Abstract Floral volatiles of two introduced Oenothera species, Oe. glazioviana (= Oe. erythrosepala) and Oe. biennis, were chemically examined using the headspace method. As a result, linalool, one of the monoterpenes, was found to be the main constitutent of floral volatiles, with several other undetermined substances. Visual signals of these two Oenothera species were the same, with a strong UV-absorbent spot in the center of the corollas. Large nocturnal hawkmoth species such as Theretra japonica, Agrius convolvuli, and Deilephila elphenor lewisil are major pollinators for these two Oenothera species. An interplay between floral UV-absorbancy patterns as visual signals and floral volatiles released seems to be playing a significant role in pollinator attraction. Nectar utilization and the breeding system of Oe. glazioviana were also examined.
