Adult Markings: The following description is based primarily on that of Braun (1930). The head and thorax are brown and the face whitish. The antenna is uniformly black with whitish annulations along its entire length. The labial palp is white, and the second segment has a sub-basal and sub-apical annulation. The third segment is narrow and noticeably longer than the second segment. There are three black bars along its length, and the anterior edge is narrowly white with a fine black line edging it on each side. The ground color of the forewing is bright brown and sometimes has a roseate tinge. The are three large, dark brown marks. The first is a broad, slightly oblique bar that begins at the base of the costa and extends to the dorsal margin. The posterior edge is usually margined with a thin line of white scales. A similar bar begins at about two-fifths and runs approximately parallel to the first. It terminates before reaching the dorsal margin, and is often hooked at the end. The last mark is a broad-based costal patch at about three-fourths that narrows just before ending near the middle of the wing. The costal patch has a whitish patch immediately behind it that often has a few brown scales near the center. The areas between the brown marks are pale to grayish white, and dusted with varying amounts of brown scales. Some specimens have a suffusion of rosy scales in this region. Two small, dark brownish-black spots are usually evident near the middle and between the second dark bar and the dark costal patch. A blackish longitudinal streak is present beyond these that is above the white costal patch at four-fifths. The area around the tornus is often suffused with rosy coloration. Patches of small black and white scales are present along the costa just below the apex. There is often a line of dark grayish scales at the wingtip that extends around the apex and along the termen, and a parallel gray band posterior to this in the cilia. The hindwings and cilia are dark gray, and the legs are boldly banded with black and white. This species is similar to A. roseosuffusella, but the latter has dark bands that strongly contrast with the white regions that are in between, along with a narrow white bar at the wing base. The wing base of A. lespedezae is typically solid brown at the base.
Wingspan: 11-13 mm (Braun, 1930)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larvae feed on species of Lespedeza within webs that are usually spun near the tops of plants. Braun (1930) noted that the young larvae spin webbing on stems. They then expand the web to include a nearby leaf, where they initially only feed on the underside. As they age, the larvae begin consuming entire leaves -- typically within an enlarged webbing that may envelope several leaves. The young larvae are greenish and the older larvae grayish green. The prothoracic shield is black and the body is marked with a series of longitudinal red lines.
Distribution in North Carolina
Distribution: Aristotelia lespedezae is found in the eastern US, primarily in Kentucky and southern Ohio, but with scattered populations elsewhere, including West Virginia, Oklahoma, Tennessee, and North Carolina. Many records need to be carefully checked for correct identification. As of 2021, our records are all from the Piedmont.

Flight Comments: Adults have been observed from May through October in areas outside of North Carolina. As of 2021, our records are from late-May through late-July. Larvae that Braun (1930) collected in Kentucky and Ohio yielded adults in less than a month.
Habitats and Life History
Habitats: This species exploits lespedezas, which are typically found in sunny or partially sunny sites with mesic to drier soils. Typical habitats include roadways and logging roads, woodland borders, weedy fields, the edges of agricultural fields and open woodlands.
Larval Host Plants: The only known host is Hairy Lespedeza (Lespedeza hirta), but other lespedezas are probably used.
Observation Methods: The adults are attracted to lights. More information is needed on the host plants and the larval ecology, so we encourage individuals to rear adults and document host use.
