Coenagrion hastulatum
species of insect
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 31–33 millimetres (1.2–1.3 in) 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.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Coenagrion hastulatum”, the useful work is to connect “species of insect” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jun 24, 2026. The linked authority identifier is Q1935365. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
