Description:

Slightly less cooperative than her male counterpart was this female Blue-tailed Damselfly lurking deep in the vegetation.
I think this is what Dijkstra/Lewington calls the B-type female but which seems not to mention infuscans which I'm seeing elsewhere but not in my books. Curious.

"B-type"/Infuscans

I don't know for certain why Dijkstra chose to call the colour forms "A-type", "B-type" etc (you'd have to ask him! ;o) ), but I suspect that it was to allow easier comparisum between the similar colour forms of other Ischnura species. For example, the equivalent form to the f. rufescens-obsoleta of I.elegans, is far more orange in colour and apparently may be known as f. aurantiaca (like Small Bluetail/Scarce Bluetialed Damselfly, I. pumilio) in the Iberian Bluetail, I. graellsii.

A wise computer scientist ...

... once said, "the nice thing about standards is that there are so many to choose from".

I think the same may be said for critter names. :)
