Yup, the Blues are all pretty similar. I've seen the Eastern Tailed Blues up in WV where there seems to be tons of them, but I live a little too far south for them.
I can't remember if I mentioned this, but three clutches of the Pipevine Swallowtails have hatched! They're happily munching away. If I can get them to about third instar (medium size), I'll probably take some to MOSI since I don't think I have enough food for that many caterpillars.
