Skimmers

Orthetrum sabina

Slender skimmer

This dragonfly's swollen, club shaped abdomen base is unusual among skimmers, and it perches boldly on exposed twigs while hunting other dragonflies and butterflies.

Size60 to 85 mm wingspan
WhenApril to November

Adults are greyish to greenish yellow with black markings, green eyes, and a distinctively swollen abdomen base that narrows sharply behind the third segment. Wings are clear with a small dark spot at the base of the hindwing.

It perches motionless on dry twigs and shrubs for long periods before darting out to catch smaller butterflies and dragonflies, and breeds in a wide range of still waters from puddles to ponds across a huge range from the Mediterranean to Japan and Australia.
