Nematopogon swammerdamella is a moth of the family Adelidae.
The moth has long, pale shining ochreous, faintly darker strigulated forewings and long antennae. The hindwings are pale grey; cilia whitish-ochreous. Head orange, face whitish. The wingspan is 17–21 mm.[1] To certainly determine the species of the genus Nematopogon dissection and study of the genitalia is necessary.
The moth flies from late April to June. The moth is only active in the late afternoon and dusk.[2] Nematopogon schwarziellus, Nematopogon pilella, and Nematopogon metaxella are similar to this species.[3]
It is found throughout most of Europe, except the Balkan Peninsula, Greece, Iceland and Ukraine. It can commonly be found throughout the British Isles in woodland.[4] The species has also been known to live in hedgerows, moorland, heathland, and other open habitats.
The caterpillars feed on decaying plant matter and various herbaceous plants. Older caterpillars live in a bivalved case on the ground. They hibernate twice and pupate inside the case.
The name honours the Dutch scientist Jan Swammerdam.
