The light brown apple moth (Epiphyas postvittana), often abbreviated to LBAM, is a leafroller moth belonging to the lepidopteran family Tortricidae. Light brown apple moth adults are variable in colour and may be confused with other leafroller moths and similar species. DNA analysis is currently required to positively identify the species that are otherwise indistinguishable on gross characteristics from other moths of similar species. Typical males have a forewing length of 6–10 mm with a light brown area at the base, which is distinguishable from a much darker, red-brown area at the tip. The latter may be absent, with the moth appearing uniformly light brown, as in the females, which have only slightly darker oblique markings distinguishing the area at the tip of the wing. Females have a forewing length of 7–13 mm.
Larvae are not easily distinguished from the larvae of other tortricid leafrollers; only DNA testing is a certain identification method. The first larval instar has a dark brown head; all other instars have a light fawn head and prothoracic plate. Overwintering larvae are darker. First instar larvae are approximately 1... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Light Brown Apple Moth is recorded against all the insects logged in Liverpool (822 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
