That's wonderful!

Yay!!! Congratulations!!

Update: I later found 2 more chrysalises, and all of them hatched out - found them all empty, so presumably butterflies were healthy and flew away. Sorry I missed seeing them emerge, but hopefully they'll be back to lay more eggs.

I enjoyed that process, too, some years ago. Unfortunately, birds came along and stole the fat chrysalises before my eyes!

Oh that's so sad, rhizo!

I've seen wasps attack chrysalises, and larvae as well, but not birds.

Carol, yes empty chrysalis shells allow some confidence that they beat the odds. Better chance when you harbor caterpillars or at least chrysales. With sulphurs, I even have to get eggs before they disappear. To see a tiny caterpillar is a rarity, and a large one is a never.

I have nothing for Giants to eat, but they come often for nectar..

I've had lots of eggs but no surviving sulphur caterpillars on the senna in our butterfly garden - in my case it's wasps. The caterpillars only manage to make it to adulthood in the winter, when the wasps are dormant.
