How to Identify the Meadow Viper (Identification Guide)

Key identifying features

The meadow viper (Vipera ursinii) is one of the smallest European vipers, notable for its comparatively slender, less robust build than other vipers, a narrower head, and a crisp, well-defined dark zigzag stripe running along its back.

Coloration & pattern

Ground color is typically grayish, tan, or light brown, sometimes with olive tones. A dark brown to black zigzag band runs continuously down the spine, generally narrower and more evenly edged than in bulkier viper species. A row of smaller dark spots is often present along each flank, and the belly is usually dark gray to blackish, sometimes with pale flecking.

Head, eyes & scales

The head is triangular but noticeably narrower and less bulky than in larger viper species, and is only moderately distinct from the neck. Dark markings, sometimes forming a V or paired streaks, may appear on top of the head. Pupils are vertical, and body scales are keeled but the overall scale texture appears finer given the snake's smaller size.

Size & body shape

This is a small viper, with most adults measuring just 35-50 cm, rarely exceeding 60 cm. The body is more slender relative to its length than other vipers in its range, giving it a lighter, less thickset appearance while still retaining the characteristic short viper tail.

Range & habitat where you'll see it

The meadow viper occurs in fragmented populations across parts of France, Italy, the Balkans, and eastward into Central Asia, depending on subspecies. As its name suggests, it favors open grassland, meadows, steppe, and montane pastures rather than the rocky slopes preferred by many other vipers, often at moderate to high elevations.

How to tell it apart from look-alikes

Its smaller size and slimmer build distinguish the meadow viper from the bulkier common adder and asp viper found in overlapping regions. The zigzag pattern tends to be narrower and more precisely edged than in these larger relatives. Non-venomous grassland snakes have round pupils, smooth scales, and lack any zigzag dorsal pattern, making the combination of vertical pupils and a fine zigzag stripe a reliable way to recognize the meadow viper even at its smaller size.
