The same with me in Petaluma -- many fewer than last year. But I harvest the eggs I've found immediately and bring them inside to metamorphose and then put them back outside. Then they come back and eggs on my Passionvine.

I do have Gulf Fritillaries on my Passionvine. Not as many as last year or year before but there are at least 4 at any time in the area: Vine growing on my lath house in a quiet / not disturbed area. Don't see any larva this year.  
 
I've been seeing yiger swallowtail butterflies for a few months now at least 2-4 each day. Found 3 full size larva about 3 weeks ago-on a large bronze fennel. Have not seen their chrysalis. Today I saw one adult flutter up out of area -- hoping it was one of my larva emerging.

Wanted to tell you not to worry... that I've got a ton of Gulf Frits, here in Pasadena, and the Passiflora to keep them munching without decimating the vines. But when I compare pictures with yours, it appears I've misidentified them? Size is right, but more white spots at the tips and some checkerboard at the edges.  
 
I've got a 12x12 metal sun shade (no canvas...all vines, but definitely a tent now). This butterfly bower "blooms" butterflies on almost any warm sunny day all year long. There's a volunteer apricot totally covered with another Passiflora, including 25' of adjacent fencing. That vine is engulfing a nearby "tuna cactus" as well.  
 
We (in the neighborhood) have also seen more Monarchs than in any years past. There's more native (and non native) milkweed growing now. At my place, they are sipping on an edible "Taiwanese spinach" type vine (on another arbor) with saffron yellow tiny dandelion-like blossoms that dry into teensy tutus.  
 
This type of landscape is fast disappearing. We are told we need "fire margins" now. Passiflora is not a plant for "managed city properties", and yes, is invasive. There's no good time to trim or tear it down without destroying the butterflies in various stages. There is also a massive white mulberry tree, likely from the silk worm bust at the turn of the century....and I keep that for the birds.  
 
Guess my place will just burn. Love your blog and pics and people! Many thanks,

I have NO Gulf Eritillaries in San Dimas. Most years I have many dozens, even hundreds. No caterpillars, no adults. At least we have a robust monarch population this year! Last year seemed to have an explosion of parasitic wasps... maybe that has affected this year’s butterflies.

Hello! I photographed a male and female today on our butterflybush in Chico, Ca. 7/20/2019.

I usually have a lot here in Houston, Texas every year on my passion vine but almost none this year. I also have a lot fewer pipevine swallowtails. I hope this is just a normal cycle.
