Overview

Distribution

Range Description

Orthetrum trinacria is widespread throughout the whole of Africa, except in the tropical rainforest, and the Middle East, and reaches the south of Europe. The easternmost localities are in western Iran, the northernmost ones in northern Sardinia. Former records from Anatolia are doubtful but recent authenticated records from northern Syria, southern Turkey, Greece, Malta and south west Iberia point toward a recent expansion and increase in density of the species to the north, probably due both to climate warming and construction of new man-made pools which are promptly colonized.

Habitat and Ecology

Habitat and Ecology
Orthetrum trinacria is well adapted to various fresh and brackish slow-flowing and standing waters, including flood plain backwaters (oxbow lakes, seasonally inundated depressions on river sides), pools and permanent sections of discontinuous and temporary flowing rivers, large man-made dam lakes, large permanent rivers, irrigation ditches and collecting channels and cisterns in oases. It is still able to develop under high salinity (150% of that of sea water (Suhling et al. 2003)). The larval period is short so that the species is able to reproduce successfully in temporary water bodies. Orthetrum trinacria is therefore well adapted to littoral dune lakes and desert and semi-desert environments with temporary waters showing increasing salt concentrations from the rainy season to the dry season.

Conservation Actions

Conservation Actions
This is a widespread and common species and no specific actions are required at the global scale. However, local declines may occur due to pollution, agriculture and water abstraction. Taxonomic investigations about the status of Iraqi populations would be recommended.
