butterfly parasites

[Ard108]

Greetings all,
    I have been raising leps for a few years now and have acquired quite a
few parasites (various Diptera and Hymenoptera I believe) that emerge from
the caterpillars and pupae.  It's time I try to identify them.  The searches
I have run so far are a bit disappointing.  Can anyone point me to the books
I am looking to read?  I live in the San Francisco Bay Area, so Western
North American information would be best, yes?  Or can some of these be
imported controls?
    Advance thanks for any help.
                                                Brian
