I'm raising 9 Giants and 3 of them formed their chrysalis today! :-) Last year was my first year to have any host plant for them and I only had one cat the entire summer. This year, my Rue has gotten HUGE - 3 1/2 tall by about 5 feet wide and I keep finding babies on it. I haven't spotted an egg or a female laying eggs. My daughter has developed a keen eye for spotting the hatchlings. :-)
I'm hopeful that there will many more.
