Appearance
The adult male has a blue abdomen with a black tip and transparent wings, and the female has a yellow body with black bands along the abdomen and transparent wings. Even the immature males look that way.
Distribution
This species has expanded its range, assisted by the creation of gravel pits which give it the extensive open unvegetated areas it prefers. It was first recorded in Great Britain in Essex in 1934. It is decreasing rapidly in the Maltese Islands.References:
