CORNUS. Dogwoods and Dwarf Cornel. [Cornaceae]

Two native species of Cornus are recorded in Britain - Dwarf Cornel (C. suecica) and Dogwood (C. sanguinea). Eight other species have been introduced, including Cornelian-cherry (C. mas), White Dogwood (C. alba), Red-osier Dogwood (C. sericea) and Creeping Dogwood (C. canadensis). Only one dipterous miner, the agromyzid Phytomyza agromyzina, is recorded on Cornus in Britain and elsewhere. Two non-dipterous miners, Antispila metallella and Antispila treitschkiella, are recorded on Cornus in Britain (see below). Elsewhere three additional British non-dipterous miners are recorded on Cornus (see below).

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