Epitrimerus malimarginemtorquens

The mite Epitrimerus malimarginemtorquens causes a leaf roll gall on the leaves of Apple.  The leaf roll is narrow and hard, approx. 1 mm broad with white hairs alongside the roll on the upper surface (BPGS handbook).

Other species cause narrow leaf-rolls - see Dasineura mali (a gall-midge).  This does not have the hairs along the roll.

Please provide photograph and state host species.

The galls may be found wherever the host Apple trees occur.

Galls can be seen when the host species are in leaf.

Status in Britain is difficult to determine due to lack of records.
