Agrilus pulchellus
Beautiful Fleabane Root-borer
Agrilus pulchellus is a species of metallic wood-boring beetle in the family Buprestidae. It is found in Central America and North America, with records from the southwestern United States and Mexico. The species is associated with fleabane (Erigeron) as a host plant, as indicated by its common name. Like other Agrilus species, it is a wood-borer whose larvae develop in plant roots or stems.
Neolasioptera erigerontis
Neolasioptera erigerontis is a gall midge in the family Cecidomyiidae, first described by Ephraim Porter Felt in 1907. The specific epithet "erigerontis" indicates an association with plants in the genus Erigeron (fleabanes). Like other members of its genus, this species is presumed to induce galls on its host plants. The species is documented in North American collections and has been recorded in citizen science observations.
Rhopalomyia erigerontis
Rhopalomyia erigerontis is a gall midge in the family Cecidomyiidae. It is known to induce galls on Erigeron (fleabane) species. The species was described by Felt in 1916. Like other members of its genus, it is associated with Asteraceae host plants.
Schinia obscurata
Obscure Schinia Moth, Erigeron Flower Moth
Schinia obscurata is a noctuid moth in the subfamily Heliothinae, commonly known as the obscure schinia moth or Erigeron flower moth. It is one of approximately 123 North American species in the genus Schinia, a group noted for often colorful adults that frequently rest on or near their host plant flowers. The species is distributed across central and eastern North America, with larvae that specialize on Erigeron species.
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.
