Early stages still out there

On Saturday I found the early stages of a few micros on the A34 embankment just north of Wolvercote.  There are still a few leaves remaining on some trees, enough to record the leaf mine of Stigmella salicis from sallow, although nothing was present on the more numerous osier.  The teasel heads proved to hold the larvae of Endothenia gentianaeana and Cochylis roseana - here in Somerset the former is present in just about every teasel head, even very isolated plants, and on the brief look I have had so far it looks like the same is true around Oxford.  The larvae are easy to rear by keeping the teasel-heads somewhere cool until the spring, and can be found throughout the winter.
