Common, early season dragonfly. Inhabits a wide variety of still waters and can be present in large numbers at established sites.
In Gateshead, Kibblesworth Brickworks Pools holds by far the largest population, but small numbers can be found at Stargate, Far Pasture and Gibside, with the flight season being late May to early August.
|Male Four-spotted Chaser|
In the field they are dull in colour but conspicuous by behaviour, perching
openly, speeding out over the water to feed and chase rivals.
Diagnostic dark wing-spots at the nodes give them their name.
|Another male, though sexes are alike, immature females are a lot brighter,|
dulling with age, when they can be told apart by the slightly fatter abdomen
and longer, inward-pointing anal appendages.
|Emerging Four-spotted Chaser|
Takes place on marginal emergent vegetation usually
in early morning late May and through June.
Larvae take two years to develop.
|This picture shows the much more colourful thorax, and note the|
dark smudges trailing from the pterostigma, making this individual
the rare prenubial form, though the reason for its existence
|This unfortunate male was plucked from the sky at Kibblesworth by a |
female Emperor. Apparently this is quite common as both species
patrol at similar heights (70-100cms) making encounters inevitable.
