They mate from November through March with a peak in mid-November through late December.
Habitat selection varies seasonally.
Because the cover requirements of indigo snakes change seasonally, maintaining corridors that link the different habitats used is important. Burrows need to be in areas where there is no flooding. These piles are often destroyed for cosmetic reasons but should be left intact because they provide important hiding cover for both the snake and its prey. Humans represent the biggest threat to indigo snakes. Highway fatalities, wanton killings, and overcollection for the pet trade adversely affect indigo snake populations.
