MYOSOTON. Water Chickweed. [Caryophyllaceae]

Water Chickweed (M. aquaticum) is the only species of Myosoton recorded in Britain. It is a native species. Two dipterous miners, the anthomyiid Pegomya flavifrons and the drosophilid Scaptomyza graminum, are recorded on Myosoton in Britain. Elsewhere the agromyzid Amauromyza flavifrons, the anthomyiid Pegomya flavifrons and the drosophilid Scaptomyza graminum are recorded mining Myosoton. One non-dipterous miner is recorded on Myosoton in Britain (see below).

Key for the identification of the known Diptera mines in Britain.

1> Upper side blotch mine beginning with a deeper, almost full depth corridor. Frass grains not in thread-like pieces, irregularly scattered. In the large, later blotch indistinct primary and secondary frass lines are found; the frass accumulated in the middle. Mine of Pegomya flavifrons on Silene dioica.
