Hepialidae, known as Swift Moths or Ghost Moths, is a primitive group of moths, and there are around 500 species worldwide, and just 5 species in the UK. They have elongated wings which when at rest they hold almost vertically against their bodies. The adults have no functional probosis, so are unable to feed. They also have very short antennae. The caterpillars live under ground feed on the roots of plants, and remain so for up to two years where they will eventually pupate.
Both these featured species are often attracted to light and can be seen in various habitats including parks and gardens, often during early dusk. Both are common and widespread.
