Lots of fritillaries here in the Dallas, Texas area too! And like you said... the caterpillars nearly stripped my passionflower vine! But, they were gladly forgiven and perhaps I just need to plant more vines! Love to see the butterflies flitting about in the garden and love it when the sun hits that silvery underside of their wings! And... "click" goes the camera!

There are fritillary caterpillars on my passion vine in Sonoma.Will they overwinter as chryssalises or continue on to complete their life cycle as a butterfly? I am worried about the cold weather snd if it will affect them as butterflies.

Thank you for your comment. Art Shapiro, UC Davis distinguished professor of evolution and ecology, responds: "The Gulf Frit is a subtropical and tropical bug and has no adaptations to survive cold winters. It will attempt to breed all winter and any stage can survive so long as temperatures stay above about 21-22F, which is lethal to them all. One can protect garden colonies just as one would protect a sensitive plant, by putting a cover over them!"

Last year a colony moved into my yard here in Morgan Hill. I have a giant purple passionflower and plenty of nectar flowers to feed both adults and their 'pillars.  
Oh to be a butterfly! they just eat, flutter, chase each other, flutter, chase each other and repeat... and so pretty! Let them 'pillars eat my plants as long as I get to enjoy the beautiful butterflies, flutter and fly.  
they all disappeared in November at that early frost at 32F and did not come back until April 1, 2021. So glad they did!
