Halysidota tessellaris, also called the pale tiger moth, banded tussock moth, and tessellated halisidota, is in the family Erebidae and the tribe Arctiini, the tiger moths. The species was first described by James Edward Smith in 1797. Like many related species, adult moths have chemical defenses acquired from its host plants, in this case, alkaloids. Larval behaviors suggest that they are chemically protected; they have not been analyzed for alkaloid content.
This moth is found in North America from southern Canada south through Texas and central Florida. One generation per year occurs in the north, and two or more occur in the south. Eggs are laid in masses on the undersides of leaves.
Caterpillars are covered with long setae, in tufts. They vary from yellowish and orange through dark gray. Extra long hair-pencils of white, black, and/or orange occur at both the front and rear of a caterpillar. Larval head capsules are bright orange. In the north, mature caterpillars are found from July to frost. Caterpillars frequently rest on the upper surface of leaves, and though not gregarious, they are very conspicuous.

Possible
About 30% of wildlife watchers report a Banded Tussock Moth sighting in Congaree National Park on a given day, based on 50 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 145 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
October
In that month about 60% of wildlife watchers report a Banded Tussock Moth in Congaree National Park on a given day, against under 5% in August and November–May, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Banded 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.
Yes
Of the 6 parks where we can rate Banded Tussock Moth sightings, Congaree National Park has the highest daily chance: about 30%. Next come Great Smoky Mountains National Park (United States, about 30%) and Shenandoah National Park (United States, about 20%).
Same family: Erebidae
The closest relatives of the Banded Tussock Moth that you can see in Congaree National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are White-Marked Tussock Moth (about 30%), Fall Webworm Moth (about 30%) and Giant Leopard Moth (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Banded Tussock Moth is recorded against all the insects logged in Congaree National Park (50 verified sightings from 2019 to 2026), 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.
