This is a dark colored adult male Leopard Rat Snake.
Due to the corn snake’s beauty and genetic adaptability a great many folks once frightened of, or at least impassive towards, snakes have not only become snake owners, but rave about the beauty of their captives as well. But comparatively few of these same keepers are aware that there is another rat snake that is as pretty as our corn snake, but is a bit more difficult as a captive and is much less readily available, This is the beautiful European Leopard Rat Snake, Zamenis situla. This like many other rat snakes world-wide used to be in the then cosmopolitan genus Elaphe.

In colors, patterns, and size this snake may vary somewhat with females being a bit longer, somewhat heavier of body, and more brightly colored than the males. Adult size varies from 26 to 36 inches. The ground color varies, seemingly by locale from dusky gray to bright gray, or occasionally to a golden gray. The black-edged dorsal blotches are often a bright red but, especially on males may be dusky red. Lateral spots are black. Patterns vary from a single row of dorsal spots to a double-row, or may be a combination of the two. Some individuals may have a double row of solid rather even edged stripes, or have a combination of blotches and stripes.

Our adults were rather reluctant feeders on laboratory mice, but eagerly accepted captive bred cotton mice (Peromyscus gossypinus) when offered.

An oviparous species, eggs may number from 2 to 8 in each clutch.

As you can see, Leopard Rat Snakes can be, and usually are, a bit more finicky than our corn snakes, but are well worth the extra effort put forth.
