A frequent visitor to asters, the Arcigera Flower Moth has a dark, hairy thorax that deeply contrasts with its lighter midsection.
The Aricgera Flower Moth is a small nectar-loving insect that favors asters as a food plant for its young caterpillars. The brown moth may have hues of purple or red on the middle part of its forewings. A distinct pattern is shared by all adults despite differences in overall shade. Two obvious arcs decorate the wings near the 'shoulders'. Each forewing has a single, white curved line that separates the darker brown head, thorax, and upper wing from the lighter middle band of color, which may be brown, lavender, or maroon. A straighter white line crosses the wings closer to the bottom. Males have hindwings that are yellow with a wide black border. A white fringe runs along the bottom edge. Females have hindwings that are completely black, but also share the white fringe.
Though adults drink nectar from asters, they also visit other flowers. The brown caterpillar has wide, ivory or tan stripes on each side of the body that have a row of black dots in the center. The fleshy body is sparsely covered in fine, light hairs. Larvae feed on varieties of asters. Look for adults at dusk or at night near flower fields, especially ones that grow their offspring's favorite food plant.

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