If there is one butterfly whose male makes a truly conspicuous effort to impress the female of the species, then it must surely be the Orange-tip (Anthocharis cardamines). Those vivid orange wing tips are hard to miss, even when the males are speeding past at a hundred miles an hour. Today, at last, I saw my first Orange-tip for 2020 – in fact, I spotted four of these handsome chaps and, after following a couple back and forth along their chosen territories, I finally managed a single photo of one as it was refuelling.
