This tale begins on the south rim of the Grand Canyon, towards the end of our Arizona holiday. Neither my son, Chuck, nor Sandra had been to the Grand Canyon. As we were in Flagstaff, a mere two hours away, this was a must. Like so many national parks, a geologic feature, e.g. Mt. Rainier, Crater Lake or the Grand Canyon, provide the major draw for one's visit. However, National Parks, perhaps more than any other federal endeavor, protect natural plants. I didn't appreciate the importance of this until I started watching butterflies.

So, on a sunny morning in mid-April, we arrived at Mather Point, a short walk from the parking lot that services Grand Canyon Village. This is one of the iconic looks at the canyon, certainly the easiest at the beginning of your park experience.
There were a number of Turkey Vultures soaring just overhead, which I was eager to turn into California Condors. As far as I know, there were no actual condors, which have been reintroduced into Grand Canyon to the tune of 98 individuals living in the wild in the park. What a success story!
And there were a number of Rock Squirrels, deemed the most dangerous animal in the park, due to the number of finger bites they inflict on well-intentioned tourists. I was satisfied with a photograph of a squirrel, and after filling our eyes with the splendor of the rocks, we headed out.
Soon we achieved the Grand View canyon look out. Indeed, like several other stops along the way, the views were grand. Here there were a few more trees, bushes and good old dirt, upon which, for no reason that is obvious to me, we did find many a butterfly. In the area, we all spotted a medium sized yellow butterfly winging through among the trees.

The three of us gave chase and we were rewarded with a good look, 5 seconds or so, through the close focus binoculars of less than ten feet.
This was a swallowtail, with a wing pattern much like the Anise we see in the PNW. This is to say, that opposed to the stripes that one would see on tiger Swallowtails, he had a black cell leading his front wings.
At this point I repaired to my friend Gemini. All the AI programs are up front about the possibility of bad information. Although they are basically programmed to engage you in conversation, I have been mostly impressed that they give better information than a plain old Google search. Gemini suggested that this was a Baird's swallowtail. Later, comparing iNaturalist posts with Google images, it was easy to see that this was a Desert Black Swallowtail, a well-documented resident, per iNaturalist, of the south rim of the Grand Canyon.

We made our way south, stopping at Duck Rock and Moran Point to look at the rocks. A bit further we stopped at a parking area that gave access to dry woodlands with no canyon access. Sandra stayed in the car, the south rim is higher than Mexico City, and she needed to take it easy. We strolled through live oaks and Ponderosa Pines and found two butterflies close together in some weeds. Such is my botanical expertise that I can't be more specific.
One of the butterflies was a Painted Lady. The other might have been a Variegated Fritillary. The quality of our look was insufficient to make an identification. It had spots, it was dust brown and iNaturalist puts this species on the south rim.
We walked up hill to the car park, and there, right next to our car, we found a duskywing, It was fairly still and Charles and I both got pictures. He has the better camera and the picture you see is the one he took.
Gemini thought this was a Funereal Duskywing. Certainly, all duskywings are well dressed for a postmortem service. This individual has a prominent white band on the hind wing, a feature of the funereal. iNaturalist only lists the Rocky Mountain Duskywing on the south rim, so I submitted this observation to them. The panel from Arthropods of the Southwest responded with an identification: Rocky Mountain Duskywing,
Erynnis telemachus. What with all the creepy hinged animals in that part of the country, from scorpions to tarantulas, the guys at Arthropods of the Southwest must have found this dingy skipper pretty tame fare.

As an aside, it was fun to see my son's enthusiasm for butterfly catching, photographing, and identification once we were engaged in the enterprise. In addition to a picture of the dark hued skipper, I'm showing you a picture that Sandra nabbed of Charles and I from the front seat as we crested the hill in hot pursuit.
On to Boise
Before we could return home, we flew from Phoenix to Boise to see our grandchildren and their parents. Like Flagstaff, Boise was cold and windy. This is not perfect weather for butterflies or aging lepidopterists. We were privileged to watch one kid football game, in which our younger grandson scored two of his team's three touchdowns and four baseball games in less than 48 hours.

Once you get away from the Boise River and its trickling tributaries, the area is basically a desert. This is good for butterflies, if you have time to seek out that bit of water. With the sports, we were reduced to looking for butterflies on the less groomed edges of large parks and in a suburban back yard that backed on to a bleak desert.
At one park I found blooming a member of the mustard family, supposedly good for Orangetip Butterflies, which were not present, perhaps due to the cold wind. It took a bit of hunting, during the innings when my player was neither batting nor in the field, to find and cross Tenmile Creek that bordered the large park with its multiple playing fields. Here, on the other side of a dirt bridge that covered a culvert, I found plain old dirt, which we know is a good butterfly finding substrate and the aforementioned mustard.
Being a poor botanist, I was gratified when Google lens reported that I had identified
Chorispora tenella. This plant is commonly known as Russian Blue Mustard and it is, as the name suggests, introduced from Asia. However, as us Hawaiians (or whatever the hell we haolies are) know, even a non-native plant can serve as a host if it has the mustard. Take Crown Milkweed, which has the alkaloids to satisfy the Pacific race of the Monarch.

| Nothing worse than pitching in front of a cold defense. |
Our friends at Genesis confirm that there are four species of the genus Anthocharis in Russia and Chia, and they use Chorispora tenella as a host plant. You can only imagine how proud I was when Genesi said, "It is fascinating that you connected these two! Russian Blue Mustard is indeed the host plant for butterflies in the genus Anthocharis in their native ranges across Russia and Central Asia." Next thing you know, I will be visited by an attractive young chatbot, feigning interest in butterflies while convincing me that I would make a delightful assassin.
In this case, the Russian Blue Mustard, with its delicate lilac colored flowers, has the oils essential to satisfy an orange spot caterpillar. Not only that, but it blooms in the early spring when these butterflies are active. The problem was that despite my excellent sleuthing and botanizing, the little white butterflies with their charming orange spots were not present on that cold, windy afternoon. Not only that, but Colsen was getting hit hard and at the end of a double header his defense sucked. You may ask, "Who in God's green earth makes ten-year-olds play a double header?" Any normal person might also wonder at a septuagenarian looking for butterflies on a cold day in the desert.

The good news is that if you are reading this blog, you most likely aren't normal. Lucky for you, that is not necessarily a bad thing.
We ate late and were back for one more game the following afternoon. Reid's team trounced the opposition, and the game was called on a mercy rule, in time for us to make it to the suburban back yard in time for some butterflies. There weren't a lot of them, but one landed on a large stone at the corner of their lanai (which has a killer view if you like bleak desert) and I was able to identify it with bare eyes as a Painted Lady. Of course, there are three species of ladies, the painted being by far the most common and it requires more than bare eyes to make an accurate identification.
Two months ago, James, the father of the young sportsmen, had texted us a picture of a fox on the other side of his back fence. That night, after dinner, a small fox appeared. James speculates that they have a den on the steep slope that drops from their back yard. He was overjoyed that I got to see one. This fox wasn't large and it didn't look particularly red to me, so I wondered if it might be a Kit Fox, which is an animal of the desert. James picture, seemingly of a different animal in the same family, confirms that these are red foxes, Vulpes vulpes.

Finally, it was time to come home to Vancouver. It was nice when we arrived, but by the next morning, we were suffering with cold rain that persisted for two days. On that first day, my daughter in law texted me with the picture you see here. The day we left Eagle was festooned with Painted Ladies. Being a veritable Nimrod, Tara got hers.
Two days ago, the weather broke, and by Saturday we were enjoying a sunny day and a high temperature over 60.
Sandra and I drove east on the 14 to Steigerwald National Wildlife Refuge. The first warm day , and a Saturday to boot, had attracted a full parking lot of visitors. Virtually all of them had made the half mile trek along the dike into the heart of the refuge. We, on the other hand, readied our nets and began patrolling the weedy acres adjacent to the car park.
A stand of blooming lupine didn't yield anything, so we began working the weeds. Soon a brownish butterfly flew and I chased him. Landing every now and then, he kept ten feet ahead of me and I never got a good look. He flew off, but in a few minutes we spotted another, this lime on the gravel path. I got close enough to identify him as a lady, but I was unable to net him.
Finally, Sandra called out that she had one secure in her net. What a woman!

We took him home, refrigerated him and took some pictures. We were really hoping for a look at the dorsal back wing, with the diagnostic lager blue spots. We got the ventral wings that you see here, but despite trying the wet sink trick we pioneered in Prescott, we could not get a good photo of the dorsal hind wing. I took him out to the rhododendron in front where a bit of persuasion yielded me a quick look at four dark blue spots. Painted Lady confirmed.
This was a good start to the 2026 butterfly season. We got a few life butterflies in Arizona and saw, in just over a week, Painted Ladies at 7000 feet at the Grand Canyon, at 3500 feet in Eagle Idaho and at a few hundred feet west of the Cascades in Washougal.
Lucky for me, I'm the sort of guy who likes ladies.
