The past and present status of Grapholita pallifrontana in Cambridgeshire has been investigated. The species was discovered in Cambridgeshire by William Warren, most likely in 1887; the next published record was in 2021. Its sole larval foodplant, Wild Liquorice Astragalus glycyphyllos has been well-documented by botanists since 1660. We visited the 15 monads with post-1985 records and relocated plants in 11 of them, plus one new adjacent monad. We subsequently revisited these 12 monads during the season when larvae are detectable within the seedpods, and found G. pallifrontana in six of the monads, concentrated in the southeast and southwest of VC29. The botanical history of these sites suggests that Wild Liquorice has probably only been present in these locations for the last half-century, and that both foodplant and moth must therefore be quite mobile. Records from adjacent vicecounties demonstrate an overall L-shaped G. pallifrontana distribution, with the Cambridgeshire colonies at its eastern extremity, and raise the question of whether most may belong to a single meta-population.
