Calybites phasianipennella

The larva of the moth Calybites phasianipennella mines the leaves of various plants including Dock species, Yellow Loosestrife,Water-pepper, Black Bindweed and Redshank. An initial gallery leads to a blotch; later instars leaves the mine and feeds inside a cone-shaped leaf-roll, made by cutting a strip out of the leaf the leaf alongside the midrib.

Wachtliella persicariae

The larva of the gall midge Wachtliella persicariae causes galls to form on various plants of the Polygonaceae family including Amphibious Bistort and Redshank. The gall takes the form of marginal rolls, usually on both sides of the leaf which become markedly thickened and often spirally or otherwise contorted. Often several leaves at the shoot tip are affected.
