Asphondylia bigeloviaebrassicoides

(Townsend, 1893)

Asphondylia bigeloviaebrassicoides is a of gall midge in the Cecidomyiidae, first described by Townsend in 1893. Like other members of the Asphondylia, this species induces galls on plant tissue. The specific epithet suggests an association with plants in the genus Bigelowia and potentially Brassicaceae , though detailed host records remain limited. Gall midges in this genus are known for their highly specialized relationships with host plants and their ability to manipulate plant development to create protected feeding structures.

Identification

This can be identified by the galls it produces on its plants. Asphondylia are small, delicate flies with long bearing bead-like segments (flagellomeres) characteristic of Cecidomyiidae. The specific gall on Bigelowia and related hosts would distinguish this species from other Asphondylia, though precise diagnostic features require examination.

Distribution

Records indicate this occurs in North America, with the original description based on specimens from the southwestern United States. The Asphondylia has broad distribution across temperate and tropical regions, with many species showing regional tied to their plant ranges.

Diet

Larvae feed internally within plant galls, consuming gall tissue that the insect itself has induced the plant to produce. This specialized feeding strategy provides both nutrition and protection from and environmental conditions.

Host Associations

Bigelowia - gall induction of composite plants in the Asteraceae ; the specific epithet suggests this as primary

Life Cycle

females deposit into actively growing plant tissue. Larvae hatch and induce gall formation through chemical secretions that manipulate plant and . Larvae develop within the gall, feeding on the proliferating plant tissue. occurs within or adjacent to the gall. Adults emerge to mate and continue the cycle, with timing synchronized to plant .

Behavior

Females exhibit precise selection, laying only in specific plant and often in particular tissue types. The gall induction process represents a sophisticated form of plant manipulation, with the insect redirecting plant growth to create a custom microhabitat.

Ecological Role

As a gall inducer, this contributes to plant-insect interaction diversity and creates microhabitats that may be used by other organisms. Gall midges can influence plant resource allocation and may serve as prey for and other natural enemies.
