Synonyms and other taxonomic changes
Cosmopterix lespedezae Walsingham, 1882
Cosmopteryx lespedezae Walsingham, 1882
Forewing length 4.7 mm (1).
See description and figures here.
South Carolina, Kentucky, Ohio, Arkansas, Texas (Hodges, 1978 (2)), and Mississippi (1).
Adults have been collected from early July to mid-September (1).
"Larvae feed on various Fabaceae species, including Lespedeza and Desmodium species" (1).
Life Cycle
"Braun (1930) (as C. magophila sic!), gives the following description of the larval habits on Desmodium sp.: 'The mine begins in the midrib, spreading outward and upward between two lateral veins; in that part of the early mine adjacent to the lower of the lateral veins between which it lies, the parenchyma is left in narrow transverse bars, giving the mine a very characteristic aspect; as the mine increases, it extends beyond the confines of the two veins, with irregular projections and parenchyma all consumed. Pupa formed within the mine beneath the transverse bars, which are here lined with silk forming a tubular pupal chamber'" (1).

Cosmopterix teligera is very similar, but differs slightly(?) in antennal banding pattern.
Cosmopterix clemensella: "The key in Koster (2010) relies on the clemensella forewing being greyish brown and lespedezae dark brown, which is very subjective and hardly accurate. Otherwise clemensella should have a 4x larger outer dorsal spot than the opposite costal spot (lespedezae is 2-3x). I have also found this to be an unreliable character. The only possible distinguishing character I can find is the middle longitudinal white line is shorter in clemensella." - Steven Whitebread (pers. comm., 4/1/2020).
