Banded Tussock Moth (Halysidota tessellaris): What It Is and When to See It

Halysidota tessellaris · Erebidae

The Banded Tussock Moth (Halysidota tessellaris) is a soft, pale-yellow tiger moth in the family Erebidae, recognized by translucent tan wings crossed by faint bands and a distinctive thorax striped with iridescent blue-green and black. It is common in the eastern US and Canada, with the most records in New York, Virginia, North Carolina, Maryland and West Virginia. Adults fly in mid to late summer, peaking from July through September, and they come readily to lights at night.

How to identify the Banded Tussock Moth

The Banded Tussock Moth is a medium-sized moth with a wingspan around 3.5 to 5 cm (about 1.4 to 2 inches). The wings are pale, semi-translucent tan to yellowish, crossed by several faint, slightly darker bands, giving the moth a soft, washed-out look. The best field mark is on the body: the thorax is striped lengthwise with shining blue-green and black, a subtle but reliable detail to check. Despite the "tussock" in its name it is a tiger moth, not a true tussock moth, so the adult lacks the dramatic tufts of an Orgyia.

Where the Banded Tussock Moth lives

This is a common moth of eastern deciduous woods, forest edges, parks and wooded suburbs. The open records show it most concentrated in New York, Virginia, North Carolina, Maryland and West Virginia. Wherever there are hardwood trees for the caterpillars to feed on, the adults are likely nearby, which makes this one of the more frequently seen tiger moths at summer lights in the East.

When the Banded Tussock Moth flies

The adults are creatures of mid to late summer. In the records they peak from July through September, overlapping National Moth Week (July 18-26, 2026). A warm, calm night anywhere in that window gives you a strong chance of seeing one at a light.

Caterpillar, host plants and life cycle

The caterpillar is fuzzy and variable, usually pale yellow to gray with long whitish or black hair pencils projecting from each end. It feeds on the leaves of many hardwoods, including oak, hickory, ash, birch, elm and willow. Like other hairy caterpillars its hairs can irritate sensitive skin, so don't handle it. The species overwinters as a pupa in a hairy cocoon and emerges the following summer, generally completing one generation per year through much of its range. Note that the caterpillar can be hard to tell from look-alike tussock larvae, so the striped-thorax adult is the more reliable identification.

How to see a Banded Tussock Moth at night

This moth comes well to light, so a summer light session is the easiest way to find one. Hang a white sheet and shine a UV (blacklight) or mercury-vapor lamp on it; UV and short-wavelength light bring in far more moths than a white LED porch bulb. Moths collect at lights because the bright source disrupts their flight orientation rather than drawing them in as a target, so keep the light steady against a pale sheet and check across the first hours after dark. July and August are prime. For timing, see our good night for moths guide, and compare with the look-alike Hickory Tussock Moth.

Frequently asked

Is the Banded Tussock Moth a true tussock moth?
No. Despite the name it is a tiger moth (subfamily Arctiinae) in the family Erebidae, not a true tussock moth, so the adult lacks the dramatic tufts seen on Orgyia species.
What is the easiest way to identify the adult?
Look at the thorax: it is striped lengthwise with iridescent blue-green and black. Combined with the pale, faintly banded translucent wings, that thorax stripe is the best field mark.
When do Banded Tussock Moths fly?
They peak from July through September in the records, overlapping National Moth Week (July 18-26, 2026). Mid to late summer is the best time to find them at lights.
Can I handle the caterpillar?
It is best not to. The caterpillar's hairs can irritate sensitive skin. Look without touching, and it does not sting.
Where is the Banded Tussock Moth most common?
The open records show it most in New York, Virginia, North Carolina, Maryland and West Virginia, but it ranges widely across the eastern deciduous forest.
