About Periploca ceanothiella (Cosens, 1908)
Periploca ceanothiella, commonly known as the ceanothus stem gall moth, is a moth species belonging to the family Cosmopterigidae. It was first described by Cosens in 1908. This species is found in North America, with recorded occurrences in Arizona, California, Florida, Kansas, Indiana, Louisiana, Mississippi, New York, Ontario, Oregon, South Carolina, and Texas. It has a wingspan of 10 mm. Adult moths fly between March and August, and also in December. The larvae of this species feed on Ceanothus species. After hatching, young larvae bore into the stem of their host plant; their feeding activity triggers the formation of stem galls. The species spends the winter in the larval stage inside the gall, and pupation occurs in summer.
