The photos aren't very good, and it's very brief, but this one little list has inspired me to hike the San Gabriel Mountains more than anything else. Why? Because I had no idea there were records for some of these butterflies up there, and I like the idea that something rare and extraordinary might be just around the bend.Organizations and Listserves

Check out the new-and-improved website - very nice!The International Lepidoptera Survey

Has great resources like Ken Davenport's update of Emmel and Emmel's classic 1973 book, The Butterflies of Southern California. Also has Davenport's official date ranges for California butterflies. This tells you the normal times a butterfly should be flying and what the early and late records are down to subspecies level.There are two listserves covering our area. The digests are worth reading even if you don't want to join in:
