Leucophenga varia

(Walker, 1849)

Leucophenga varia is a fruit fly in the Drosophilidae. Unlike most members of its family, which typically feed on decaying fruit and yeasts, this species has been documented feeding on mushrooms. This unusual dietary specialization has driven distinct evolutionary changes in its innate immune system, particularly affecting the Diptericin gene. The species occurs in North America and has also been recorded in Brazil.

Diet

Feeds on mushrooms. This dietary specialization distinguishes it from most other Drosophilidae.

Similar Taxa

  • Other DrosophilidaeMost other members of the feed on decaying fruit and yeasts rather than mushrooms, and lack the associated evolutionary modifications to the Diptericin gene.

Immune system evolution

The ' mushroom-feeding habit has impacted the evolution of the Diptericin gene in its innate immune system, representing a documented case of diet-driven molecular evolution.
