Oregon red-spotted garter snake
Thamnophis sirtalis concinnus
This snake belongs to the same species as the red-sided garter snake, but differs in the details of its coloration, and in its range. While subspecies identity and range are still being debated by many herpetologists, some recognize the Oregon red-spotted garter snake as a distinct subspecies endemic to the Willamette Valley of Oregon.
In our studies of local snake communities, this is the snake we see most often. Like the red-sided garter snake, it does fairly well in captivity (but it may be illegal to collect them from the wild without appropriate permits, and we do not encourage keeping any wild animal as a pet) and is useful for laboratory studies.
