The variable damselfly or variable bluet (Coenagrion pulchellum) is a European damselfly. Despite its name, it is not the only blue damselfly prone to variable patterning.
Its behaviour is much like that of the azure damselfly; it usually stays close to vegetation. Immatures are often found in adjacent meadows or uncut grassy areas.
Description[edit]
The male variable damselfly has a distinctive "wine glass" marking on the second segment of the abdomen. This is a black U-shaped mark with a black line joining the segment's narrow terminal black band.[1] (This distinguishes it from the Azure Damselfly which has the U-shape but no line connecting it to the terminal band.)[1]
