Editing Peppered moth (section)

== Description ==
The wingspan ranges from 45&nbsp;mm to 62&nbsp;mm (median 55&nbsp;mm). It is relatively stout-bodied, with forewings relatively narrow-elongate. The wings are white, "peppered" with black, and with more-or-less distinct cross lines, also black. These transverse wing lines and "peppered" maculation (spotting) can also, in rare instances, be gray or brown; the spotting pattern, in particularly very rare cases, is sometimes a combination of brown and black/gray.<ref>{{Cite web|title=Photos of Peppered Moth (Biston betularia) · iNaturalist|url=https://www.inaturalist.org/taxa/143517-Biston-betularia/browse_photos|access-date=2020-11-16|website=iNaturalist|language=en}}</ref> The black speckling varies in amount, in some examples it is almost absent, whilst in others it is so dense that the wings appear to be black sprinkled with white. The antennae of males are strongly bipectinate.<ref>Richard South, 1909 ''The Moths of the British Isles'' Frederick Warne</ref><ref>Watson, L., and Dallwitz, M.J. 2003 onwards.
