Atomopteryx solanalis (Barnes & McDunnough, 1913)

Alternative combinations: none
Classification: Pyraloidea: Crambidae: Spilomelinae, Leucinodes group
Adult recognition
Forewing length: 7.5–9.0 mm, narrow. The wing pattern is solidly pale brown, without contrasting areas of white or dark brown. The faint, blackish PM line undulates across the wing with a shallow concavity on the medial veins. In the hind wing venationVenation:

Similar species
Atomopteryx pterophoralis is widely distributed in the Caribbean, Central and South America. The plain brown wing pattern is similar to A. solanalis, but male A. pterophoralis lack a fibulum. In Puerto Rico, it has been reared from Solanum torvum leaves (Medina Gaud and Martorell 1970Medina Gaud and Martorell 1970:
Medina Gaud S and Martorell LF. 1970. New insect records for Puerto Rico. Journal of Agriculture of the University of Puerto Rico 57: 247-254.).
Behavior
A leaf-tier. Collected together with Lineodes integra.
Distribution
USA: Florida. Rare; most common in the Florida Keys. Also in the Bahamas and Cuba.
Hosts
“Solanum verbascifolium” (USNM)
Solanum sp. (original description)
Comments
This species was described from southern Florida. It was synonymized by Dyar (1913) with A. pterophoralis but considered to be a good species by Munroe (Kimball 1965Kimball 1965:
Kimball CP. 1965. The Lepidoptera of Florida: an annotated checklist. Arthropods of Florida and Neighboring Land Areas, Vol. 1. Division of Plant Industry, State of Florida Department of Agriculture, Gainesville, Florida. V+363 pp., 26 plates.). Specimens identical to A. solanalis also have been collected in Cuba, along with other species that differ as indicated under Similar Species.
