Lambdina fiscellaria
The Hemlock Looper Moth is a small, fuzzy moth that loves to flutter around at night. Its caterpillars are green and can be found munching on hemlock trees, making them special little eaters!
Habitat: Forests
The Hemlock Looper Moth has pale grey to tan wings, often marked with faint, wavy dark lines that help it blend into tree bark or lichen. Its slender body is similarly colored, making it well-camouflaged. This pattern distinguishes it from solid-colored moths.
