Four hours of staring at the sea, hopefully motivating a student who had seen none of her target study species for a month, produced a very short list of the two daily present terns (Sandwich and Royal) and one pomarine skua.  I distracted myself for a while by photographing sheep, then noticed a familiar looking butterfly feeding on the cliff top.

It is painted lady, a species found throughout Europe. I had no idea, as quick Google Scholar search revealed,  that this species migrates between  Europe and West Africa, though in a rather different manner from birds. Migration is staged over several months and several generations. The species breeds throughout the year,  adults flying south from Europe in summer , breeding and dying and the next generation continuing the southwards migration.
