NABOKOV'S SATYR

Nabokov’s Satyr, Ramsey Canyon, AZ (Mike Watson)

Researching range-restricted, spring-flying butterflies that I might see on my recent California & Arizona Specialities Birdquest tour I was struck by the fact that most of the special butterflies fly in the Arizona ‘second spring’ monsoon season from July to September. However, there are a few that could be seen in the actual springtime of my visit, in early May. One of these caught my eye, Nabokov’s Satyr. Not only as it carries a famous name, but I noted that it belonged to a new butterfly genus for me Cyllopsis, the ‘gemmed satyrs’. Essentially subtle browns, with jewel-like studs embedded on their hindwing borders, like blues. What a wonderful combination! There are more than 30 members of this Neotropical genus, three of which occur in the southern United States: Gemmed Satyr Cyllopsis gemma; Canyonland Satyr C. pertepida and Nabokov’s Satyr C. pyracmon. My pal Craig Robson, who spends part of the year in Southeast Arizona, said the latter was ‘easy anywhere in the mountains on trails/in shade’ and looking at the number of INaturalist.org sightings I thought I should have no trouble in catching up with it in early May. With many pairs of eyes in my group I mentioned that we should be on the lookout for any small brown butterflies and sure enough on our first morning in the Sky Island canyons, at the lovely Madera Canyon near Green Valley, while returning from a successful hike in search of Coppery-tailed Trogon, sharp-eyed Richard spotted one. It was a Nabokov’s, albeit a worn individual with a torn hindwing. Very exciting nevertheless! Thanks Richard! After alighting on a stone, it moved off quickly uphill and into dense scrub and out of reach. Moving with surprising speed at ground level, it skipped through the bases of thorn bushes, a most annoying habit of this species I was to discover in the coming days.

Interest in butterflies on our birding tours is very limited, so my opportunities are therefore compressed into a few minutes here and there. The next canyon bottom we visited, the lovely Miller Canyon also produced Nabokov’s Satyr at each stop, but in the heat of the midday they were completely restless and rarely paused for more than a few seconds on their ramblings through the shady understorey of the evergreen oak and Alligator Juniper woodland, when they would angle their wings perpendicular to the shafts of sunlight reaching the leaf litter, in the manner of a grayling back home. This did not allow me enough time to get in position for a photo before they were off again. Goodness me, it was hard work following these pesky creatures round and round a small patch of woodland, before ultimately losing contact, as they made off through the bushes. All too soon, my group returned from a hummingbird feeder sojourn with my co-leaders and that was that.

They were indeed in each canyon and, finally, it was in Ramsey Canyon, the most famous of all the birding spots in the Huachuca Mountains, that I could finally spend some quality macro time with the satyrs, significantly late in the afternoon when they settled down to visit wet patches of ground in the watercourses and directly under the hummingbird feeders! Most were quite worn by this stage in their flight season and it was more difficult to read their undersides to separate them from the very similar Canyonland Satyr (which is usually found further uphill rather than in the valley bottom) but they were very approachable now. A very satisfying experience to go alongside the other avian treasures of these precious habitats. How many takers for ‘I’ve got a settled Nabokov’s Satyr here’? None at all. We are so few.

The butterfly is named after the Russian/American author Vladimir Nabokov (1899 – 1977), a fascinating character whose most famous work is the 1955 novel Lolita. It is hailed one of the greatest literary works of the 20th century but the subject is such a hot potato now! He was born of Russian nobility but moved gradually westwards, fleeing the Russian Revolution and then Hitler’s Germany, before settling in the United States and gaining citizenship in 1945. Nabokov was a true polymath and as well as an acclaimed author, he was also an accomplished entomologist and has several butterfly and moth species named after both him and his literary works! He wrote in three languages; Russian, English and French, gave boxing lessons and composed chess problems. He lectured at Cornell, (where one of his students was US Supreme Court Justice Ruth Bader Ginsberg). He was mostly concerned with studying blue butterflies and genetic research later supported his hypothesis that the Polyommatus blues came to the Americas over the Bering Strait in five waves, eventually reaching Chile. I was fascinated to read that Nabokov did not learn to drive, he got his wife Véra to drive him around in search of butterflies and in 1967, he commented ‘The pleasures and rewards of literary inspiration are nothing beside the rapture of discovering a new organ under the microscope or an undescribed species on a mountainside in Iran or Peru. It is not improbable that had there been no revolution in Russia, I would have devoted myself entirely to lepidopterology and never written any novels at all.’ Interestingly ‘his’ satyr was first described in 1867 and the use of his name stems from the description of its subspecies named nabokovi in his honour by Lee D. Miller in 1974, from none other than Ramsey Canyon, Arizona (!). The epithet Nabokov’s was later adopted as the common name for the larger species. I hope it does not get cancelled, as is the current Cornell habit with birds. We would surely end up with some hopeless anodyne alternative.

f.helice!

Clouded Yellow | Colias crocea f.helice - Longridge Fell 17 August 2025 (Mike Watson)

f.helice! How could I possibly follow yesterday’s butterflies? This is how! The first Clouded Yellow near the junction was a white one of the form helice this morning. I had thought why not try and find a helice, as I saw one had been seen in the northeast yesterday? But almost immediately I heard from John Wright that Pete Kinsella had already seen one the day before on Longridge Fell, presumably after we left, so I was hoping it would still be around. I didn’t imagine it would be so easy to find though. Sadly it did not hang around, it disappeared into the plantation to the north at 0955 and was not seen again, despite much searching. There were still at least four other Clouded Yellows present today but there were generally fewer butterflies. However, it was impressive nevertheless with tens of Painted Ladies on the Longridge Riviera. Another fabulous local butterfly watching day!

The only species missing today was Small White. Joined by Phil Larkin and Lee Parnell, my old Ribchester pals, we saw some interesting other things, included a Small Copper probably of an aberration that we haven’t managed to pigeonhole yet as well as the Furry Peat Hoverfly | Sericomyia superbiens (briefly on the same knapweed). There was also a male Black Darter | Sympetrum danae of note, the first I have seen here. There were also a few Tree Pipits around today and other hoverflies included Common Batman Fly | Myathropa florea and Yellow-barred Pond Fly | Sericomyia silentis, two species I am familar with from Grindleton Fell, a few miles to the east.

HILLTOPPING!

Clouded Yellow | Colias crocea - Longridge Fell - 16 August 2025 (Mike Watson)

HILLTOPPING! I knew this was a thing from the continent, associated with mate location and wondered if it might be connected to migration too. Well, I am pretty sure it is. My lunchtime walks up Longridge Fell have regularly included migrant nymphalids like Painted Ladies and whites moving uphill along the forestry tracks but today was something really special. I was hoping to find a Clouded Yellow, with so many reported moving north through the UK at the moment and a late report of one on the fell on 12 August but I wasn’t expecting it to be quite as good as it was on the top of the fell today. The morning started slowly at Salthills Quarry - only two Red Admirals and then at Barrow Lower Lodge - a Small Copper of note, so I wasn’t very hopeful. Walking up the Seven Bends at Longridge Fell was quieter than usual but maybe things had not got going yet as it had been quite cloudy so far. A faded Wall Brown livened things up and then BAM! Clouded Yellow!

I like them because they are very easy to spot! There’s no other butterfly that bright orange-yellow colour in our landscape. It was very mobile flying up and down a very flowery ride between young forestry plantations, the borders of the sandy track rammed with knapweed. After a while following it back and forth it landed a few times, FAB-U-LOUS! The crazy big green eyes, pink legs and the figure of eight on its hindwing! Ooh! There’s another! There were three more and when I retraced my steps back to the spot of the first sighting with Ribchester pal Phil Larkin, we had three together, so that’s six in total at least!

There were so many other butterflies along the quiet forestry tracks today, at one point I counted 50 nymphalids on a 20m stretch of knapweed alone. Lots of Red Admirals and Small Tortoiseshell and smaller numbers of Painted Ladies, Large and Small Whites. There were also residents of the Fell: a single Comma, Green-veined Whites, two Small Coppers, Common Blue, a single Meadow Brown and Speckled Wood and three more lovely Wall Browns! Easily my most exciting day butterflying in East Lancs. 10 species is my benchmark for a good walk and I think 14 must be my highest so far. There were some other good insects today. My first Migrant Hawker of the year was at Barrow Lower Lodge, where there were still at least four Small Red-eyed Damselflies, a late Broad-bodied Chaser, as well as three Brown Hawkers, a couple of Emperors and lots of Common Blue Damselflies. On the fell we saw several Southern Hawkers, including some lovely lime-green females, a Common Darter and a couple of Common Hawkers. However, the best sighting was probably one of the last, Furry Peat Hoverfly | Sericomyia superbiens - an uncommon late-flying carder bee mimic. Thanks to Pete Kinsella for pointing this out to us. What a day today was!

LAST OF THE SUMMER BUTTERFLIES

Brown Hairstreak | Thecla betulae (female), Arnside & Silverdale AONB (Mike Watson)

LAST OF THE SUMMER BUTTERFLIES. The last two single brood butterfly species to emerge are usually Scotch Argus Erebia aethiops and Brown Hairstreak Thecla betulae. The former is easy enough to see, particularly at its mega colony of Smardale Gill, but Brown Hairstreak is not nearly so. It was re-introduced to the Morecambe Bay limestone in, or prior to, 2011 having gone extinct in the Arnside/Silverdale area in the 1930s. This was a private release and I have no idea if it has been supplemented since but it can now be seen with some regularity at several spots here. Just like in its southern haunts, it is particularly fond of Hemp Agrimony nectar, where it can be ridiculously tame.

Scotch Argus Erebia aethiops had already been on the wing for a couple of weeks at Smardale Gill ,where, unlike the suggestions online, it is not in the floral verges of the disused railway line, rather on the steep unimproved alkaline grassland opposite the viaduct itself. It was abundant, I saw around 50 walking across the grassy slope but many were quite worn. It is a 2.5km walk each way from Smardale Hall and I will remember that the northwest facing slope is in shade until late morning. There was not much else here though, just a few tatty Meadow Browns Maniola jurtina and Gatekeepers Pyronia tithonus.

The impressive viaduct has 14 arches and carried the South Durham and Lancashire Union Railway for 101 years until the line’s closure in 1962, one year before the Beeching Report. The trains that crossed it transported coal to the steelworks in Barrow but when they closed there was no longer any need for this route.
