Butterflies of San Mateo county, and those that are missing

I've been slowly working on a butterfly list for San Mateo county, primarily to teach myself something about butterfly distribution and flight timing, but also to accompany a set of lists of other taxa that Sequoia Audubon will be including on its website. Prompted by kueda's question on my last post here, and aided by robberfly (who loaned me the classic John Steiner dissertation, Bay Area Butterflies: The Distribution and Natural History of San Francisco Region Rhopalocera {CSUHayward, 1990}), I can now present a list of those butterflies which do occur in San Mateo county, but have not yet been represented in this project.

Two things to remember - First, I have NO IDEA what I am doing! I am still a rank beginner butterfly student, so please, correct me in future messages where I am wrong. Second, it strikes me that the citizen-science call to not fear duplication is especially fitting for butterflies, because of issues like fragmented habitat, flight timing, and multiple generations within a year. So please, always share butterfly pictures you obtain. But, three, be on the lookout for these species, especially, in San Mateo county. Local knowledge is power!

Dammit, I actually saw a Sara Orangetip flit by the last time I was in SM county. Didn't have a net, though, and they're devilishly hard to photograph without one.

Yes, I've had them, too, but not wanted to include a photo-less entry. They may be the most surprising miss on this list, along with Gorgon Copper, Western Tailed-Blue, and Coronis Fritillary.

I just entered an Oreas Comma this week.

Flutter away with those adds, dpom! Cannot go on butterfly walk tomorrow - get some more for the project, please!

I'll do my best. I also had Satyr Comma in the project, but it would be good to double check the id with Liam. I did see a Sara Orangetip at Edgewood on Thursday, but I haven't finished with the photos yet. Don't know if it came out or not.

OK, so I've removed Oreas and Satyr Commas from the needed list. I will try to keep this list updated to the best of my ability. The closer we get to completion, the better, as we can then produce a photo-guide to the butterflies of San Mateo County.

You can cross Mission Blue off the list!

It is done! Congrats on a real beauty today!

Thanks to dpom, Greenish Blue has also been found and entered!
