Unless indicated otherwise, the following attributes are implicit throughout the descriptions, except where the characters concerned are inapplicable.
Adults. Adults not minute.
The fringes of the wings shorter than the maximum width of the hind-wings.
Larvae. The larval case not of sand grains and shield-shaped with wing-like extensions; not made of sand grains and curved, the hind extremity not covered by a dark membrane with a central slit; not particularly small, not seed- or flask-shaped; not constructed of vegetable matter arranged spirally.
We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
