Alucita semophantis is a species of moth in the family Alucitidae, commonly known as many‑plumed moths. It was first described by Edward Meyrick in 1924. The species is endemic to Australia, where it has been recorded from several states, including Queensland and New South Wales.

Description
Alucita semophantis typifies the distinctive morphology of many‑plumed moths. Adults have a wingspan of approximately 12–15 mm. The forewings and hindwings are divided into six narrow, feather‑like plumes per wing, giving a delicate, comb‑like appearance. The ground colour of the wings is a muted brownish‑grey with subtle silver‑white streaks and a faint darker central band. Antennae are filiform and relatively short, and the body is slender with a smooth, scaled thorax.
Distribution and Habitat
- Geographic range: Endemic to Australia; confirmed records from Queensland (particularly the coastal rain‑forest regions) and New South Wales.
- Habitat: Prefers subtropical and temperate forest habitats, especially areas with abundant host plants for larvae. The species is typically found at low to mid elevations (0–800 m).
Biology and Ecology
- Life cycle: Like other alucitid moths, A. semophantis undergoes complete metamorphosis (egg → larva → pupa → adult).
- Larval host plants: The larvae are thought to feed on the flowers and developing seeds of various members of the family Convolvulaceae, though specific host records for A. semophantis remain limited.
- Behavior: Adults are nocturnal and attracted to light. They are often observed hovering near their host plants during dusk, where they mate and oviposit.
Conservation Status
The species has not been evaluated by the International Union for Conservation of Nature (IUCN). Its relatively localized distribution and lack of major threats suggest it is not currently at high risk, but habitat loss due to deforestation could impact local populations.
