Let me start with a simple photo of Paracercion v-nigrum. Until now the males observed just inside Cao Bang Province along the TL 212 had missed the "V" mark on S8, although everything else pointed to that species. Rice fields had been harvested and were dry, but in the small pool next to fields in which we had observed them before one male, with all blue S8-9, was present. But earlier in the day, inside Pia Oac Nature Reserve, in a small pond with some emergent grasses, I took photos of another and typical male.
