I have at least three Italian immigrants living in my backyard. At least, that's as many as I've seen at once. They're quick as lightning, so they're hard to count. But as the sun grows stronger, they come out to bask, and although technically they're an invasive species, so far they cause no harm, carry no parasites, and oh, BTW, they eat my aphids so they're ok by me.
As I say, they're quick, and awfully shy, so you'll have to zoom in on these to get a good look.
