Thursday, July 10 2014Bulgarian rat snake update
The Bulgarian rat snake, Elaphe (quatuorlineata) sauromates, is also known as the Eastern European rat snake and the European blotched snake.
 Once considered the easternmore of the two subspecies of E. quatuorlineata, it is now most often considered a full species designated by the binomial of E. sauromates. Although lengths of more than 8 feet have been verified, most examples range between 4 and 6 feet in length. Unlike the westernmore E. quatuorlineata that undergoes extensive ontogenetic (age related) color and pattern changes, the Bulgarian rat snake retains its juvenile blotched pattern throughout its life. My pair of Bulgarian rat snakes are both about three-and-a-half feet in length. After a long hibernation they bred in 2014 at three-and-a-half years of age.
 Of the seven eggs, five were fertile and began hatching after 51 days of variable room temperature incubation.  The last one hatched after 56 days. The hatchlings will be going to friends who, like me, are interested in perpetuating the various European Elaphe in the American pet hobby.
