Introduction to Isabella Tiger Moth
People know the caterpillar, not the moth. Pyrrharctia isabella is built so the larva can stop, freeze, and continue, which is why a woolly bear on a snowy path is not lost.
How to identify a Isabella Tiger Moth
- Adult: dull yellow-orange moth with sparse black spots, wingspan about 45 mm
- Larva: dense black-and-rust bands of hair, the woolly bear

- Overwinters as a larva, not as a pupa or egg
Why Isabella Tiger Moth are interesting
- The rust-band width is folklore for winter severity and is not a forecast. It varies with age and moult.
- The larva produces cryoprotectants and can survive being frozen solid.
- It is common across most of North America and is one of the caterpillars children are told not to fear.
- The adult is nocturnal and easily overlooked; almost every sighting that matters is the larva.

05
Why this diet?
Larvae eat a wide range of low plants and garden weeds. Adults take little or no nectar. The winter walk is not feeding; it is searching for a place to tuck in.
06
Activity, rest, and lifespan
Larvae walk by day in autumn. Adults fly at night in late spring and summer after pupation.
Most of a year as a larva, including the winter. The adult lives a week or two.
07
Isabella Tiger Moth reproduction
Eggs are laid on low plants in summer. The larva feeds, overwinters, feeds again briefly in spring, then pupates.
Adult males have slightly finer antennae. The woolly-bear bands are not a sex mark.
08
Predators, threats, and defense
Birds take some larvae; the dense hairs and the habit of curling into a ball are the defence. Adult moths are taken at lights by bats.
