Color patterns vary by population. Some are banded red and black dorsally and ventrally; some are striped pos- teriorly with two or four black stripes on an olive, green, or brown ground color; some are totally leaf green dorsally and pale yellow ventrally; others may have combinations of black and yellow or red checkered venters with two black dorsal.
