The biggest snake found in Virginia is The Black rat snake, Elaphe obsoleta obsolete. The length of this full-grown snake is 8ft. These black snakes are often seen in the fields, farms, and in uptown gardens. These are the ones we often find around constructions, foraging for rodents, little birds, and amphibians. These black rats are in a sense, quite timid, even though they are often seen all through the summer, when they face a threat, they may run for life frozen in fear.

Rat snakes are good friends of the farmers; they are helpful in controlling the number of pests which are a threat to the barns and in the fields. The acquisition of land for development, felling of trees, etc. are some of the reasons for the decrease in their territory. In spite of this they sustain with a good number. The people around are not aware of the details of these rat snakes, and as such, persist to view them as a threat to their lives.

Other than having the chin colored white, the black rat snake is totally black, simulating its name. The black rat snake babies are light gray with  black spots on its back. In the course of its growth, the color turns darker and darker, thus attaining its parent color. These babies are always erroneously pictured as Copperheads, since the design of their skin is similar. Even though a major portion of the body is black, a little shade of white is visible in its scales. Its belly too is white in color.

As a Pet


The Black Rat snake is no different from the other snakes, in the matter of laying eggs. In the midst of March and May, snakes start to come out of their hibernation in winter. The end of April and the beginning of May or start of June is the time when the male starts to find its mate. The male begins to hang around till the female passes by. Then by the use of pheromones, it communicates with the female and takes the lead in mating. The male snake reaches the female snake, brings himself in alignment with her and tries to enfold its tail round that of the female, keeping their vents almost near. Certain males grip the female with their mouths to keep her in position, thus obstructing her escape. Further the male inserts its erected hemipenes in that of the female’s cloaca; at this moment many tiny spines fasten the hemipenes steadfastly. The time for mating is just a few minutes or a fraction of an hour.
