My only "theme" is to get them all! lol!
Seriously, I had in mind to collect a representative pair from each species of kingsnake.:Lampropeltis (getula,calligaster,alterna, mexicana, ruthveni,triangulum, and zonata). I have long since done that and am on my way to getting a whole lot of subspecies as you might guess. One of my targets this year is L.triangulum micropholis. A toughie!
