Royal mint

There's a substantial margin of flowering water mint (Mentha aquatica) along the Mon and Brecon canal at South Sebastopol at the moment that's attracting a good variety of invertebrate interest. Common hoverflies along with other assorted diptera are augmented by a few butterflies. This clouded yellow was found along with a small copper and green veined white. Diptera of note included this Tachina fera.
