The Banded Groundling is a small dragonfly of African origin which only occurs in a few scattered areas in Iberia, on Sicily, and on Sardinia (which is where we first photographed it). In Africa, Brachythemis leucosticta is known for accompanying grazing cattle; as the cattle move through the tall grasses and thereby flush out all sorts of small insects, their dragonfly companions find their prey presented on a silver platter.
This is how we first saw the species; a handful of males and females, flying low to the ground and looking very much like miniature tumbleweeds, followed us around as we walked along a large artificial lake. The species' most distinguishing features include the mature male's all-black body and black wing bands, and the creamy-white pterostigma which gives the species its scientific name. In fact, though, that pterostigma is bi-coloured; its outer edge is dark brown.
