Moths from the family Geometridae which fly in winter. The females are wingless (have much reduced wings) which allows them to save up their energies to produce eggs in the cold winter months. Dispersal of the species is handled by the young larvae when they emerge in spring, often by 'ballooning' - hanging from silken threads and being blown away in the wind.
