Luffia ferchaultella §1 female (deceased)
ID: Winged males are known to occur in Cornwall. Elsewhere in Britain only the parthenogenetic female occurs. The larval case is rounded in cross-section and 5-7mm in length and covered with green and/or black lichens and minerals. Pupation, emergence and egg-laying all occur within the larval case.
Female genitalia
The ovipositor could not be any longer - before extension the anterior ends of the posterior apophyses were located in the head. Note that S10 also has a paired linear sclerotisation, fused at its anterior end, somewhat resembling an additional pair of apohyses - presumably these provide some extra rigidity to aid oviposition.
