Morley’s Final Catalogue: Another Angelica-feeder. Taken at both Southwold and Homersfield in 1897 (Ctw).
Recent Status: A rare species in Suffolk.
Life Style: Single brooded, night flying and hibernates. Comes to light. The larvae feed from a rolled leaflet on Apiaceae species, leaves, flowers or seeds. Pupates in a cocoon on the ground
Identification: This species is similar to A. heracliana and A. cnicella. A. cnicella is confined to the sea shore. A. ciliella adult live moths can be reliably separated from A. heracliana on colour. A. ciliella has a pink or slightly purplish pink tinge. At a minimum this is on the underside of the hindwing cilia then on the hind leg hairs. This colour can extent over the whole moth. A. heracliana never has this colour. The number of lines in the hindwing cilia is not a reliable character as A. heracliana can also have 5 but they are less strong. A. ciliella is larger than A. heracliana and the markings are more strongly contrasting. More Info Genitalia differences should only be used with a good prep and top quality microscope. The process on the valves in the male must be seen to be twisted in A. ciliella. The sigmoid shape can also be seen in A. ciliella but not as strongly as in A. heracliana. The difference in the female is in the pre and post ostium lamellae shape and not the signum which is variable. More Info
