Lophocampa caryae, the hickory tiger moth, hickory tussock moth, or hickory halisidota, is a moth in the family Erebidae and the tribe Arctiini, the tiger moths. The species is widely distributed in the eastern half of North America. In other species in this family, the caterpillars acquire chemical defenses from their host plants, so they are potentially toxic or unpalatable, but despite anecdotal claims that this species may also be venomous, no venom has yet been isolated or identified; adverse reactions are characterized as irritant contact dermatitis.
There is one generation per year. The larva, a caterpillar, is completely covered in long, hairlike setae arranged in spreading tufts. Most are white, but there are black tufts along the middle of the back, and four long black hair pencils, two near the front, and two near the back. There are black spots along the sides, and the head capsule is black. The hairs cause itchy rashes (contact dermatitis) in many people, particularly those prone to allergies, and may resemble exposure to urushiol. They are microscopically barbed and may rarely cause serious medical complications if they are transferred from... Wikipedia →

Rare
Under 5% of wildlife watchers report a Hickory Tussock Moth sighting in Boston on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 830th most-seen of the 1200 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Hickory Tussock Moth in Boston on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Hickory Tussock Moth sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 cities where we can rate Hickory Tussock Moth sightings, Boston ranks 4th at under 5%. The best odds are in Toronto (Canada, about 10%), Montreal (Canada, about 10%) and Detroit (United States, about 10%).

GBIF citizen-science records
It is estimated from how often the Hickory Tussock Moth is recorded against all the insects logged in Boston (9 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
