The KEELED SKIMMER (Orthetrum coerulescens) is a small darter like dragonfly that is commonly found in acid, boggy areas. The images below were taken at Thursley Common on 1st July.
Males are distinctive with their blue slender, tapering abdomen. Mature males might be confused with other blue libellulids - Black-tailed Skimmer and Scarce Chaser both have a black tip to the abdomen; on the Broad-bodied Chaser the abdomen is much broader and flattened and both species are larger than the Keeled Skimmer.
Typically when resting the wings are gradually depressed and twisted forwards. The flight season lasts from early June to late August.
I watched a male and female flying together in the wheel (copulation) position and they fortunately decided to rest briefly on the boardwalk before flying off to settle low down in the vegetation.
The other species seen in good numbers was the Four Spotted Chaser and I'll post some shots soon...FAB.
