Pale Beauty

The Pale Beauty's sculpted hindwings, misty green hues, and pearly luster fuse together in this comely moth.

Palest shades of green veil the wings and body of the Pale Beauty. Though individuals often vary is depth of color, females are generally larger than males. Two prominent lines cross the wings. The shorter line is near the head and its outer edges bend toward the moth's face. A darker, mossy green underlines it. The longer line crosses the lower half of all four wings with a similar dark, mossy green line above it. This species is found as far north as the Arctic, though it spends only a few weeks in the summer in that colder region. In the warmer, southern region, it is active from late spring through early autumn.

Females lay a clutch of round, yellow eggs that become red over a few days. Larvae are mimics of twigs and branches. Their slender bodies stretch along tree branches and forms little loops as they inch their way around a tree. A mottled brown coloring aids in camouflaging them, and small hairs fringe the bottom edges of their bodies. These caterpillars feed on the leaves of various deciduous trees like alder, ash, beech, birch, elm, oak, poplar, and willow. Each year, one or two broods can be produced.

The Pale Beauty can be found where host trees are growing such as forests and woodlands in wilderness as well as more developed areas.

Butterfly and Moth Anatomy

Antennae: Butterflies and Moths have a pair of antennae on the head used as sensors.

Head: The head is home to the insect's eyes, antennae, and proboscis.

Thorax: Home to the three pairs of legs as well as vital internal organs.

Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.

Forewing: The upper, forward wing pair used for flying.

Hindwing: The lower, rearward wing pair used for flying.

NOTE: Butterflies and Moths are part of the Lepidopteran order as they share many similarities.
