Habitat and way of life
The yellow-banded krait lives mainly in flat and hilly areas, more rarely in the mountains up to an altitude of 2300 meters. It occurs mainly in open terrain, in fields, in grasslands, in sparse forests and their edges and rarely in swamps and river deltas. The species avoids sunlight. Exposed to sunlight, she always tries to escape into the dark or she hides her head under her entwined body. During the day she is lazy to bite, but very dangerous at night.
