Two for the price of one this week. The plant is Himalayan honeysuckle (Leycesteria formosa), not a British native as you can guess from its name, but a plant that’s now naturalised quite extensively in the wild, at least in my local area. The leafmines were found on 18 December, quite late in the year but a sign of how mild our weather has been so far this winter.

These first mines were made by the larvae of the tiny fly Chromatomyia lonicerae. I like the description of this mine on the Nature Spot website: ‘The leafmine starts with an irregular star-like blotch with a later linear section’. You can see that in my photo on the left below, and, in the photo on the right, you can see a pupa, which remains in the mine until it emerges as an adult fly.

This second mine is the creation of the larva of the moth Phyllonorycter emberizaepenella, a beautiful little brown-and-white creature that you can see on the UK Moths website. The larva spins itself a blotch mine, which pulls the underside of the leaf together, as you can see in the photos below: top of the leaf on the left, bottom on the right.
