Asphondylia atriplicicola

(Cockerell, 1898)

Saltbush Blister Gall Midge

Asphondylia atriplicicola is a gall midge in the Cecidomyiidae that induces blister galls on saltbush (Atriplex ). Like other members of the Asphondylia, this species manipulates plant tissue to form protective galls within which its larvae develop. The specific epithet 'atriplicicola' directly references its association with Atriplex, the saltbush genus. The genus Asphondylia is notable for inducing galls on diverse host plants, with different species specializing on particular plant including holly, creosote, and saltbush.

Identification

Identified by the distinctive blister galls induced on Atriplex (saltbush) . are small, mosquito-like flies typical of Cecidomyiidae. Larvae are tiny yellow maggots found within galls. Distinguished from congeneric species by plant association: A. ilicicola occurs on holly (Ilex), A. auripila group species on creosote (Larrea), while A. atriplicicola is specific to saltbush (Atriplex).

Habitat

Associated with saltbush (Atriplex) vegetation in arid and semi-arid environments where plants occur.

Distribution

Native to North America; distribution corresponds to range of Atriplex in western and southwestern United States and Mexico.

Diet

Larvae feed on plant tissue within induced galls on Atriplex .

Host Associations

  • Atriplex - obligateInduces blister galls on saltbush ; larval development occurs within galls

Life Cycle

emerge from pupal cases to mate. Females deposit into developing plant tissue, inducing gall formation. Larvae feed within galls, consuming plant tissue. Development slows during winter; occurs in spring, with adults emerging to complete the cycle.

Behavior

Females manipulate plant through secretions to induce gall formation, creating protective chambers and food sources for offspring.

Ecological Role

Gall inducer that modifies plant growth patterns. Provides microhabitat for potential and .
