Identification

Adult Markings: Species in this genus overlap one another in the coloration and pattern of the forewings and in many cases dissection is required to identify them to species (Heinrich 1926). However, strongly marked specimens show characteristic differences which Heinrich used to create a key based on appearance alone. Bactra verutana and furfurana -- the two species that occur in our area -- are both clay colored to dark wood-brown (Forbes, 1923). According to Heinrich, they differ mainly in terms of the markings (or lack thereof) along the costal region of the wing. In furfurana, a dark basal patch is present that reaches outward to the costa, or is at least represented by an outer dark margin on the costal half of the wing. In verutana, the costal region lacks any dark patches, particularly any extension of a basal dark patch out to the costa. The basal area is typically dark and sharply bent in at the cell (Forbes, 1923).
Adult ID Requirements: Identifiable from photos showing hindwings, abdomen, or other specialized views [e.g., frons, palps, antennae, undersides].
