Agromyza abiens/myosotidis agg.

    Description

    The larvae of Agromyza abiens and Agromyza myosotidis produce identical mines on the leaves of their larval food plants which include Borage, Comfrey and Green Alkanet. The initial narrow gallery contains frass in a double line it then expands to form a blotch mine. Several larvae may occupy a leaf to form a large blotch. The mines cannot be reliably separated to species level and for this reason we have created this page which treats them as an aggregate. It is necessary to rear through the adult and subject it to detailed examination in order to identify it to species level. If this has not taken place you should add your records to this aggregate page.
