Resting black-tailed skimmer ♂ - close-up of nature's belly dancer

Extreme close-up of resting dragonfly, black-tailed skimmer (Orthetrum cancellatum L.), male. Their tissue areation (moving abdomen to improve airflow around body and enhance tissue oxygenation) looks pretty basic, when looking from the top, but in side view, it's a quite mesmerizing dance! Later you can see close-up of face, this time it reminds me lip smacking of old people.
