Orthetrum julia (Julia Skimmer)

Orthetrum species are decidedly tricky in Southern Africa, there being quite a few lookalikes from which to choose. There is excellent help available here.

We spotted our suspect species on our way down from the Waterberg Plateau. When I was snapping these, I thought I was looking at O. chrysostigma, which I am familiar with from Spain, so superficially similar does it look. I couldn’t see any “Epaulet” but that tends to get covered in pruinosity in older males. However, the wing venation and pterostigma colour (dark) showed these to be O. julia.

There are two subspecies recognized: O. j. falsum and O. j. xxxxxxx. So far, all ours are O. j. falsum.
