Procecidochares flavipes
Procecidochares flavipes is a species of tephritid fruit fly in the genus Procecidochares, family Tephritidae. It was described by Aldrich in 1929. The species belongs to a genus known for gall-inducing behavior on plants, though specific details for this species are limited. It occurs in North America, with records from the United States and Mexico.
Procecidochares minuta
Procecidochares minuta is a species of tephritid fruit fly described by Snow in 1894. It belongs to the genus Procecidochares, a group of gall-inducing flies within the family Tephritidae. The species is known from North America, specifically the United States. Like other members of its genus, it likely induces galls on host plants, though specific details for this species remain poorly documented.
Terellia ruficauda
Red-tailed Thistle Fly
Terellia ruficauda is a tephritid gall fly native to the Palearctic region, now introduced to North America. The species is notable for its larval association with Cirsium arvense (creeping thistle), where larvae develop within the flower heads. Adults are recognized by the distinctive reddish coloration of the abdomen referenced in the specific epithet.
Trupanea wheeleri
Trupanea wheeleri is a species of fruit fly in the family Tephritidae, first described by Curran in 1932. It belongs to the genus Trupanea, a group of tephritid flies commonly known as gall flies or picture-winged flies. The species is known from North America, specifically recorded from Canada and the United States. Like other members of its genus, it likely develops in plant galls, though specific host associations remain undocumented in the available literature.
Urophora
thistle gall flies, gall flies
Urophora is a genus of tephritid flies distributed across the Palaearctic Region, with species exhibiting close associations with Asteraceae plants. Larvae of many species induce galls on stems or other plant parts of thistles and related plants. The genus includes at least 13 species in Karaman Province, Türkiye alone, with new species continuing to be documented. Urophora cardui, a well-studied species, forms multi-chambered stem galls on Cirsium spp. and serves as host for multiple parasitoid wasps.
Valentibulla californica
Elliptical Stem Gall Fly
Valentibulla californica is a species of fruit fly in the family Tephritidae, commonly known as the Elliptical Stem Gall Fly. The species was described by Coquillett in 1894. Like other members of the genus Valentibulla, it is associated with gall formation on plant stems. The species is found in the United States, particularly in California as suggested by its specific epithet.
