Dragonflies Sounds in Arizona: A Field Guide to Listening

1. What sounds do dragonflies make in Arizona?

Dragonflies don't sing or call like birds. Their sounds come from wing movement during flight. You'll hear a low-pitched buzz from larger species like the Common Green Darner, and a higher-pitched hum from smaller skimmers. When at rest, they are silent. The most distinct sound is the rapid clicking of wings when they chase prey or defend territory. Learning to distinguish these subtle noises can help you locate them without visual confirmation.

2. Where and when can you hear dragonfly sounds in Arizona?

The best places to hear dragonfly sounds in Arizona are near permanent water sources: ponds, lakes, slow-moving rivers, and marshes. Listen early in the morning (sunrise to 10 AM) and late afternoon (4 PM to sunset) when dragonflies are most active. During the heat of midday, many species rest and become quiet. In the higher elevations of the Mogollon Rim and White Mountains, the soundscape is more diverse with species like the Great Blue Skimmer. For reliable listening, visit the riparian areas of the Sonoran Desert after monsoon rains.

3. How to identify dragonflies by their wing sounds?

With practice, you can identify a few common species by ear. Larger darners (genus *Anax*) produce a deep, rhythmic buzz that changes pitch as they accelerate. Medium-sized skimmers (genus *Libellula*) have a faster, higher-pitched whir. Small pondhawks (genus *Erythemis*) make a soft, almost silent flutter. The key is to focus on the pitch and rhythm. A consistent low hum often means a patrolling male darner, while a staccato series of clicks indicates a territorial chase.

4. What is the most useful sound signal for a beginner?

The most useful sound signal for a beginner is the distinctive "wing rattle" of a male darner when it flies close to the water surface. This sound is louder and more metallic than regular flight. It often means the dragonfly is patrolling its territory. If you hear this rattle near a pond, stop and scan the area for a large, green-eyed dragonfly. This signal is your best clue that a darner is present, even if you don't see it at first.

5. When does sound matter most for spotting dragonflies?

Sound matters most during low light conditions or when dragonflies are silhouetted against the sky. Early morning or evening when visibility is poor, the hum of wings can reveal a dragonfly's path before you see it. Also, when dragonflies are high overhead hunting, sound is your only cue. In dense vegetation along the Salt River or Colorado River, hearing their buzz helps you pinpoint their location without pushing through brush.

6. One practical field note to keep your ear tuned to dragonfly sounds

Field note: Bring a small digital recorder or use your phone's voice memo app to capture a 30-second sample of ambient sound near any pond. Later, compare the noise of water, birds, and wind to isolate dragonfly wing beats. This practice trains your ear to filter out background noise. Over time, you'll recognize the signature hum of local species. I started doing this on my trips to Boyce Thompson Arboretum and now I can pick out a Green Darner from 30 feet away.
