Asphondylia rudbeckiaeconspicua
Asphondylia rudbeckiaeconspicua is a gall midge species in the family Cecidomyiidae, first described by Carl Robert Osten-Sacken in 1878. The larvae induce galls in the flower heads of cutleaf coneflower (Rudbeckia laciniata), developing within distinct zones of the capitulum tissue. This species serves as host to a diverse guild of parasitoid wasps that exhibit stratified distribution patterns within the gall structure, with different parasitoid species occupying different depth zones.
Isophrictis rudbeckiella
Isophrictis rudbeckiella is a gelechiid moth described by Bottimer in 1926. It is recorded from the south-central and midwestern United States, with a wingspan of 11.5–16 mm. The species is associated with Rudbeckia maxima, on which its larvae develop within flowerheads.
Stelis rudbeckiarum
Coneflower Painted-Dark bee
Stelis rudbeckiarum is a species of cuckoo bee in the family Megachilidae, described by Cockerell in 1904. As a member of the genus Stelis, it is an obligate cleptoparasite that lays its eggs in the nests of other bees. The species is distributed across North America and Central America. Its specific epithet 'rudbeckiarum' suggests an association with Rudbeckia (coneflowers), likely reflecting host or foraging relationships.
Strauzia intermedia
Strauzia intermedia is a species of tephritid fruit fly in the family Tephritidae. The species was originally described as Trypeta intermedia by Loew in 1873. It has been documented developing in Rudbeckia laciniata (cutleaf coneflower), indicating a specialized host relationship with this plant. As a member of the genus Strauzia, it belongs to a group of fruit flies commonly associated with Asteraceae host plants.
