I have a lot of passion flower vines that have a symbiotic relationship with gorgeous Gulf Fritillary butterflies. Each year, the butterflies show up and lay eggs on the vines, the caterpillars hatch and eat the leaves, and then pupate until the following spring. Except this year; no butterflies, no caterpillars. Not a one.

I don't use any pesticides on my property. My place is in the Sierra foothills. The only thing I can imagine is that last winter was a record one for rain. Did the wet weather kill the pupating butterflies? They are gorgeous (I'm trying to find a photo to attach) and I miss them!

They are beautiful...sorry they weren't there this yr.

My area has had a significant decrease in all types of butterflies, where 5 yrs. or so they were plentiful. I was told habitat loss but yours might be for others reasons...I don't know. Your local entomologists would know, do you have a college nearby? Or ck a university website.

I saw hundreds of monarchs and fritillaries on the coast near Charleston last weekend.
