Are There Cicadas in Vermont?

Where Cicadas Are Found in Vermont

The few cicadas present in Vermont are concentrated in the state's southernmost counties, particularly Windham and Bennington Counties near the Massachusetts and Connecticut borders. These regions have warmer microclimates and mature forest patches that occasionally support annual cicada species. The Connecticut River valley in southern Vermont provides some suitable habitat, though populations remain sparse and unpredictable. The Green Mountains in central and northern Vermont are generally too cool for sustained cicada populations. The Lake Champlain region, though relatively mild, does not consistently host cicadas. Most Vermont cicadas occur in oak and hickory forests at lower elevations in the southern part of the state. Even in these favorable zones, cicadas are far less abundant than in adjacent Massachusetts or Connecticut. Learn more aboutVermont wildlifeto find other insects and animals in the state.

Season and Timing in Vermont

If cicadas appear in Vermont, they typically do so in late July through August when summer temperatures peak. Vermont's cool nights and short growing season mean that even during warm years, cicada emergences are weak compared to regions further south. Periodical cicadas are extremely rare in Vermont; the state lies outside the established brood zones of the 13-year and 17-year Magicicada cycles. Some years may pass with no cicada observations at all, while other warmer summers might produce a few scattered calls in the southernmost towns. The unpredictability of Vermont cicada activity reflects the state's marginal climate for these insects. Annual cicadas, when they do appear, have a brief emergence window of just two to three weeks before temperatures drop and populations dwindle. Late spring frost events can also prevent cicada nymphs from successfully completing their underground development and emergence. For more on cicada in Vermont, see ourVermont cicada guide.

How to Identify a Cicada

Vermont cicadas, when present, are medium-sized insects measuring 1 to 1.5 inches long. They typically display brownish or tan wing covers and strong bodies built for clinging to tree bark. Their most distinctive feature is their use of sound to communicate; males produce loud buzzing or whining calls that can carry considerable distance even from single individuals. Cicadas have relatively short antennae and large compound eyes positioned on either side of their heads. Their long, straw-like beaks are used to pierce plant tissues and extract xylem fluid. Wings are held tent-like over the body when at rest, giving them a somewhat tapered silhouette. The most reliable identification feature is the sound itself; once heard, a cicada's call is unmistakable and serves as confirmation that these insects have successfully reached your area. Molted exoskeletons left behind on trees are also distinctive and often collected as curiosities. You can also browseVermont wildlife.

Where Sightings Concentrate in Vermont

Rare Vermont cicada sightings cluster in Windham County's mature deciduous forests, particularly around towns like Brattleboro and Hinsdale. The Monadnock region straddling the Vermont-New Hampshire border occasionally reports cicada activity, especially in oak-dominated stands. The Connecticut River valley, particularly the warmer microhabitats near Guildhall and Guilford, has produced occasional reports. Fort Independence Park near the Massachusetts border and the lower elevations of the Green Mountains near the state line offer the best odds for cicada encounters. Warmer residential areas with mature shade trees in Brattleboro and Bellows Falls may occasionally host cicadas. Swamps and wetlands are less likely to support cicadas; these insects prefer drier oak and hickory forests. Even in optimal locations, successful cicada observation in Vermont requires patience and luck, as populations are simply too small and sporadic to guarantee sightings.

Typical Cicada Behavior

Vermont cicadas, like all cicadas, are focused entirely on feeding and reproduction during their brief adult lives. Males produce their characteristic buzzing or droning sounds by rapidly vibrating specialized structures called tymbals located on their abdomens. These calls can reach surprising volumes and serve to attract females for mating. Males may call throughout the warmest parts of the day, typically midday through early afternoon. Cicadas spend their time clinging to tree trunks and branches high in the canopy, extracting fluids from trees through their piercing beaks. Females lay eggs in slits cut into small branches; the emerging nymphs drop to the soil and burrow down to feed on root fluids. Underground development takes multiple years before nymphs emerge as adults. Vermont's cool climate may extend the underground development period compared to warmer regions. Once above ground, adult cicadas live only four to six weeks before dying of natural causes.

Coexistence and Safety Notes

Cicadas are entirely harmless and beneficial members of Vermont's ecosystem. They do not bite, sting, or transmit any diseases. If handled roughly, they might attempt to pierce skin with their beaks in search of plant fluids, but this is rare and causes no injury. Cicadas cause only negligible damage to trees during egg-laying, and any twig damage is temporary and does not threaten tree health. Because Vermont cicada populations are so small, they create no noise nuisance and pose no agricultural problems. These insects are food for various birds, spiders, and parasitic wasps, so their presence benefits the food web. Aguide to cicadas in Vermontprovides more detailed information. If you encounter a cicada in Vermont, consider yourself fortunate, as it indicates either a particularly warm year or unusual climatic conditions favoring this rare visitor from more temperate zones.

Species People Confuse with Cicadas

The most common confusion in Vermont involves cicadas and grasshoppers, which produce sounds using completely different mechanisms. Grasshoppers have elongated bodies with prominent hind legs built for jumping, while cicadas are compact with shorter legs designed for clinging to bark. Locust swarms, despite their name, are actually grasshoppers in a swarming phase and look nothing like cicadas. Katydids are also frequently confused with cicadas, though katydids are orthopterans with longer antennae and flatter bodies. Cicada killers are large wasps that prey on cicadas, and people sometimes mistake the wasp for the cicada itself. In Vermont, where cicadas are so rare, most confusion is purely speculative since few people have encountered a real cicada to compare against other insects. Reviewing photographs and sound recordings online can help confirm whether an observation is actually a cicada or another sound-producing insect.

Frequently Asked Questions About Cicadas

Q: Are periodical cicadas coming to Vermont? A: Periodical cicadas do not have established brood cycles in Vermont. The state is outside the range of the 13-year and 17-year Magicicada broods, so mass emergences will not occur.

Q: Why is Vermont so quiet compared to other states with cicadas? A: Vermont's cool climate and shorter growing season create conditions that are marginal for cicada survival. Only annual species survive sporadically in the far south, and populations are tiny even in ideal years.

Q: What should I do if I hear a cicada in Vermont? A: Report it to local naturalist groups or the Vermont Fish and Wildlife Department. Any confirmed cicada sighting in Vermont is notable and of scientific interest.

Q: Can cicadas hurt my trees? A: Cicadas cause only minor, temporary damage during egg-laying and pose no real threat to tree health. Vermont's cicadas are so rare that tree damage is not a practical concern. Visit thenational wildlife hubto learn about other wildlife across the United States.
