Amauromyza morionella

The larva of the Agromyzid fly Amauromyza morionella mines the leaves of various Stachys and Lamium species. The frass is conspicuous in the mine and the mine is initially linear, then develops into a white blotch, often enveloping the early mine.

Amauromyza (Cephalomyza) labiatarum

The larva of the Agromyzif fly Amauromyza labiatarum mines the leaves of various plants including Dead-nettles and Woundworts, producing a mine with a narrow gallery leading to a largish blotch on the upper surface. Frass is green and indistinct in the gallery - small grains may be seen at the gallery edge.
