Darner** (Anax junius), **Eastern Pondhawk** (Erythemis simplicicollis), and **Widow Skimmer** (Libellula luctuosa). These species are widespread across the state and easy to spot near water bodies. The Blue Dasher, for instance, is a small, fast flyer with a bright blue abdomen in males, while the Common Green Darner is large with a green thorax and unmistakable when patrolling ponds.
How can you tell dragonflies apart from similar insects?
Dragonflies have stout bodies, two pairs of wings that are held horizontally at rest, and large compound eyes that cover most of the head. Look for wing venation patterns: dragonflies have wings with a distinct nodus (a notch on the leading edge) and a pterostigma (a colored cell near the tip). Their closest look-alikes are damselflies, which are slender, fold wings along the body when perched, and have separated eyes. Check out ourdragonfly animal hubfor more structural comparisons.
Where in Maryland are dragonflies easiest to spot?
Good bets include **Blackwater National Wildlife Refuge**, **Patuxent Research Refuge**, and the ponds along the **Chesapeake & Ohio Canal**. Dragonflies are concentrated near still or slow-moving water with emergent vegetation. Early morning or late afternoon after a warm day increases activity.

What time of year is best for dragonfly watching in Maryland?
Peak dragonfly season runs from **late May through mid-August**, when most species are active. The earliest emergers, like the Common Green Darner, appear in April, while late-season species such as the Autumn Meadowhawk (Sympetrum vicinum) persist into October. For best odds, aim for warm, sunny days with light wind during late spring and summer.
Which Maryland dragonflies are most distinctive?
The **Great Blue Skimmer** (Libellula vibrans) is large with a pale blue body and white face, often seen on lily pads. The **Halloween Pennant** (Celithemis eponina) has orange-brown wings with dark bands, resembling a fluttering flag. The **Twelve-spotted Skimmer** (Libellula pulchella) has twelve dark wing spots and a powdery blue abdomen. Use wing markings and body color as primary field marks.
How do you separate dragonflies from damselflies?
Damselflies are generally smaller, with thread-like bodies and eyes separated by a gap. When resting, damselflies fold their wings vertically against the body, while dragonflies hold them flat out. Dragonflies are stronger fliers and often patrol larger territories. For example, a familiar bluet (damselfly) is slender and sits with wings closed, whereas a pondhawk (dragonfly) perches with open wings.
What are some ways to enjoy dragonflies beyond spotting?

Are there rare or unusual dragonfly species in Maryland?
Yes, the **Ebony Jewelwing** (Calopteryx maculata) is a striking black-bodied damselfly with metallic green wings, found along wooded streams. The **Lancet Clubtail** (Gomphus exilis) is a small, green-eyed dragonfly that prefers clean rivers. These are less common but have dedicated followers. Always check the Maryland Department of Natural Resources for updated species lists and conservation status.
What is the largest dragonfly in Maryland?
The **Common Green Darner** (Anax junius) is among the largest, reaching about 7.6 cm (3 inches) in length. The **Swamp Darner** (Epiaeschna heros) is similar-sized but has a brown thorax with green stripes. Both are strong migrants and may turn up anywhere in the state.
