Elytrigia repens, ‘t Twiske
front and rear spiraculum, lateral (the black spot in the centre is the “wart”
rear spiracula dorsal, with, laterally, the “warts”; the right picture shows a magnification of one of the papillae
cephalic skeleton and mandibles
Nowakowski (1973a), Darvas & Papp (1985a) and Dempewolf (2001a) give details about the larva. The black “warts” at either side of the rear spiracula are relatively small, and don’t have a root that projects into the interior, unlike in C. pygmaea.
The description by de Meijere (1928a) refers to a quite different species!
