Here's another often overlooked micro, Phyllocnistis saligna. I've recorded it between Taunton and Butleigh Moor, fifteen miles north-east. I don't think there are any records outside this area (it was first found here in 1906). It's well established on willows (for example crack willow and white willow). The mines are silvery trails which can be found on the upper and undersides of leaves. Larvae also feed in the adjoining twigs which can be quite noticeable if they are a darker colour and extends the recording season after leaf fall. The Levels contain an abundance of suitable habitat - I've only tried at random places off the A361.
