Though individuals vary is shade, the main identifying marks on the Confused Eusarca are as clear as crystal.
Some Confused Eusarcas are more brown than others. Some have a tan or white base color with hints of yellow. These variations may explain the confusion in their name. All are peppered with small flecks of brown all over the wings. The most obvious identifiers for this species are on the large forewings. Each wing has a curved brown line near the head. Farther down the outer edge of each wing is a small, distinct dot. The lower half of each wing has a thin brown line that crosses it, ending near the tip. This line is continued on the small hindwings and is visible when the wings are resting flat. The hindwings also have a distinct dot on them above that line that is seen when the wings are spread wide open. The rounded edges of the wings come to delicate points.
Caterpillars of the Confused Eusarca look like short, brown twigs. These larvae mimic twigs by hanging onto a branch with one end and stiffening the body away from the branch. They eat from plants like aster, dandelion and goldenrod. Such host plants are usually found in meadows, fields, and gardens, so look for flying adults and their inconspicuous caterpillars in these areas from spring through most 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. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Butterfly and Moth Anatomy

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.
