There are 4 Neurothemis species that have been recorded in Vietnam according to the synopsis by Do Manh Cuong. There is N. fluctuans, recorded in southern Vietnam, and N. fulvia, N. tullia and N. intermedia, all three recorded both in the north and in the south. I have only seen intermedia once, in Cuc Phuong, Ninh Binh Province, and N. fulvia was very very common around Ba Be, in rice paddies, but otherwise I have seen it only once at Tam Dao National Park and once at Cuc Phuong, all in July and August, although that may be more due to the fact that I visited Ba Be in July than that it is restricted to those months. And N. tullia, which apparently is a very common species in for instance Thailand, I saw only in Van Long Nature Reserve, although there is was common where it occurred, which was in grassy shallow pools. These are attractive libellulids, with colorful wings.
I admit, the photos are not the best. I promise to do better next time I run into them.

|Another male N. fulvia at Ba Be|
|Neurothemis tullia, female, with a striking wing pattern, not easy to overlook|
|Neurothemis tullia, male, likewise, at Van Long Nature Reserve|
|Female Neurothemis intermedia, with striking abdominal lines, but no obvious wing markings. Hope to see a male soon!|
