Virbia fergusoni

Distinguished from other Virbia species by diagnostic genitalia characters illustrated in the original description. Adult habitus photographs and comparative diagnoses are provided in Zaspel (2008). Separation from similar species requires examination of genitalia or reference to the diagnostic character illustrations in the taxonomic revision.

Forewing length approximately 11 mm in males and 12 mm in females. Adult habitus and genitalia morphology distinguish this species from congeners; specific coloration and pattern details are documented in the original species description with accompanying diagnostic illustrations.

Mixed oak-pine forests of the southeastern United States.

Southeastern United States: South Carolina northward, westward through Georgia and northern Florida to Alabama.

Adults recorded on wing from mid-March to mid-July, with a single September record. Multiple generations per year are probable given the extended flight period.

Multiple generations per year inferred from adult flight records spanning March through July.

• Virbia lamaeBoth are southeastern U.S. Virbia species; V. lamae is a documented habitat specialist of bogs, whereas V. fergusoni occurs in mixed oak-pine forests.
• Virbia rindgeiDescribed in the same taxonomic revision (Zaspel 2008); both are recently described species requiring genitalia examination for reliable separation.
