common swift

<em>Korscheltellus lupulina</em>, the common swift moth or ghost swift, is a moth in the family Hepialidae, order Lepidoptera. It is recorded from Belgium, Denmark, Norway, and Sweden, with a broader distribution across Europe and temperate Asia. The species typically inhabits grasslands, meadows, garden lawns, and field margins where its larval host plants grow. Adult ghost swifts are notable for their spectacular lek-like swarming behavior at dusk, in which males hover in groups to attract females, appearing to hover like ghosts over vegetation. Larvae of <em>Korscheltellus lupulina</em> feed underground on the roots of a variety of herbaceous plants and grasses, including hop (Humulus lupulus), which gives the species its specific name. Adults do not feed, having vestigial mouthparts, and live only long enough to reproduce. Biological traits including precise larval duration, adult size measurements, and detailed host plant specificity remain poorly documented at the species level. The species is assessed as Least Concern by the IUCN, with stable populations across its European range and no significant conservation threats identified.
