Aceria lantanae
Lantana Flower Gallmite
Aceria lantanae is a minute, worm-like gall mite in the family Eriophyidae, used as a biological control agent against the invasive weed Lantana camara. It forms characteristic flower galls on host inflorescences. Released in South Africa in 2007, it has established patchily with variable success. Its performance is determined primarily by host-plant variety rather than climatic factors, showing significant differential susceptibility across L. camara varieties.
Antistrophus
undescribed Silphium flower gall wasp
An undescribed species of gall wasp in the genus Antistrophus that induces flower galls on Silphium species, particularly in tallgrass prairie ecosystems. The wasp manipulates plant tissue to form protective galls that house developing larvae. This species represents part of a complex of Antistrophus wasps specialized on Silphium host plants, with distinct species targeting stems versus flowers.
Asphondylia florea
Creosote Flower Gall Midge
Asphondylia helianthiflorae
Asphondylia helianthiflorae is a gall midge species in the family Cecidomyiidae, first described by Felt in 1908. Like other members of its genus, this species induces galls on host plants. The specific epithet "helianthiflorae" indicates an association with sunflower (Helianthus) flowers. The genus Asphondylia is known for inducing galls on diverse plant parts including flowers, fruits, and leaves across various host species.
Ozirhincus millefolii
A gall midge in the family Cecidomyiidae. The species name 'millefolii' indicates association with Achillea millefolium (yarrow), a common host plant for this genus. Larvae develop within flower heads, inducing galls. Adults are small, delicate flies typical of the family.
