Dragonflies in New Hampshire: identification guide and best places to start

1. Where are dragonflies most likely to be seen in New Hampshire?

Dragonflies thrive near shallow, still water. Top spots include the Great Bay Wildlife Refuge, Umbagog Lake, and the Lamprey River. You can also find them at small ponds, bogs, and seasonally flooded meadows. Backyards with a water garden or even a birdbath can attract a surprising number.

2. What time of year and weather conditions are best for dragonfly spotting?

The dragonfly season in New Hampshire runs roughly from late May to early October. Warm, sunny days with temperatures between 70-85°F are ideal. They are most active after a rain shower when humidity rises. On cool or overcast days, they often perch low on vegetation, making them harder to spot.

3. How can you identify dragonflies in New Hampshire?

Start with body shape: a long, slender abdomen and two pairs of wings that are clear or patterned. Note the wing venation and colors. Common species include the Common Green Darner (green thorax, blue abdomen), Eastern Pondhawk (green face, blue body in males), and Twelve-spotted Skimmer (six dark spots per wing). Look for their perching behavior: some species sit horizontally like darner, others cling vertically like spreadwing damselflies.

4. What are the most common dragonfly species in New Hampshire?

Besides the three mentioned above, keep an eye out for the Blue Dasher (small, pale blue with dark wing tips), Widow Skimmer (white-tipped wings), and the Halloween Pennant (orange patches on wings). Each has a distinct flight style: Blue Dashers dart low over water, while Halloween Pennants flutter like flags from perches.

5. What habitats attract the most dragonflies in New Hampshire?

Marshes, vernal pools, and the edges of slow-moving rivers are hotspots. Sandy-bottomed ponds with emergent vegetation are especially productive. In upland areas, dragonflies often gather near forest clearings and along hiking trails where sun filters through.
