Thank you Reiner Richter for confirming the id of this species for us General Species Information: Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills, the Flinders Ranges and elsewhere The recent male we measured was ~47mm long with ~77mm wingspan. These can be difficult to distinguish as both genders are yellow and black when young. As they age they turn blue. The males go a bright, light sky blue; the females become grey blue. All males have 3 longer appendages on the rear, the females 2 shorter appendages. If you are able to take a ventral photo, the males have additional genetals near the join between body & tail. This is what the female connects to when they are mating. There is another very similar species found in SA, called a Black-headed Skimmer (Crocothemis nigrifrons). As the name suggests, the male has a black head & face (the blue skimmer has a yellow face). The female is very pale grassy brown, with a think black line down it's abdomen. | |||||
