Large fleabane daisy aphid

Uroleucon erigeronense is holocyclic in northern climates, producing alate males and sexual females in autumn. In warmer regions, such as the southern United States, it can reproduce anholocyclically. It inhabits a wide range of host plants within the Asteraceae family, moving seasonally from overwintering perennial hosts like Ericameria and Chrysothamnus to blooming annuals and herbs in spring and summer. This pattern resembles heteroecy, although the species does not exhibit strict obligate host alternation.
