Habitat

It mates in standing water bodies, which are clear and sunny and have little shore vegetation. It can often be found in lakes, reservoirs, artificial ponds, big pools, wide river and stream pools on the lower courses, gravel pits and flooded quarries.

 

Way of life

They fly low, often following mammals, or, even, humans. They can move dozens of metres like this, as it seems to help them catch their prey. This species, above all females, frequently rest on the ground, where they are difficult to be noticed. It is less common to see them resting on plants, but they can be seen on timber and dry branches which are in water or on the shore. Their position is horizontal and they hold their wings spread out in the shape of a cross.

 

When to see this species

In Málaga, it flies from June to September, but it can occasionally be seen in April, May, October and November.

 

Where to see this species

It is confined to specific location but it can be seen all over the province. It has been recorded on stages 18 and 19 of the Great Málaga Path, which go past lakes Fuente de Piedra and Campillos. Both colonies depend on the presence of water in this kind of lakes. It is likely to be found on other stages too, especially on those that go round reservoirs, like stages 19, 20 and 21.

 

Similar species

The female can be confused above all with Selysiothemis nigra.

 

Conservation status

The species is not endangered nor is it particularly protected by the current environmental law.
