What reliable physical marker distinguishes the Isabella Tiger Moth larva from the Giant Leopard Moth caterpillar?
Answer
The specific black-and-brown banding pattern
While both the Woolly Bear and the Giant Leopard Moth caterpillar are hairy species, accurate identification relies on specific visual markers to avoid confusion, especially regarding potential skin reactions (though the Woolly Bear is harmless). The defining characteristic of the *Pyrrharctia isabella* larva is its pattern of relatively even, distinct black and reddish-brown segments banded circumferentially. In contrast, the Giant Leopard Moth caterpillar presents a different appearance, typically being almost entirely black and considerably hairier, lacking the consistent, specific bicolored banding of the Isabella Tiger Moth larva.
