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 nigrotuberculatum
red goldenrod aphid
Uroleucon nigrotuberculatum, commonly known as the red goldenrod aphid, is a North American aphid species introduced to Japan. In its native range, it is a specialist feeder on Solidago (goldenrod) species. Following introduction to Japan, this aphid has demonstrated remarkable dietary flexibility, expanding its host range to include multiple exotic plant species beyond its native specialization. The species exhibits complex ecological interactions, including semiochemical-mediated relationships with gall-forming flies and serves as prey for various native parasitoids and predators in its introduced range.
Uroleucon taraxaci
Bronze-brown Dandelion Aphid
Uroleucon taraxaci is a species of aphid in the family Aphididae, commonly known as the Bronze-brown Dandelion Aphid. As a member of the genus Uroleucon, it shares characteristics with related species that exhibit parthenogenetic reproduction during spring and summer, forming all-female colonies. The species is associated with plants in the Asteraceae family, particularly dandelion (Taraxacum). Like other Uroleucon aphids, it produces honeydew that attracts predators and parasitoids. The species has been documented across parts of Europe and Asia.
