Aquatic ecologist specialising in fish. Also very interested in moths, including leaf-mining larvae.
Now is a good time of year to look for Pale Tussock larvae. Handily, they fluoresce under UV. Here's one on the apple tree in my garden.

Nice to see a few moths at last! Acleris literana (2nd garden record), Phyllonorycter oxyacanthae (probably, will check it isn't the much rarer P. mespilella) and P. blancardella (probably, but will check in case P. hostis is lurking in the county).
