Synonyms and other taxonomic changes
Acrolepiopsis incertella (Chambers, 1872)
described in 1872 by Chambers, who originally placed it in genus Heribeia
Formerly placed in family Plutellidae.
Numbers
There are seven species of the genus Acrolepiopsis in America north of Mexico.
Size
Wingspan about 11 mm, based on photo by Jim Vargo at MPG.
Identification
Adult: forewing slender, grayish-brown with reddish iridescence and small white triangular patch part-way along inner margin; distinct notch part-way along outer margin; hindwing brownish-gray, paler than forewing, with dark veins and whitish shading toward base.

Larva: body pale green with sparse short hairs.
Range
Heppner (2003) reported the range to include New Hampshire to Florida(1), west to Texas and Illinois. (2)
Season
The main flight period appears to be February to September. (3)
Heppner (2003) reported March and May in Florida. (2)
MJ Hatfield recorded a the emergence of a specimen from Iowa 10/29/21, BugGuide Photo#2089881. "... for A. incertella, this represents new information on host plant, larval feeding mode, and phenology. It also impacts the reliability of sight identifying spring-occurring adults..." - Terry Harrison (pers. comm. 9/8/22).
Food
The larvae feed on carrionflower or greenbrier (Smilax spp.), especially Bristly Greenbrier (S. tamnoides); also reported on lily (Lilium spp.)
Life Cycle
The larval hostplant terminal leaf is rolled and tied together at the edges by a larva, which lives and feeds inside the rolled leaf in early spring. After the larva finishes feeding, it vacates its rolled-leaf shelter and spins a meshwork silken cocoon, inside which it pupates. Adults emerge in late May and overwinter. One generation per year.

The similar Acrolepiopsis heppneri is a fall species, being present as a larva in September and October, and emerging as an adult in October.
