Color pattern remarkably variable with continuous variation and many intermediate forms (Fig. 19). Typical pattern without thoracic bands but with 2-4 irregular, angled bands on lateral margins of abdomen. Color also variable ranging from white, yellow, orange, or sometimes light blue or purple background with black, dark blue, or brown pigment forming bands. Dark bands outlining posterior and lateral margins of Th. 2 and Th. 3 sometimes present. Apex of femora usually with a dark patch. Head either entirely blue or purple, or lacking all pigment except for the eye patches. Dark patches of pigment usually occur on distal end of antennal segments 2-4. Juveniles usually with light blue pigment background and faint brown abdominal banding.</paragraph>
