'Glossary' opens an
family containing the narrow-winged Crambinae 'grass-moths' such
as the Crambus and Agriphila spp. as well as
broad-winged species such as Pyraustinae which includes the
colourful Pyrausta spp..
The Crambidae have a
structure in the 'ears'
called the praecinctorium, which joins two tympanic
membranes. This is absent from the Pyralidae.
