Bright blue is a popular colour amongst odonata. In damselflies we see this in the common blue and azure damselflies and three or four other less common species and in dragonflies there is the mighty emperor of course as well as keeled and black-tailed skimmer but this beauty is the impressive male broad-bodied chaser (Libellula depressa). If you see a dragonfly that is bright blue it is always worth a closer look just to make sure you do not jump to conclusions.
The broad-bodied chaser is quite common and is one of the most likely blue dragons you will see. The male is very different in colouring to the female which is olive green. The broad-bodied chaser is best identified through its ... broad body! The skimmers are much more pointed towards the tail and the emperor is longer and an even width along its long body.
This chap is fiercely territorial and it will often take over a small pond and defend it against all comers, apart from attractive females of its own kind of course who are very welcome and are greeted by being ceased and mated with in mid air! Often, however, the female will then find a pond that is unattended by a male and lay her eggs in peace and quiet.
This is one of the earliest dragonflies to appear and can be seen around ponds everywhere, frequently newly formed or newly cleared ponds.
