Explanation of Names
Plagiognathus chrysanthemi (Wolff 1804)
♂ 3.60-4.18 mm, ♀ 3.18-3.52 mm(1)
Recognized by the greenish to greenish-yellow dorsum with black, weakly bristlelike setae and antennal segment 2 mostly pale with a dark base.
Easily confused with guttatipes, but distinguished by the form of the male genitalia; distributions also nonoverlapping. Also similar in coloration to cibbetsi and polhemorum, both those species with pale setae on the dorsum. Vesica with basal portion very strongly curved and with apical spines sinuously curving. Coloration of dorsum also similar to that of ribesi, but that species with a strong black transverse marking on membrane and with a black stripe on the dorsal surface of all femora. (1)
native to, and widely distributed in, the Palaearctic, adventive in our area (NS-ON south to NY-MI in the east and MT-OR-n.CA in the west)(2)
Variety of herbaceous annuals.
