The deep brown and tan markings on the male Baltimore Snout's wings resemble a luxurious cloak.
Also called a Baltimore Hypena Moth, the Baltimore Snout has a triangular shape. The snout is actually two labial palps on the front of the head that extend forward and together; it is not a nose or trunk. The male is darker and more two-toned than the female. She has almost a gray hue over her wings. She is paler where he is dark, and she is darker and more patterned where he is light. A blackish streak running down next to the body on the forewings is more visible on the female because of her paler shade. An angled dark streak stretches to each wing tip on both sexes. This is a nocturnal moth, but it will come to lights at night.
Caterpillars feed on the leaves of maple trees, so look for both larvae and flying adults in or near deciduous forests. They are a chartreuse green with orange or red bands between their segments. Depending on maturity, a ring of black or orange dots on each segment may also be visible. The last pair of prolegs are at the tip of the abdomen and flare out in a V-formation. Two or more broods can be produced each year, and they appear in summer through autumn. Adults are active in early spring in the southern, warmer part of their range and remain so until almost the end of autumn.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory.

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.
