The Latest

bullet pointOctober 23, 2019 - I added pages for a few rare strays, whose photos are mostly from my recent foray to Arizona. They are the Texan Crescent (Athanassa texana texana), the Pearl Crescent (Phyciodes tharos tharos), and the Arizona Red-spotted Purple (Limenitis arthemis arizonensis). There are also new photos on the Queen, Snout, and the echo cinerea pages.

bullet pointOctober 21, 2019 - As part of a revision to this site, I've added pages for the Pima Orangetip, Anthocharis cethura pima, as well as the juniper hairstreak Callophrys siva siva. Both have photos from a spring, 2013, trip to Arizona, but these butterflies do range into southern California. As it happens, I just returned from several days in Arizona, after which I stayed in Palm Desert for a few days and hiked Cactus Spring Trail three days in a row. Needless to say, lots of photos coming. Briefly, Patagonia had some choice butterflies, and I had good days in the Santa Ritas and a really enjoyable stop at the Bryce Thompson Arboretum east of Phoenix. As a teaser, an Arizona Sister - Adelpha eulalia - posed for me on the road up Montosa Canyon. Closer to home, Cactus Spring Trail is having a good autumn, with several Agathymus stephensi easy to find each day; a Systasea zampa making an appearance; California Sisters were worn but out in numbers I'd never seen there before; and good fall flights of Euphydryas chalcedona hennei and Apodemia virgulti virgulti had me wondering whether there had been summer rains I was unaware of. The flight of Euphilotes dammersi dammersi is ending. Actually, that may just about do it for the year for me as well. I've already got a late January trip in mind, and that's just three months away.

bullet pointOctober 9, 2019 - I was fortunate to find and photograph MacNeill's Saltbush Sootywing - Hesperopsis gracielae in Blythe, CA. a few days ago. This was my first visit to the Palo Verde Ecological Preserve along the Colorado River, and my first encounter with this uncommon skipper. A few days later I drove up into the Mojave National Preserve via Kelbaker Road when I came across a nice Great Purple Hairstreak. Summer rains don't seem to have materialized there, so butterfly activity was poor. In between those two long day-trips I hiked Cactus Spring Trail twice, and it was doing pretty well considering it's October. Fresh broods of Euphydryas chalcedona hennei and Apodemia virgulti virgulti kept me company while I concentrated on Euphilotes dammersi dammersi and Agathymus stephensi, both of which only fly at this time of year. I've revised the pages for those butterflies.

Meanwhile, I've been doing a thorough revision of my southern California list. I've decided to define the area as all the counties south of the straight line that stretches east-west from the northern San Bernardino county line to the coast, in San Luis Obispo (see the map below). That brings rarely-seen species and subspecies of, for example, the remote eastern ranges of the Mojave National Reserve into play, as well as some coastal specialties from SLO and Santa Barbara counties that will not be easy to get. That's why this year I've made initial forays up to SLO Co., the Hualapais in Arizona, and now the Colorado River at Blythe and Granite Pass in the Mojave Reserve. When I started this site and project twelve years ago, I was getting photos at my local park and nature center, and places such as Big Bear were full of species I'd never photographed. Things have changed; the low-hanging fruit has been picked. The last few dozen butterflies that I need to complete this quest of sorts will require some planning and effort, and I'm very excited about the trips that lie ahead. California is truly beautiful, and chasing rare butterflies is a great way to experience its natural wonders.

bullet pointSeptember 22, 2019 - I finally was able to devote the time to go after Hesperia columbia, a rare skipper, and found a couple on a hilltop in Frazier Park today. It wasn't particularly sunny, but I was fortunate that it was just warm enough at times for them to fly. I've also updated the page for Heliopetes ericetorum, including some newer photos.

bullet pointSeptember 4, 2019 - Another new butterfly is the Coast Range segregate of Apodemia mormo near mormo. These are really beautiful, and while genetically different from the endangered langei from the Antioch Dunes, they look similar. And that look is different from anything else I've seen in southern California. I found them in a spot I learned about in Ken Davenport's writings: Davis Road near the border between the counties of San Luis Obispo and Kern. Quite a drive, but quite a butterfly. Its host plant now has a page as well.

bullet pointAugust 31, 2019 - A new addition is the hard-to-find Euphilotes pallescens elvirae, a species that flies in the deserts in the heat of August and September. Looking forward to more trips in September and October for some autumn specialties.

bullet pointAugust 22, 2019 - Just finished revamping the gallery. It's not completely done yet but it's close.

bullet pointAugust 20, 2019 - The Painted Lady page has been spiffed up a bit, including an introduction and a couple photos replaced. I should probably do that with the oldest pages as I get the time. Eventually I'd like to overhaul all of them, but it's not exactly a priority to be honest. So there. A Desert Swallowtail caterpillar from April that I happened upon when going through older photos seemed worthy of inclusion on the coloro page. It's at the very bottom.

bullet pointAugust 18, 2019 - I added a recent photo of an American Lady that was flying at Frazier Park. Another trip up to that area featured a good flight of a metalmark I'm interested in - call it Apodemia mormo tuolumnensis - that was among Eriogonum wrightii. I also put up a new photo of Hesperia colorado near tildeni from that area, as well as a new Cercyonis sthenele behrii that I came upon during that hike. I plan to return in mid-to-late September to try for Columbia Skippers. I've also included a brownish female Melissa Blue from a 2014 trip after realizing I only had a very blue individual on that page.

bullet pointJuly 31, 2019 - I've gone deep this summer getting to know the Santa Anita Canyon population of what should be Lycaena arota nubila. On my tenth trip to the colony site I first found June 24th, a female finally made an appearance. I also made a special trip July 28th to the Volcan Mountain Wilderness to photograph nominate arota females for eventual comparison to nubila. I feel I can learn a lot about a butterfly through reading about it, but I only get to really know it by getting out in the field to see it in its habitat. While targeting nubila, I came across a few other interesting things, such as this cool larva of an American Lady.

bullet pointJuly 17, 2019 - Took an overnight getaway to the Sherman Pass area. Alder Creek (6800') and Bald Mountain were the best places lep-wise. Meadows and roadsides were lush, but pretty much butterfly-free, which seemed strange, especially with such nice weather. I was happy to photograph the dark female Chlosyne palla I've long wanted to see. And Papilio indra phyllisae was flying at Bald Mountain and I was able to get close to the freshest one.

bullet pointJuly 13, 2019 - A Marine Blue (Leptotes marina) in my backyard garden this morning was fresh enough to photograph, so I did. I've been out and about as well and have a few things to share. One is an interesting aberrant nominate Euphydryas chaledona I happened across in one of a series of hikes to Santa Anita Canyon dedicated to looking for female nubila as mentioned below. The same location also yielded a Painted Lady caterpillar different from the one I already had here, so I added it. A hike along the McGill Trail at Mt. Piños led me to a beatiful male "Chlorina" Lupine Blue. That was a good day; earlier I saw many Veined Blues at the summit (scroll down), and that was after a stop at Lake of the Woods where Blue Coppers were flying.

bullet pointJune 26, 2019 - I was able to find a couple of male Lycaena arota nubila - the 'Cloudy' Tailed Copper - in the San Gabriels above Chantry Flats. A search specifically for females the next day didn't turn any up, though the road/trail I was on was swarming with butterflies generally. Nubila is a new addition to the site, the first new taxon in a while. By my current reckoning, that's 198 out of 256 taxa; the last few dozen are not going to be easy and I expect to be doing this for many more years, which is good. A few of the 256 (that number is somewhat arbitrary) are almost certainly extinct, so I may have to add some specimen photos at some point. I've added a nice female Bernardino Blue from the same area because I liked the wing colors so much.

bullet pointJune 19, 2019 - Decided to try the mountains on a beautiful Wednesday. Headed to Sunset Peak, mainly to see if I could get another photograph of an Indra Swallowtail. I did, but it was worn and not worth posting. But this Clemence's Blue female is typical of the beautiful blues flying here. Earlier in June I checked out a large patch of Eriogonum inflatum at a roadside pullout along Hwy. 74 in Palm Desert that I'd noticed in years past. I was happy to find not only a healthy population of Desert Metalmarks, but a Wright's Metalmark as well (the latter on Sweetbush).

bullet pointApril 22, 2019 - Cactus Spring Trail has been strangely slow for many species, but things seem to be picking up, and today was the best day there for the year (fifth visit so far). I have some catching up to do, but for now here's a Becker's White caterpillar I happened to find. That's the only new thing for this site, though I do have some nice photos among the thousand or so I've taken there lately. Behr's metalmarks are now flying (they weren't last weekend). Some butterflies (such as several whites) are having a great year, while other species are noticably absent or nearly so. For instance, among desirable species, I've seen one Sonoran Blue, no Desert Black Swallowtails, no Loki, no Small Checkered Skippers. Juba and albescens are now out. Hennei and N. californica fading fast.

bullet pointMarch 1, 2019 - Headed out to Cactus Spring Trail as things have finally begun to warm up there. The plants are generally in their winter sleep, as are most butterflies, but I was kept company by a few species. Painted Ladies are in a dispersal, so they are everywhere, but they were rivalled at times by surpringly common California Tortoiseshells. The first male Sara Orangetips have also emerged, as had a single Euphydryas chalcedona hennei. The creeks are flowing, and there is snow on the mountains; things will be hopping there in a month or so.

bullet pointJanuary 12, 2019 - Lots of rain has me encouraged that the coming year will be far better than was 2018. The few hikes I did last year were in depressingly dry landscapes, and I basically wrote the year off early on and indulged in other things. But this year will certainly be better, and I hope to make the most of it. I hope you do too.

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 (as a breeding resident). 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 currently are over 280 taxa that I've listed for our area. My goal is eventually to see and photograph them all (I have 201 of 281 as of November 2019), as well as their host plants (room for improvement there - I promise to focus on that more in years to come). Some butterflies that are very rare or only occasionally stray into our area may be 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.

* As of October, 2019, I've thoroughly revised my lists based on Ken Davenport's publication Butterflies of southern California in 2018: updating Emmel and Emmel's 1973 Butterflies of southern California. I've omitted butterflies listed in Ken's book that are outside my definition of southern California, such as those in Tulare Co. and Death Valley, as well as most non-resident strays, and (obviously) extirpated or extinct taxa. My northern boundary is the nearly-straight trio of northern county lines from San Luis Obispo to Kern and San Bernardino counties.
