First is female.
The second appears male to me.

Yeah, me too. Looks like you got yourself a pair of Thamnophis sirtalis parietalis'. Red sided (not to be confused with CA red sided)

Garter snakes display sexual dimorphism. We don't need no stinkin' probes! Just pics. It's easy to miss the inverted hemipene on a male, causing it to probe as female, if you're not far enough over to one side or the other or if the probe is just a little to big in diameter.

Thanks Guys chuffed to have a pair .First dabble into herping was with garters around 20 years ago and decided to get back into them.I seem to remember being told back then a way of spotting sexual difference was by way of the anal plate being curved for female and straighter for males.Or is that me imagining things in my old age
