Grass-veneer moths, Crambidae species, are "rolled-up" moths with long snouts that, although night-flying, are easily disturbed from their grass habitat during the day. The Grass-veneer Crambus lathoniellus is a common example. Its UK flight time is mainly May-Aug. Its wingspan, rarely seen, is 18-22mm. More useful for a rolled-up "Crambid" is its length 11-14mm.

It has white streaks with tan lines and borders, the main white streak being a thin triangle or lozenge shape. It has an open curve or angled "less than" symbol at the rear in white bordered by brown. There is a small triangle behind it and dark spots before the silver-fringed metallic edging. (Crambus pascuella, silvella and some others are a little similar.) If visible, the hind wing is mid to dark brown rather than pale as in C. pascuella.

Crambus lathoniellus Grass-veneer The angled white streak suggests this is a lathoniellus at night.
