The black-tailed skimmer, Orthetrum cancellatum, is a dragonfly of Europe and Asia. It occurs nearly all of Europe except northern UK and Scandinavia; to the east, the range extends to Kashmir and Mongolia. The adult male has a blue abdomen with a black tip and transparent wings, and the female has a yellow (later: brown) body with black bands along the abdomen and transparent wings. Even the immature males look that way.
