The ruddy darter is to be found in temperate regions throughout Europe as far east as Siberia and as far south as the northern Sahara. Its conservation status is regarded as secure, and indeed numbers seem to be increasing in some locations such as central England. 
It is presenr in the following countries: Albania; Algeria; Armenia; Austria; Azerbaijan; Belarus; Belgium; Bosnia and Herzegovina; Bulgaria; Croatia; Cyprus; Czech Republic; Denmark; Estonia; Finland; France; Germany; Greece; Hungary; Ireland; Italy; Kazakhstan; Kyrgyzstan; Latvia; Liechtenstein; Lithuania; Luxembourg; Macedonia, the former Yugoslav Republic of; Moldova; Monaco; Montenegro; Morocco; Netherlands; Norway; Poland; Portugal; Romania; Russian Federation; Serbia; Slovakia; Slovenia; Spain; Sweden; Switzerland; Tajikistan; Tunisia; Turkmenistan; Ukraine; United Kingdom; Uzbekistan. 
The ruddy darter can reach a body length of 34–36 millimetres (1.3–1.4 in) and attains a wingspan of up to 6 cm. These dragonflies are smaller than the Common Darter. They have black legs and the wings show a brown pterostigna and an orange color at the base of the wings. Two evident black marks are located on segments S8 and S9 of the abdomen.
The head, thorax and abdomen of the mature male are vivid red, while the female is slightly smaller, and is a golden-yellow colour with black markings. The blood-red color of the males develop with maturity, together with a red frons and a red-brown thorax.  The abdomen widens for the final third of its length and shows a marked pinched section where it joins the thorax.
The all-black legs of the ruddy darter distinguish it from the otherwise very similar common darter (Sympetrum striolatum) and vagrant darter (Sympetrum vulgatum), both of which show yellow stripes on their legs.
The ruddy darter can be found between the months of June and November.  Mating takes place on the wing, with the coupled pair performing a dipping flight over the water. The female jettisons her fertilised eggs at the water surface by alternating movements of the abdomen. The male will hover nearby during this period and protect the female by driving off any approaching males.
