Morley's Final Catalogue : Proved, by Waller's breeding along with typical L. pallens from eggs of a single female, to be a colour-form of the latter species; though other broods, reared by him, bred true to parents. Also "I have taken nearly fifty specimens, of red and yellow and other forms. South exhibited the mixed brood before the S. Lond. Ent. Soc. Generally flavicolor is considered a salt-marsh forrn of L. pallens "(Wlr, in lit. 1935 ; cf. Ent. Rec. 1907, p. 290). One at sugar in Waldringfield garden in July 1929 (Wiltshire).
