frass pattern

mine

Narrow, remarkably long, corridor. The inital part is rather strongly branched. The mine is upper-surface, rarley partly lower-surface. Frass variable: isolated grains, reddish-brown pearl chains, sometimes also there is a central green band. Pupation mostly outside the mine; when not, there is a slit alreadly made in the epidermis in front of the puparium to serve as an exit for the fly (Hering, 1924a, 1957a). Exit slit (always?) in lower epidermis.
