mine

Spencer’s (1963b) description of the mine is rather succinct: “beginning with a narrow channel, then developing into a distinctive blotch, filled centrally with blackish frass; the mine does not occupy the entire leaf.” In the figure he adds the initial corridor follows the leaf margin. Neither larva nor puparium are described.

Robbins (1991a), without mentioning a source, adds that the mine resembles the one pf A. pseudorufipes Nowakowski 1964, and that pupation is outside the mine. A. pseudorufipes is a miner of Myosotis, and in describing that species (Nowakowski, 1964a) some comparisions are made with A. abiens.
