- In males the back of the abdomen is mostly black, whilst segments 8 and 9 are all blue.
In males the underside is bright green especially on the head and thorax (see side view)
- The blue is of a darker shade than similar species
- Females are dull green with black markings
- In females the hind margin of the pronotum has a prominent raised point (see comparison of pronotums of blue damselflies)

Famous quotes containing the word appearance:
“Men of all professions affect such an air and appearance as to seem to be what they wish to be believed to be—so that one might say the whole world is made up of nothing but appearances.”
—François, Duc De La Rochefoucauld (1613–1680)
“A bureaucracy is sure to think that its duty is to augment official power, official business, or official members, rather than to leave free the energies of mankind; it overdoes the quantity of government, as well as impairs its quality. The truth is, that a skilled bureaucracy ... is, though it boasts of an appearance of science, quite inconsistent with the true principles of the art of business.”
—Walter Bagehot (1826–1877)
“What! Would you make no distinction between hypocrisy and devotion? Would you give them the same names, and respect the mask as you do the face? Would you equate artifice and sincerity? Confound appearance with truth? Regard the phantom as the very person? Value counterfeit as cash?”
—Molière [Jean Baptiste Poquelin] (1622–1673)
