This male Migrant Hawker posed nicely by the track by Trev's Quarry at St Aldhelms. A few years ago, I was struggling to understand why I was regularly seeing Migrant Hawkers at Trev's Quarry, given there appeared to be no water source nearby to the quarry. Then a conversation with one of the quarrymen who works there confirmed they breed in a couple of small water tanks in the quarry: mystery solved.
