Uroleucon erigeronense
Large fleabane daisy aphid
Uroleucon erigeronense is a species of aphid in the family Aphididae, first described by Thomas in 1878. It feeds primarily on plants in the Asteraceae family, with a particular association with Erigeron (fleabane) species. The species exhibits flexible reproductive strategies: holocyclic in northern climates, producing sexual forms in autumn, and anholocyclic in warmer regions. It shows seasonal host-shifting behavior, moving between overwintering perennial hosts and blooming annuals. Native to North America, it has been introduced to Europe, Australia, and Korea.
Uroleucon eupatoricolens
Uroleucon eupatoricolens is an aphid species in the family Aphididae. Like other members of the genus Uroleucon, it is a sap-sucking insect that feeds on plants in the Asteraceae family. The species reproduces parthenogenetically during spring and summer, producing all-female colonies. When disturbed, colonies exhibit synchronized twitching and kicking defensive behaviors. These aphids serve as important prey for diverse predator communities including lady beetles, lacewings, flower flies, and spiders.
Uroleucon verbesinae
Bicolored Frostweed Aphid
Uroleucon verbesinae is a North American aphid species in the family Aphididae. It belongs to the large genus Uroleucon, whose members typically feed on plants in the Asteraceae family. The species reproduces parthenogenetically during spring and summer, producing all-female colonies. Like other Uroleucon aphids, it exhibits synchronized defensive behaviors when disturbed.
