Whilst birding Deffi Park I found a couple of Slender Skimmer Orthetrum sabina along a small watercourse. They are a common dragonfly in Saudi Arabia, that is a very active hunter, found mainly in oasis and overgrown riverbanks and wetland areas. It is a medium-sized dragonfly with a wingspan of 60-85mm with adults being grayish to greenish yellow with black and pale markings and green eyes. Its abdomen is greenish-yellow, marked with black. Females are similar to males in shape, colour and size. It is widespread, being found from south-eastern Europe and North Africa to Japan and south to Australia and Micronesia.
