SPOTTED in New London!

, , , ,

During preparations for this year’s fall bird migration count, Dr. Adam Mitchell of Tarleton State University and Catalina Berry, a Ph.D. student and former lead of the 2024 migration team, observed an adult spotted lanternfly on the ground in New London, just a block from the ferry. This marks a concerning sign that the invasive species is present close to the island and could spread here.

 

The spotted lanternfly (Lycorma delicatula) is a destructive invasive insect tha tposes a significant threat to both agriculture and native ecosystems. Although it is native to Asia, it has spread rapidly through the northeastern United States in recent years. The insect feeds on the sap of plants, with a strong preference for the invasive tree-of-heaven, but it is known to consume more than

100 plant species. These include grapevines, fruit trees, hardwoods such as maples and oaks, and a wide range of ornamental plants and vines. Infestations can cause serious damage to crops, reduce the health of trees, and disrupt ecological balance.

While the insect is not dangerous to humans or pets, it spreads quickly and often hitchhikes on vehicles, firewood, outdoor furniture, and other materials. For this reason, the community’s vigilance is super important in preventing its spread to our island.

What You Can Do to Help Prevent the Spread

1. Check your belongings and vehicles
Before traveling to or from the island, inspect your car, boat, luggage, and any outdoor equipment for spotted lanternflies, egg masses, or nymphs.

2. Look for egg masses
From fall through early spring, females lay egg masses on flat surfaces such as trees, rocks, vehicles, patio furniture, and even outdoor gear. Scrape and destroy any you find.

3. Avoid moving firewood
Do not bring firewood or other untreated outdoor materials onto the island, as these can easily carry egg masses or hidden insects.

4. Be vigilant in your yard
Check trees and plants regularly, especially grapes, fruit trees, maples, and tree-of-heaven, which are common hosts.

5. Report sightings immediately
If you see a spotted lanternfly, take a clear photo and report it to both the Fishers Island Conservancy and the New York State Department of Environmental Conservation (NYSDEC). Reports can be submitted through NYSDEC’s invasive species survey

6. Kill the insect if possible
Spotted lanternflies are not harmful to people or pets. Stomping or capturing them on sight is one of the most direct ways to slow their spread!

 

2025 Fall Migratory Bird Count Results

  Announcing the Results of the Fall 2025 Migratory Bird Count

We are excited to share the results of this year’s Fall 2025 Migratory Bird Count. With the help of our wonderful volunteers, we recorded 41 bird species, which is right in line with the long-term average of about 40 species for the fall season.

This year’s count had some exciting highlights. A bobolink was recorded calling in flight over the Parade Grounds, and we saw more ruby-throated hummingbirds and northern harriers than in previous years. At the same time, a few species were noticeably absent, including yellow warblers, most sparrows aside from the song sparrow, and the swallows that are usually common on the island.

The slightly lower number compared to last year’s 45 species and 50 species in 2023 may be explained by a few different factors. As many participants noted, the season felt quieter overall, since birds are less vocal during fall migration than they are in the spring. Weather and climate patterns also play a role. Prolonged summer temperatures, drought in New England, and the effects of El Niño across North America can all influence when different species decide to move south.

In addition to the official count, we also kept a running count throughout the weekend, which brought our total up to 52 species. Beyond the birds, we recorded around 26 monarch butterflies and were greeted by fields of goldenrod, both promising signs of migration still to come.

One of the best parts of this year’s event was the community that came together! We were thrilled to welcome 13 participants on Saturday, which was our largest turnout yet. Thank you to everyone who joined us and brought such energy and enthusiasm to the day. And to our regulars who couldn’t make it this year, you were missed!

Why Bird Counts Matter

Annual bird counts give us a chance to connect with nature while also helping us better understand the rhythms of migration and the health of our local ecosystems. Each year of observations adds to a long-term record that supports conservation efforts and deepens our appreciation for the island’s biodiversity.

Here is the list of species we encountered in our Fall 2025 Migratory Bird Count.

Silver Eel–Race Point Coastal Trail Opens with Dedication to Janet Harvey

, , ,

The Fishers Island Conservancy is proud to be part of the newly opened Silver Eel–Race Point Coastal Trail and the dedication of the Janet Harvey Sanctuary—two projects that highlight what’s possible when the island comes together around a shared vision for conservation and public access!

This new trail links Silver Eel Cove to Race Point and travels through a mix of restored and protected landscapes, including Ferry Park, where the Conservancy has led extensive habitat restoration and native planting efforts over the past several years. It’s an area we’ve worked hard to return to native coastal meadow and pollinator-friendly habitat, and we’re excited to now have it accessible as part of a continuous public trail on the island’s West End.

One key section of the trail travels over the 1,200-foot berm created by the Fishers Island Ferry District in 2022. That project used over 2,500 cubic yards of clean sand dredged from Silver Eel Cove to build a graded berm between the high tide line and the parking area. The Ferry District invited the Conservancy to advise on stabilizing and beautifying the berm and we were thrilled to recommend, source, and sponsor the planting of native grasses. Today, that stretch is lush, protected, and an important part of the trail corridor.

The trail winds from the Lighthouse Works Public Art installation, through Ferry Park and the Ordnance, into the newly established Janet Harvey Sanctuary, and onward to the meadows, shorelines, and historic sites at Race Point.

The five-acre Janet Harvey Sanctuary was made possible through a license agreement with the Fishers Island Waste Management District. It protects a section of coastal habitat along with historic Fort Wright structures, offering views over Long Island Sound and back toward the Fort’s inland batteries. Named in honor of Janet Hardie Harvey, the sanctuary reflects her commitment to both the natural world and ensuring island landscapes are available to all.

This project is the result of collaboration across the Museum, the Waste Management District, the Ferry District, the Conservancy, and Brad and Mary Burnham, owners of the Ordnance property. It’s the kind of partnership work that’s essential to sustaining the island’s ecological and cultural heritage.

The community is invited to join the dedication and opening walk this Sunday, August 10, at 9 AM at the Ordnance (between the Paddle Courts and the FICC). Light breakfast, coffee, and brief remarks will be followed by a trail walk.

Later in the day at 4 PM, Museum Director Pierce Rafferty will give a talk on the island’s conservation history.

We’re proud to have contributed to this effort and look forward to seeing the community on the trail!

Meet the Hickory Horned Devil

, , ,

juvenile stage by Kristen Peterson

The Hickory Horned Devil is the largest caterpillar in North America and one of the most unforgettable. It goes through a dramatic transformation, beginning life as a small, dark, spiky creature and growing into a bright green, six-inch-long caterpillar with vivid red horns and a prehistoric look. Despite its intimidating appearance, it is completely harmless!

Early Life

In its early stages, the Hickory Horned Devil is easy to miss. Young caterpillars are dark-colored with long, fine spines and short horns that often have spoon-shaped tips. They may have reddish coloring along their midsection and spend this time feeding on leaves in the canopy of native trees like sumac, walnut, sweetgum, and hickory. This color phase is brief but fascinating, and those familiar with the species may still recognize it even at this early stage.

Growing Up

With each molt, the caterpillar grows larger and brighter. Eventually, it reaches its full size, glowing green with black-tipped red horns, and covered in subtle blue and yellow markings. This stage typically peaks in August, when the caterpillar prepares for the next chapter of its life cycle.

 

Pupation stages by Richard Stickney

As summer winds down, mature Hickory Horned Devils leave the trees and begin to crawl across the ground, searching for soft soil. Once they find a suitable spot, they burrow underground to pupate. Unlike many other moths, they do not spin a cocoon. Instead, they remain underground in a tough, smooth pupal shell where they will spend the winter.

The Final Form: Regal Moth

The following summer, if all goes well, the adult moth emerges. Known as the Regal Moth or Royal Walnut Moth, this beautiful insect is one of the largest moths in North America. It has rust-orange forewings with cream spots and soft gray hindwings with orange stripes. While stunning in its own right, the adult moth lives only for a short time and does not eat—it exists solely to reproduce and continue the cycle.

Why It Matters

The Hickory Horned Devil is not just a fascinating insect… it is also a valuable part of our native ecosystem! Its presence on Fishers Island indicates healthy host plant populations and minimal pesticide use. Like many native caterpillars, it provides food for birds and other wildlife and plays a role in supporting broader biodiversity!

We are fortunate to spot this species on the island. Whether you’re walking a trail or tending your garden, keep an eye out for these incredible creatures and appreciate their place in our shared landscape.

If you’ve photographed one on Fishers Island, we’d love to see it! Share your sightings with us and help us celebrate the wildlife that makes this place so special.
