Keeled Skimmer.

Another dragon from my wanderings at Thursley Common in July was the Keeled Skimmer (Orthetrum coerulescens).

This is the male and when on the wing it is often easy to confuse this species with the Black-tailed Skimmer but that has a black tip to a much broader abdomen. At rest the other difference is the colour of pterostigma. As you can see (above) it is yellow on the Keeled but dark brown/black on the Black-tailed.

I didn't spot any females during this session so I'll have to wait until next year for another opportunity to bag one for the files.  FAB.
