My juveniles are really grown up now - came in and found them in amplexus! These guys were born last year, and the female is now about 4.5 inches/200 grams. Its not clear to me that she knows or cares that she is "mating" - she eats, soaks, hops around like there's nothing sitting on her. Reminds me of the lyrics of an old pop song:
"cause you don't really love me, you just keep me hanging on"
