Agromyza idaeiana

    Description

    The larvae of the fly Agromyza idaeiana usually mine the leaves of Creeping Cinquefoil (Potentilla reptans) although Occasionally other Potentilla species may be used. It creates a full depth mine without a definite shape and little frass. Some silk is deposited in the mine. The larvae soon leave the mine and continue feeding among spun leaves.
