Coenagrion hastulatum
In 3 days ~40% in a week ~70%
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. Wikipedia →

Possible
About 20% of wildlife watchers report a Spearhead Bluet sighting in Cairngorms National Park on a given day, based on 41 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 42nd most-seen of the 300 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June
In that month about 30% of wildlife watchers report a Spearhead Bluet in Cairngorms National Park on a given day, against under 5% in August to April, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Spearhead Bluet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Spearhead Bluet sightings, Cairngorms National Park has the highest daily chance: about 20%. Next come Pyrénées National Park (France, under 5%) and Cévennes National Park (France, under 5%).

GBIF citizen-science records
It is estimated from how often the Spearhead Bluet is recorded against all the insects logged in Cairngorms National Park (41 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
