The Latest

June 6, 2017 - Quick update after a busy weekend. I went to the Big Bear area and hiked a road that leads from the Sugarloaf trailhead all the way to Wildhorse Meadows, and was lucky enough to come across Callophrys sprinetorum spinetorum, the Thicket Hairstreak. This was my first sighting. I also got good looks at the many California Tortoiseshells there. I may have more from that day presently. I spent that night in Palm Desert and spent the next day at Cactus Spring Trail, where I got a nice shot of a fresh Great Purple Hairstreak - Atlides halesus corcorani. I also came across a larva of - most likely - a Ceraunus Blue on Astragalus palmeri. I've added another photo of a Small Checkered-skipper from that day and revamped that page as well.

May 29, 2017 - I'm updating this site pretty comprehensively, in part to make it mobile-friendly and technically up-to-date, but also to improve and expand the content. It's going to evolve a bit as I get the look and feel right. Going through each page with a fine-tooth comb will take awhile, but I think it will be worthwhile. For instance, I'll be adding general information to the individual butterfly and plant pages above the photos. I collapsed the books and links pages into one "resource" page for simplicity. The six family pages will have to change so I can get away from using tables in my html - which aren't device friendly in the least - but I haven't settled on exactly how I want to do that yet. Just an FYI - changes are afoot.

I've also made it out to the field a few times lately. Here are some new photos of not-new species: a California Hairstreak from Icehouse Canyon in the San Gabriels below Mt. Baldy (I wanted spinetorum); nominate Euphydryas chalcedona from the same day; Pontia protodice from Big Bear (I saw E. hyantis andrewsi but couldn't photograph it); and I added to a plant page - the subscaposum variety of Wright's Buckwheat (looking for dialeucoides in vain). Out in the desert a couple weeks ago, I learned that Pontia beckerii uses Sisymbrium orientale at Cactus Spring Trail, where it's had a good year; I'd wondered what, if anything, it could be using since the host I associate so much with it - bladderpod - doesn't grow there. I feel like I'm just scratching the surface in terms of what there is to learn.

May 1, 2017 - Had a few days off, so I headed out to the desert again to take a longer look at Cactus Spring Trail, which I did on Thursday and Friday, and on the way back on Sunday I stopped at a new spot for me: the Whitewater Preserve in the San Gorgonio Wilderness, managed by the Wildlands Conservancy. This is the same organization that manages the Bluff Lake preserve, one of my favorite places to visit.

Not far along Cactus Spring Trail, I came across the distinctive larva of a Spring White (Pontia sisymbrii). Butterflies were plentiful; I've mostly been adding only new things to this site but I took nearly 500 photos; here's one of a butterfly that isn't new but it's one I'm always happy to see: Papilio polyxenes coloro.

I got something new at Whitewater by following a Becker's White as it oviposited on its host plant, bladderpod, which is common there. The egg photo is about as good as I'm likely to get in the field without a tripod.

April 25, 2017 - Back on March 3rd, I found a larva of Euphydryas chalcedona hennei that had attached itself to a leaf on Cactus Spring Trail. Returning nearly 4 weeks later, I saw that the butterfly had emerged.

April 22, 2017 - Cactus Spring Trail is really fantastic right now after all the winter rains. Within moments of getting out of my car at the trailhead, I'd seen several species of butterfly and came upon a last instar larva of Papilio polyxenes coloro, the Desert Swallowtail. Several adults were out as well. I've seen some "firsts" for this particular trail this spring, including this Sleepy Orange - Abeis nicippe. The usual suspects were out in abundance and the plants are doing better than they have in years. It's been good to see creeks running that have been dry the last several years.

Introduction

Nearly all these photographs of butterflies and their host plants were taken either in my garden, the local park, or (most often) in wild areas within a few hours of my home in Long Beach, California. Butterflies are a life-long interest of mine, and I started photographing them seriously beginning in the summer of 2005. I've listed on six pages - one for each family represented locally - all the butterflies in my area (to subspecies level) and their larval host plants, with links to pages I've created for each butterfly. Some of these are rarely seen and a few are even endangered species, and thus a challenge to find and photograph, but I've included them on the list if they fly in this region. In fact, the challenging butterflies are often the most interesting. There are, of course, various difficulties with creating a comprehensive list to subspecies level, and so it tends to evolve as I learn more or with taxonomic changes.

In my garden I may see fifteen or so different species in a typical year (I've seen twenty-five species there over the years). But by day-tripping to various places no more than a few hours' drive from my house, I can multiply this number many times over. In fact, there are 259 taxa that I've listed for our area (this number has grown with the addition of more Kern County butterflies). The lists on this site are all of these butterflies - those I'd like to photograph that are in my area or a 'reasonable' drive from where I live. My goal is eventually to see and photograph them all (I have 188 as of June 2017), as well as their host plants. Some that are very rare or only occasionally stray into our area are common in Arizona, and I've included a few photographs from there.

Southern California is an incredibly diverse place to explore and enjoy the natural world. Mountain forests, beaches, wetlands, grasslands, deserts, meadows, even islands - all are within easy reach with their various lepidopterous inhabitants. I've learned to appreciate these places, and I hope my photographs help convey some of the richness of our native flora and fauna.
