Look Alikes

This slender, all pruinescent blue species, is recognised in the field by its small size and blackish upper surface of frons. In O. abbotti, another all pale blue species, the front of the frons is distinctly spectacled (but distinctly lighter than in O. icteromelas) and viewed from above, light grey with black tracery. O. machadoi is very similar to O. hintzi, but when viewed from above, the nose of O. hintzi is blackish, but light grey in O. machadoi. Its wasp- like flight and habit of staying low to the ground, and rarely perching over water are also distinctive. Secondary genitalia with square-ended lobe on hamule is finer in structure than that of O. machadoi, and the hooks are very different.
