Barbara mappana

Barbara is a of in the Tortricidae, Olethreutinae, tribe Eucosmini. The genus was established by Heinrich in 1923. These are small moths, typically with wingspans under 20 mm, belonging to a large family of tortrix or leafroller moths. Members of this genus are found in North America, with records from the northeastern United States including Vermont. The genus is part of a diverse group of microlepidoptera whose larvae often feed internally in plant tissues.

Identification

Identification to requires examination of genitalia structures. External is cryptic and similar to other small olethreutine . Dissection and comparison with or detailed illustrations is typically necessary for accurate determination. The genus can be distinguished from closely related Eucosmini genera by combinations of wing venation patterns and genitalia characteristics, particularly in the male valvae and female sterigma.
