Coenagrion hastulatum

Coenagrion hastulatum, the northern damselfly or spearhead bluet, is a damselfly in the family Coenagrionidae.

The species is widespread and common in northern Eurasia but is restricted to elevated or bog-like sites towards the west and south. In Britain, it is confined to a few small lochans in Scotland.

Coenagrion hastulatum is 31 – long.

The specific part of the scientific name, hastulatum, from the Latin hastula (small spear) is because of the distinctive markings on the second segment of the abdomen that resembles a spear.
