Lilypad Whiteface Leucorrhinia caudalis
Common, but local, in southern and central Finland. Favours calm bays, lush lakes, sometimes even acidic and peatmoss ponds. These nearly universally have floating vegetation, such as lilypads. Compare to similar but more common Dark Whiteface Leucorrhinia albifrons, from which caudalis differs by having a flattened abdomen. Male LPWFs also have a white pterostigma (not 100% reliable!)
Flight period: mid-June - early August.
Male. Sulka Haro
