The queensnake (Regina septemvittata) is dark brown, with three slightly darker (often hard to see) stripes running down its back. A distinctive yellow stripe runs along the lower side of the body, and the belly is yellow with four distinct brown stripes. This species typically grows to 40 up to 60 centimetres in length.

Similar Species

No other Ontario snakes have a striped belly. Queensnakes are found in the same habitat as northern watersnakes. Young watersnakes are strongly patterned, but larger adults may be quite dark and have faint horizontal banding, whereas queensnakes have faint lateral banding, as well as the pronounced stripes along their sides.

This species is often found near streams, either basking or under rocks.

Queensnakes mate soon after emerging from hibernation in the spring. The females give birth to live young late in the summer. A brood consists of approximately eight to 14 young. At birth, the young are approximately 20 centimetres in length.

The diet of the queensnake is one of the most restricted of any snake; it feeds almost exclusively on crayfish that have recently moulted. In the spring and fall, queensnakes may bask communally, even in low shrubs. Little is known about queensnake hibernation sites.

Other names: Coluber septemvittatus, Natrix septemvittata

Threats and Trends

The profound changes to the southern Ontario landscape, including wetland drainage, forest clearing and increasingly high human density, all threaten the survival of the queensnake. Dams can make habitat unsuitable for this species by altering stream flow. Queensnakes are more sensitive to environmental contamination than many other reptile species; pollution and other changes to water quality can affect crayfish habitat and subsequently threaten queensnake populations.

Current Status and Protection

The queensnake is currently listed as Endangered under both the Ontario Endangered Species Act, 2007 and the federal Species at Risk Act. The species has also been designated as a Specially Protected Reptile under the Ontario Fish and Wildlife Conservation Act. These acts offer some protection to individuals and their habitat. The International Union for Conservation of Nature lists the global status of the queensnake as Least Concern. The species’ status was last confirmed in March 2007.
