Residents across Connecticut are reporting rising numbers of the invasive spotted lanternfly, with the largest concentrations so far occurring along the state’s shoreline, the Connecticut Agricultural Experiment Station said Friday.
What residents should do now
State entomologists say the insects are in their nymph stages now and that sightings will increase as they mature into adults later this summer. Because the bugs move mainly by hopping and hitchhiking on vehicles, furniture and plant material rather than sustained flight, officials say public vigilance is the best tool to slow their spread.
- Report sightings to local extension services or the Connecticut Agricultural Experiment Station.
- Remove and destroy spotted lanternflies encountered on property — adults and nymphs — following local guidance.
- Inspect vehicles and outdoor items after travel, especially if you come from affected areas or shoreline communities.
"If you see a spotted lanternfly, dispatch it," Dr. Gale Ridge of the Connecticut Agricultural Experiment Station said.
Scope and local responses
Dr. Gale Ridge, an entomologist at the state station, told reporters that calls about the pest have become a large portion of the office’s workload. Town officials in Newington recently removed two saplings after discovering infestations, and local leaders are encouraging residents to check trees and report sightings to municipal offices.
Ridge said the population will not decrease until natural predators establish control, a process that could take time. In the meantime, community action is critical.
Life cycle and timing
Understanding the spotted lanternfly lifecycle can help homeowners decide when to check yards and trees. The table below summarizes the stages and what to look for.
| Stage | Timing in Connecticut | What to watch for |
|---|---|---|
| Nymph (early) | Spring–early summer | Small, black-and-white hopping juveniles |
| Nymph (late) | Mid-summer | Red and black juveniles, larger but wingless |
| Adult | Late summer–fall | Winged insects with striking spotted forewings |
Officials stress that while the insects are conspicuous, they do not yet have an established level of biological control in Connecticut. Ridge noted that public reports are critical to tracking spread and guiding responses.
Municipalities and the state encourage residents to consult local extension services for removal instructions and to avoid transporting firewood, plants or yard waste from affected areas. Those who find suspected specimens should photograph the insect, note the location, and report it to the Connecticut Agricultural Experiment Station or their town office.
As sightings increase, shoreline towns are expected to remain among the most affected areas. Local governments are preparing outreach and removal actions to limit damage to ornamental and native plants.
