Yellow-Winged Darter Sympetrum flaveolum
Common in southern and central Finland, becoming progressively more scarce up north. Flaveolum is usually most abudant in southern coast and can be extremely numerous on good years. Apparently there are influxes from Baltic every now and then, as species can be inexplicably scarce in some years, only to appear suddenly in large numbers next year and vanish again.
Can be encountered practically everywhere. Breeds in standing waters, especially shallow pools, bays and wet meadows, where thousands of emergent individuals can be recorded on a good year.
Flight period: June - October, main flight period late July-August.
Male. Sulka Haro
