Papilio zelicaon

Chuck,
 
Last year was the first year I reared this species.  I'm seeing similar
results as well.  A large number of last season's pupae appear healthy but I
haven't had any of them emerge in months.  Though a good number came out
early on.  I wonder if it has to do with the over all cool temps in the SF
Bay Area this year?  After all, this was the first time it has snowed in
downtown San Jose since I was a kid (and we lived higher in the Santa Cruz
mnts then.)
 
Also curiously enough, I have a couple of chalcedon checkerspots that seem
to be delaying larval diapause.  I had them looked at by Jasper Ridge's
chalcedon expert and she was quite interested to see this.  I've been asked
to keep astute records on how they progress to see if they will actually
bypass the normal hibernation.  Again, I wonder if this could be a response
to cooler temps in that perhaps it has extended the season for the host
plant which would traditionally have dried out and been dead long since.
Interesting stuff.
 
Best wishes...  Laurel
