Jericho Vermont Butterflies: Species Not Yet Recorded & How to Help the Vermont Butterfly Atlas

Jericho residents: let’s document our butterflies—together.

Right now, there are butterfly species known from across Vermont that have never been recorded in Jericho. That’s not because they aren’t here—it’s because no one has documented them yet. This is a real, local data gap we can close as a community.

By observing and posting butterflies from your yard, road, trail, or field, you can directly strengthen Jericho’s record in the Vermont Butterfly Atlas—a statewide effort tracking species distribution and abundance. Every observation counts. A single clear photo from your backyard could be the first verified record of that species in town.

We’re looking for community scientists, naturalists, photographers, families, and anyone who spends time outdoors in Jericho to take part. No special expertise required—just curiosity and a willingness to look closely.

Below is a comprehensive list of butterfly species recorded in Vermont but not yet documented (via iNaturalist) in Jericho. This is our Jericho target list—the species we have the best chance of adding to Jericho’s record with focused effort this season.

Further below, you’ll also find a full list of all butterfly species recorded across Vermont. Each species includes a VAL (Vermont Atlas of Life) hotlink for quick access to identification details, flight periods, habitat associations, and host plants.

How You Can Help

• Focus on Jericho - or elsewhere in Vermont - but why go further when we have so much to enjoy here!
• Visit sites at least once per month (May–September)
• Photograph all butterflies observed (even common species)
• Upload records to eButterfly or iNaturalist
• Prioritize species on the “not yet recorded in Jericho” list
• Note habitat, behavior, and host plant associations when possible

Jericho has the habitat. The species are out there. What’s missing is the documentation.

Let’s fix that—one observation at a time.

Why This Matters

• Creates a baseline we—and future residents—will rely on decades from now
• Supports conservation prioritization and trend analysis
• Even a single well-documented observation can meaningfully expand what we know about butterflies in Jericho.

Need assistance? If you’re seeing butterflies in your yard but aren’t able to photograph or upload them to iNaturalist, contact Bernie—he can photograph and post observations in yout yard so they count toward the Vermont Butterfly Atlas.
