Subject: Re: [NorWestLeps] San Francisco butterflies breeding times

=EF=BB=BFHi all,

First, I=E2=80=99m sorry to say that Shapiro=E2=80=99s book is not so good=
for Bay Area butterflies. The Bay Area info was obtained second hand and =
not reviewed for accuracy. Of course the info on the Central Valley is sup=

Second, I think folks may have missed the nuance of the request: info on b=
reeding periods, not flight periods. For many SF species the two are more =
or less synonymous: if adult males and females are flying, it=E2=80=99s bre=
eding season. The exceptions are for species that have a long-lived genera=
tion that diapauses. The overwintering generation of Monarchs is a well-kn=
own example. Others include overwintering or estivating nymphalids such as=
Mourning Cloaks, Satyr Anglewings, and some Vanessas. For those species, =
you may see adults during some times of year that are taking a break from b=
reeding until conditions are better for their kids.

seems the term gets applied to quite a range of genera, though mostly clos=
ely related ones in terms of what might show up in California (Gnaphalium, =
Pseudognaphalium, Gamochaeta, etc.). I don=E2=80=99t SF too well, but a qu=
