Described from three females taken at Sonora Pass, California, this species has not been studied by the present authors. The fore wing is illustrated (Bailey, 1951: 75) as having one complete transverse dark band sub-basally, and a second incomplete transverse band sub-apically.
The forewing pattern of A. montanus is apparently similar to that of A. interruptus Bailey, described on two females from Utah. Just over 90 species are placed currently in the genus Aeolothrips, of which more than 50 are from the Palaearctic Region (mainly Europe), and 28 from the Nearctic (mainly western USA). Only two species are recorded from the Neotropics; the one from Chile is probably the same as A. fasciatus, and one from Panama is probably not a member of this genus (Mound & Marullo, 1996).

Possibly flower living and predatory on other small arthropods.
