Tot 35-39mm, Ab 25-33mm, Hw 17-24mm. Average size and build for a Spreadwing.\n\nThe most widespread and numerous Lestes in many areas, probably because it is less partial to ephemeral habitats.\n\nOccurrence:\nOne of the commonest damselflies in most of Northern Europe across to japan, but (largely) absent from most of the south.\n\nHabitat:\nAlmost any standing water with ample reed-like vegetation. May be more numerous at recent shallow or acidic sites, but not specific  to pioneer, ephemeral or bog-like conditions.\n\nFlight Season:\nGenerally from mid-May to mid-October, peaking in August. Most emergence tends to be a week later than L. dryas.\n\nThis is a common Species in the Netherlands in the described Habitats.
