Both sexes with complete, banded wings; median pale band shorter than distal dark band. Body and legs brown, antennal segment III brown, with basal third brownish yellow. Antennae 9-segmented, segment III long with linear sensorium about 0.3 as long as segment, IV with sensorium almost 0.5 as long as segment and curved distally; segments V–IX forming a single unit with V slightly shorter than VI–IX. Head and pronotum with no long setae. Fore tarsus apically with stout recurved ventral hamus. Marginal setae on sternites arising at or close to margin; sternite VII with two pairs of accessory setae arising well in front of margin.
Male tergites IV and V sometimes with very small paired dorsal tubercles; setae at base of bifurcate claspers on tergite IX almost as long as clasper, with no stout curved seta lateral to clasper.
A. duvali is a member of the A. fasciatus group but has antennal segment III more extensively brown, and the seta at the base of the claspers in males is shorter. About 105 species are placed currently in the genus Aeolothrips. Most of these are from the Palaearctic Region (including the Mediterranean, Iran and northern India, but with five species extending through eastern Africa to South Africa), with about 30 species from the Nearctic (mainly western USA). Only one species of this genus is known from the Neotropics, A. fasciatipennis described from Chile, but Mound & Marullo (1996) indicate this is probably the same as A. fasciatus.
Swept from a range of wild plants, particularly flowers of Mimulus aurantiacus [Scrophulariaceae], but with no information on any specificity for breeding. Presumably a facultative predator in flowers, with a mixed diet of pollen and the larvae of other thrips.
Described from Texas, this species is recorded from California, Arizona, Nevada, New Mexico, Colorado, Utah, Arkansas, Wyoming, Oklahoma and Mexico.
