Two sets of zig-zag lines cross the wings of the Angulose Prominent, a furry, brown woodland moth.
Most Angulose Prominents are some shade of brown. The thorax and parts of the legs are wildly hairy. An orange-brown or copper-colored patch sits near the 'shoulder' joint and is usually part of the sharply angled lines crossing the wings. Areas of white or pale brown may also decorate the forewings. It has a large range, spanning across much of the eastern part of the continent, but it is not always a common sight. It prefers mature woods and forests where its coloration easily blends in with the oak trees.
Fleshy caterpillars may be green or a rosy shade of pink with twin stripes running along the 'back'. They feed on oak leaves, which are abundant within their range. Like a cobra snake, a scared or threatened caterpillar raises its head in a striking posture, but it does not bite or sting, so the behavior may serve to confuse the threat. Two or more broods can be produced each year.
Scientific Name: Peridea angulosa
Butterfly or Moth
Size (Adult; Length): 35mm to 45mm (1.37in to 1.76in)
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. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
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.
