Alucita

Wings divided into six (rarely fewer) feather-like plumes with deeply cleft margins, creating a fringed appearance unlike typical scaled Lepidoptera wings. Wing pattern often includes white, brown, and black chevron markings. Small size: wingspans typically 10–20 mm. Antennae filiform. At rest, wings are often held in a tent-like or slightly spread posture, displaying the plumed structure.

Habitats vary by species but frequently include gardens, woodlands, and shrublands where host plants in Caprifoliaceae occur. Specific associations include areas with Lonicera (honeysuckle) and Symphoricarpos (snowberry).

Genus occurs almost worldwide. Representative distributions: Alucita hexadactyla widespread across UK and Ireland; Alucita montana from southwestern Quebec and Vermont west to British Columbia, south to Arizona, California, and Texas; Alucita adriendenisi from northwestern Quebec and New York to Alberta and Northwest Territories, with isolated southern populations in West Virginia, Arizona, and Texas; Alucita lalannei in Ontario, Manitoba, and Alberta, Canada.

Adult activity varies by species and latitude. Alucita hexadactyla flies throughout the year in the UK, with peak activity in warmer months. North American species active during summer months.

Larvae feed on buds, flowers, and leaves of Caprifoliaceae. Documented host plants include Lonicera caprifolium, L. periclymenum, L. xylosteum, L. dioica, and Symphoricarpos spp. Adult feeding habits not documented.

• Lonicera caprifolium - larval hostbuds, flowers, and leaves
• Lonicera periclymenum - larval hostbuds, flowers, and leaves
• Lonicera xylosteum - larval hostbuds, flowers, and leaves
• Lonicera dioica - larval hostflowers; confirmed in Michigan
• Symphoricarpos spp. - larval hostassociated with caterpillars

Complete metamorphosis with egg, larva, pupa, and adult stages. Larvae feed on host plant reproductive and vegetative tissues. Pupation site not explicitly documented in available sources.

Adults attracted to light, frequently observed at windows and artificial lights around buildings. Wing structure with multiple feather-like plumes may function in reducing detectability to bat echolocation by decreasing the intensity of ultrasonic echo returns.

Larvae act as herbivores on Caprifoliaceae, potentially influencing flower and fruit production of host plants. Role in food webs as prey for insectivores including bats.

Alucita hexadactyla genome sequenced as first chromosomally complete assembly for family Alucitidae and superfamily Alucitoidea (878.53 Mb, 30 chromosomal pseudomolecules). Some species of minor interest to lepidopterists due to distinctive morphology. Not known as agricultural pests.

• Pterophoridae (plume moths)Also have divided wings, but typically with 2–3 plumes per wing rather than 6; historically confused with Alucitidae but now placed in separate superfamily
• CopromorphoideaFormerly included species now placed in Alucita; distinguished by wing venation and genitalia characters
