![]() ![]() Some friends have also recorded a couple of female variations additional to the traditionally documented five named forms, so those are now shoehorned in. Some folks confuse the immature male colour form, sporting a turquoise thorax, as being one of the female forms, so I’ve included that, too. Since a picture speaks a thousand words, here is a diagram trying to clarify the colours and development process. Here is my attempt at making sense of the resultant naming mess: Traditional Dijkstra who, in his otherwise excellent reference work, saw fit to assign them different names (and rather boring names that are difficult to remember, IMHO). 9:00 AM to 13:00 PM, and finally females oviposited mainly from ca.

There is a bi-coloured pterostigma on the front wings. (This makes much more sense because it is the mature form of rufescens.) Adult male blue-tailed damselflies have a head and thorax patterned with blue and black. The “traditional” names assigned to the five female colour forms have been modified such that one form, originally known as infuscans-obsoleta, is now referred to as rufescens -obsoleta.As if the confusion of having various colour forms weren’t enough, we now have naming confusion thrown into the mix. Of the five female colour forms, two are immature and three are mature. It’s a particularly delicate damsel but it’s the glittering array of five female colour forms that adds to the fascination and, I might say, complication.
