Brassy Long-horn

Nemophora metallica (Poda, 1761) belongs to Adelidae. Adults span approximately 15–20 mm. [1][2]

Bronze wings contrast with long antennae. Male antennae are approximately three times forewing length; female antennae are about half the length of male antennae. [2]

The male antennae are white towards their tips. [1]

The European range includes dry meadows and flower-rich open habitats. [1]

British records concentrate in southern England and East Anglia. [2]

Larvae begin in scabious seeds, then construct portable silk-and-plant cases on the ground. They overwinter as mature larvae and pupate inside the cases in spring. [1]

Field scabious, Knautia arvensis, is the sole Finnish host reported. Later larvae eat lower leaves and detritus; adults take nectar. [1]

Adults fly in sunshine. The British flight season falls principally in June and July, when the moths can be encountered around their flowering hosts. [2]

The Finnish male’s assembly spans 710.84 megabases, with most sequence assigned to 31 chromosome-scale pseudomolecules, including Z. [1]

Finland’s 2019 assessment lists the species as Endangered. [1]

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.
