October 4, Pia Oac. We are standing in the gold digger stream and checking the Macromia moorei flitting up and down in surprisingly good numbers. Suddenly a large dragonfly comes near and I am able to catch it. It is a very robust insect, immediately recognizable as a Sieboldius by its small head and very long legs. It is excreting eggs, so I tip its abdomen in the water until all the eggs have been dropped. After that I put it in an envelop. Quite surprising really. Since the males caught early July I had not seen it anymore, but clearly it is still flying. Shortly after, a male shows up and perches on a rock in the stream. While I carefully make my way to it, a Grey Wagtail flies in and flushes it, but luckily it soon returns. Again I am lucky enough to catch it. It is indeed the same species as earlier in the year: Sieboldius nigricolor.
