Taxonomy
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Lepidoptera
- Superfamily: Adeloidea
- Family: Adelidae (fairy‑long‑horn moths)
- Genus: Nemophora
- Species: Nemophora cupriacella
The species was first described by Jacob Hübner in 1813. It is placed in the genus Nemophora, which comprises many long‑antennaed moths characteristic of the family Adelidae.
Description
- Wingspan: 11–15 mm.
- Forewings: Metallic bronze‑green to coppery coloration with fine, indistinct markings; the hindwings are narrow and gray‑brown.
- Antennae: Males possess markedly long, filamentous antennae that can exceed twice the forewing length; females have shorter but still noticeably elongated antennae.
- Sexual dimorphism: Apart from antenna length, males and females are similar in wing pattern and overall size.
Distribution and Habitat
Nemophora cupriacella occurs throughout much of Europe, from the British Isles and Scandinavia in the north to the Mediterranean region in the south, and extends eastward into parts of western Asia. It inhabits open, sunny environments such as woodland edges, meadow margins, hedgerows, and gardens where host plants are present.
Life Cycle and Ecology
- Adult flight period: Adults are nocturnal and are typically on the wing from late May through July, with peak activity in June.
- Behavior: Adults are attracted to light sources and can be encountered near illuminated windows or street lamps during their flight period.
- Reproduction: Females lay eggs on or near the host plants used by the larvae.
- Larval host plants: The larvae are seed‑feeding (granivorous) and have been recorded on the seed heads of several herbaceous plants, most commonly species of Rubus (blackberries and raspberries) and Epilobium (willowherbs).
- Larval case: Young larvae construct portable cases from plant material, a characteristic behavior of many Adelidae species. The case provides protection while the larvae feed within seed capsules.
- Pupation: Pupation takes place inside the larval case, usually attached to the host plant or within leaf litter on the ground.
Conservation Status
The species is regarded as common and widespread throughout its range and is not listed on any major threatened or endangered categories. No significant population declines have been documented.
