Lepidoptera / Alucitidae

Alucita hexadactyla spreads four wings divided into six feather-like fronds apiece. This small honeysuckle-associated moth carries brown, black and white chevrons across an unusually open wing structure.

Identity and classification

Alucita hexadactyla Linnaeus, 1758 belongs to Alucitidae. It is the only member of this family recorded in Britain. [1][2]

Morphology and identification

The 14–16 mm wingspan contains four wings divided into six fronds each. White, brown and black chevrons continue across the narrow, feather-edged divisions. [1]

Distribution and habitat

The moth is widespread in Britain and Ireland and occupies gardens and woodland with honeysuckle. [1]

Life cycle

Adults may be found in Britain at almost any season, rather than within a single short summer flight period. [2]

Feeding and host plants

Honeysuckles, Lonicera, supply the larvae’s buds, flowers and leaves. The genomic account names Lonicera caprifolium, L. periclymenum and L. xylosteum among the associated species. [1][3]

Behaviour

The adults are nocturnal and attracted to light. A mating pair photographed on a lit kitchen window was documented by De Vlinderstichting in April 2012. [2][3]

Distinctive biology

The male genome assembly spans 878.53 megabases. Approximately 99.74% of that sequence was assigned to 30 chromosome-scale pseudomolecules, including the Z chromosome. [1]

Nomenclature and history

The epithet hexadactyla means “six-fingered”, referring to each wing’s six divisions. The English name “twenty-plume” understates the complete complement of 24 fronds. [1][2]

Display and care

Keep the enclosure closed and display it in indirect light, away from heat and damp conditions. Handle the frame by its edges and clean only its exterior according to the maker’s instructions.
