Scientific Taxonomy

  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Class: Insecta
  • Order: Lepidoptera
  • Family: Nymphalidae (brush-footed butterflies)
  • Genus: Vanessa
  • Species: cardui (Linnaeus, 1758)

It belongs to the tribe Nymphalini within the subfamily Nymphalinae.

Description

The adult Painted Lady is a medium-sized butterfly with a wingspan of approximately 2–3.5 inches (5–9 cm), typically around 5.1–7.3 cm from wing tip to wing tip.

The upperside of the wings is predominantly orange-brown to pinkish-orange, with darker bases. The forewings feature a prominent black apical (tip) area adorned with prominent white spots and a white subapical bar along the leading edge. The hindwings display a submarginal row of five small black spots, sometimes with blue scales. The wing edges are distinctly scalloped.

The underside is more subdued and mottled with patterns of black, brown, gray, and some red-orange, featuring four small submarginal eyespots on the hindwing (a key distinguishing feature from similar species like the American Lady, Vanessa virginiensis, which has two larger eyespots).

Larvae (caterpillars) are grayish-brown with darker ends, a yellow dorsal stripe, and branched spines along the back and sides. Eggs are pale green with vertical ribs.

Behavior

Painted Ladies are highly migratory and fast-flying, capable of speeds up to 25–30 mph (40–50 km/h). They are strong, directional fliers that often use favorable winds.

Males defend territories against other males. In warmer climates, mating can occur year-round, though it ceases during colder periods. Adults are avid nectar feeders, visiting a wide variety of flowers (especially taller perennials), while larvae are polyphagous herbivores feeding on over 100 plant species, with favorites including thistles (Cirsium and Carduus), mallows, and other composites.

Their most remarkable behavior is long-distance migration, which is multi-generational (no single individual completes the full round trip). In North America, they overwinter in warmer southern regions (such as Mexico or the southwestern U.S. deserts) and move northward in spring, often triggered by rainfall and host plant availability, reaching as far as Canada and occasionally Alaska. In Europe and Africa, they undertake even longer journeys, including a documented 9,000-mile (≈14,500 km) round trip from tropical Africa to northern Europe (near the Arctic Circle) and back, spanning up to six generations. Southward return migrations often occur at high altitudes (over 500 meters), making them less visible. Migration appears driven primarily by environmental cues (e.g., weather, resource availability) rather than strict genetics.

Range

Vanessa cardui is the most widely distributed butterfly species in the world, found on every continent except Antarctica and Australia (though a related species, the Australian Painted Lady, V. kershawi, occurs there).

Its range spans:

  • North America (from subarctic Canada and southeastern Alaska south through the continental U.S. and Mexico)
  • Central America
  • Europe
  • Asia
  • Africa
  • Various oceanic islands

It inhabits diverse open habitats including fields, meadows, prairies, gardens, deserts, and disturbed areas, up to elevations of around 3,900 meters in some regions. Populations fluctuate dramatically with outbreaks occurring in some years due to favorable conditions for breeding and migration.

This adaptable, highly mobile species exemplifies resilience in the face of varying climates and habitats.

Sagebrush Checkerspot (Chlosyne acastus)

The Sagebrush Checkerspot (Chlosyne acastus) is a medium-sized butterfly belonging to the brush-footed family, well-adapted to arid environments in western North America.

Scientific Taxonomy

  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Class: Insecta
  • Order: Lepidoptera
  • Family: Nymphalidae
  • Subfamily: Nymphalinae
  • Genus: Chlosyne
  • Species: Chlosyne acastus (W.H. Edwards, 1874)

Several subspecies are recognized, such as C. a. neumoegeni in parts of the southwestern range. The species is sometimes referred to as the Acastus Checkerspot in certain sources.

Description

The Sagebrush Checkerspot has a wingspan of approximately 1.5–2 inches (3.9–5.1 cm), with forewing lengths around 1.8–2.4 cm in some populations.

The upperside features a distinctive checkered pattern of black, orange-brown, and orange (paler in males, often brighter in females). The wings show black lines, smudges, and checks separating bands of pale to yellow-orange; the hindwing base may appear darker (sometimes largely black with limited orange in males). Postmedian bands can show red-orange tones in some individuals.

The underside is more contrasting, with the hindwing displaying bands of chalk-white (or pearly white spots) and brick red, outlined by black veins and edges. This ventral pattern, with more extensive white compared to similar species, aids identification.

It resembles other checkerspots (e.g., Northern Checkerspot or Rockslide Checkerspot) but is distinguished by habitat preference, lighter ventral banding, and specific wing markings.

(Images: Examples of Sagebrush Checkerspot upperside and underside views from various western U.S. locations.)

Behavior

Adults feed primarily on flower nectar from various plants in their arid habitats. Males perch in strategic locations (such as gulches or along washes) and sometimes actively patrol these areas to locate and court females. Flight is typically rapid and direct when disturbed, typical of many checkerspot species.

The flight period varies by region but generally occurs in spring to early summer (e.g., late April to late June in parts of the range like Oregon). Larvae feed on host plants in the Asteraceae family, including species such as green rabbitbrush (Chrysothamnus viscidiflorus), gray rabbitbrush (Ericameria nauseosa), desert yellow fleabane (Erigeron linearis), Mojave aster, and various asters in the genus Dieteria. The species is univoltine (one generation per year) in most areas, with adults timed to coincide with host plant and nectar availability.

Range and Habitat

The Sagebrush Checkerspot occurs across the western United States, from eastern North Dakota westward to eastern Washington, and southward to New Mexico, southern Arizona, and eastern California. It is found in states including Montana, Idaho, Oregon, Wyoming, Nevada, Utah, Colorado, and parts of the Great Basin and Southwest. Populations extend into shrub-steppe regions of southern British Columbia in some accounts, though primarily a U.S. species.

It inhabits dry, arid lowlands, typically below 5,000 feet in many areas (e.g., below 3,000 feet in parts of the Columbia and Snake River basins). Preferred habitats include sagebrush scrub, pinyon-juniper woodlands, dry gulches, washes, canyons, brushy flats, sage deserts, and hilly short-grass prairies. It thrives in shrub-steppe and semi-arid environments dominated by sagebrush and associated plants.

Overall conservation status is secure (G5 globally in many assessments), though local populations may face threats from habitat alteration in arid regions. It is not generally considered rare or imperiled across its broad range.

White-lined sphinx moth (Hyles lineata)

The white-lined sphinx moth (Hyles lineata), also commonly known as the hummingbird moth or hawk moth due to its rapid, hovering flight and nectar-feeding behavior, is a member of the family Sphingidae. It is one of the most widespread and abundant sphinx moths in the Americas.

Description of the Adult

Adult white-lined sphinx moths are large and robust, with a wingspan of 2.5–3.5 inches (6–9 cm). The forewings are predominantly dark olive-brown to gray-brown, featuring a prominent broad pale tan or white band running diagonally from the base to the tip, along with narrower white streaks along the veins (the source of the “white-lined” name). The hindwings are darker, often blackish with a bright pink or rose central band and black spots. The thorax is “furry” and robust, the abdomen conical and extending beyond the wings at rest, and the proboscis is long for reaching deep into flowers. They are strong fliers, often mistaken for hummingbirds, and are primarily crepuscular (active at dawn and dusk) but can be diurnal in some conditions.

Life Cycle Stages

Like all Lepidoptera, H. lineata undergoes complete metamorphosis with four distinct stages: egg, larva (caterpillar), pupa, and adult.

  • Egg: Females lay small, spherical, pale green to yellowish eggs singly or in small groups on the leaves or stems of host plants. Each female can produce hundreds of eggs. Incubation typically lasts about 1 week, depending on temperature.
  • Larva (Caterpillar): The caterpillars are highly variable in color and pattern (polymorphic), ranging from bright yellow-green to dark green, black, or yellowish forms, often with complex markings including black, yellow, orange, or red spots, lines, or stripes along the body. All forms feature a prominent flexible horn (caudal horn) at the rear end, typical of sphingid larvae. They grow up to 3–3.5 inches (7–9 cm) long through five instars, feeding voraciously on foliage. This stage lasts about 3–4 weeks. In high-density years, caterpillars can form mass migrations across landscapes after defoliating host plants.
  • Pupa: Mature larvae burrow 1–4 inches into the soil to form a shallow chamber and pupate. The pupa is shiny dark brown to reddish-brown, spindle-shaped, about 1.5–2 inches long, with a prominent cremaster (hook-like structure) at the rear for anchoring. The pupal stage lasts 2–3 weeks in summer or longer if overwintering (in cooler regions, pupae may diapause through winter). Emergence is triggered by temperature and moisture cues.
  • Adult: Adults emerge from the pupa, live 1–2 weeks, and focus on reproduction and nectaring. They are important pollinators of tubular flowers.

The species typically completes 2 generations per year in most of its range, with multiple generations in warmer southern areas and potentially one in cooler northern zones. In some regions, it is migratory, with populations moving northward in spring and sometimes failing to overwinter in colder areas.

Host Plants and Ecology

Larvae are extremely polyphagous, feeding on a wide variety of plants across families such as Onagraceae (e.g., evening primrose Oenothera spp.), Portulacaceae (purslane), Vitaceae (grape), Rosaceae (apple, rose), and many others including willowherb, four o’clock, elm, tomato, fuchsia, and more. Adults nectar from long-tubed flowers like honeysuckle, columbine, larkspur, salvia, and evening primrose.

Geographic Range and Habitat

Hyles lineata has one of the broadest distributions among North American sphinx moths, ranging from Central America (including parts of South America in some records) through Mexico, the entire contiguous United States, and into southern Canada. It is occasionally reported in the West Indies, and vagrants have appeared in Eurasia and Africa. It prefers open habitats such as deserts, fields, gardens, prairies, woodlands edges, suburbs, and disturbed areas, thriving in diverse climates from arid to temperate. In areas like Nevada (including Las Vegas vicinity), it is common, especially during irruption years when populations boom due to abundant wildflowers or host plants.

This species plays a key ecological role as a pollinator and herbivore, with occasional outbreaks benefiting certain cultural groups historically (e.g., as a food source). It is not considered a major pest in most contexts, though larvae can defoliate garden plants during population spikes.

Brown, Nevada – Lincoln County Ghost Town

Brown, Nevada, is a small extinct settlement and former railroad siding in Lincoln County, southern Nevada. It represents one of many minor stops along the early 20th-century rail network that supported transportation through the remote high desert.

Location and Geography

  • Coordinates: Approximately 37°36′26″N 114°07′58″W (or 37.60722°N, 114.13278°W).
  • Elevation: 5,784 feet (1,763 m).
  • It lies in the Acoma USGS map area, in a remote, arid part of Lincoln County near other ghost towns and sidings such as Acoma, Crestline, and Horseshoe Bend.

The area is typical of southeastern Nevada’s high desert: sparse vegetation, rugged terrain, and part of the broader Basin and Range province. Lincoln County itself has a long history of Native American habitation (primarily Southern Paiute), followed by 19th-century Mormon settlement attempts, mining booms (e.g., Pioche), and later railroad development.

History

The first settlement at Brown occurred in 1905, coinciding with the construction and completion of the San Pedro, Los Angeles and Salt Lake Railroad (later part of the Union Pacific’s Salt Lake Route). This line provided a direct rail connection between Salt Lake City and Los Angeles, passing through southern Nevada and spurring small sidings and support settlements.

Brown functioned primarily as a railroad siding — a non-agency stop used for passing trains, maintenance, or minor freight/passenger services rather than a developed town. Like many such places, it likely supported a handful of railroad workers, section crews, or local ranchers.

By 1941, the Federal Writers’ Project reported a population of just 10 residents, indicating it never grew beyond a tiny outpost.

Decline and Current Status

Brown faded into extinction as rail operations modernized, traffic patterns shifted, and the need for small desert sidings diminished in the mid-to-late 20th century. Today, it is classified as a ghost town, with little to no remaining structures noted in standard historical records. Its legacy is tied to the broader story of Nevada’s railroad era rather than mining, agriculture, or significant events.

Context in Lincoln County

Lincoln County (established 1866, named after Abraham Lincoln) experienced various boom-and-bust cycles driven by silver mining (Pioche in the 1870s), Mormon farming communities (e.g., Panaca), and railroads. Brown was a modest byproduct of the 1905 railroad boom, unlike more prominent Lincoln County ghost towns such as Delamar (“The Widowmaker”), Bullionville, or Fay.

Sources

Information on Brown is sparse, drawn primarily from:

  • GNIS records.
  • Nevada place-name references (e.g., Helen S. Carlson’s Nevada Place Names and the 1941 Federal Writers’ Project guide).
  • Broader Lincoln County histories focusing on railroads and ghost towns.

If you’re planning a visit, note that the site is remote with minimal (if any) visible remnants — standard precautions for Nevada backroads apply (4WD recommended, check weather/road conditions, and respect private land).

Lucky Jim Camp, Nevada

Lucky Jim Camp, sometimes referred to as Lucky Camp, was a short-lived mining camp and ghost town site in Clark County, Nevada. It is situated in El Dorado Canyon (also known as Eldorado Canyon) within the Colorado Mining District (later called the Eldorado Mining District) in the Eldorado Mountains. The site lies on the north side of the canyon, south of the Techatticup Mine, at an elevation of 2,444 feet (745 m), directly above the mouth of January Wash where it joins El Dorado Canyon.

Geographic coordinates are approximately 35°42′08″N 114°48′12″W. When established, the area was part of New Mexico Territory; it later became part of Nevada Territory and then the state of Nevada. The camp formed in a rugged desert canyon environment along the Colorado River corridor, which offered steamboat access for supplies in the 1860s.

Early History/Founding

Mining activity in El Dorado Canyon began intensifying in the early 1860s following discoveries of mineral deposits after the California Gold Rush waned. Lucky Jim Camp was founded in 1862 amid this boom. The origin of its name remains unknown.

The camp gained prominence during the American Civil War as a gathering place for miners sympathetic to the Confederate (Southern) cause. Roughly one mile up the canyon (above Huse Spring) was the rival Buster Falls camp, where Union (Northern) sympathizers congregated. The miners in the Colorado Mining District divided into these two separate communities based on their political leanings, though tensions remained largely verbal with no major hostilities reported. This split reflected national divisions even in remote desert mining areas. The broader district saw its population swell to around 300–500 workers in the early 1860s (and reportedly up to 1,500 at peak), with some individuals drawn to the lawless frontier to avoid military service elsewhere.

The camp’s location above the canyon floor also served a practical purpose: it acted as a refuge during the destructive Great Flood of 1862 (part of the widespread “Great Flood of 1861–1862” that affected the Western United States and Colorado River Basin). Lower camps near the Techatticup Mine, such as Alturas and Louisville, were destroyed or damaged, while Lucky Jim’s elevated position kept it safe. The name of nearby January Wash may commemorate the January 1862 flooding event.

Economic Activities

Lucky Jim Camp functioned as a transient support settlement for individual or small-party miners rather than a large organized town. The primary economic driver was prospecting and mining of high-grade silver chloride ores in the canyon (with gold becoming more prominent at greater depths). Ore was typically hand-sorted, sacked, and shipped—initially overland or by steamboat to San Francisco for processing—before local stamp mills were built.

No large-scale mills or smelters operated directly at Lucky Jim itself. Instead, it relied on the district’s emerging infrastructure. By late 1863, nearby El Dorado City (also called Eldorado City) was established a short distance down-canyon on the same side, featuring a stamp mill that supported ore processing. The camp’s residents likely worked claims in the surrounding Eldorado Mountains, contributing to the district’s output of silver and associated minerals. Supplies reached the area via the Colorado River, which served as a key transportation route.

Decline/Abandonment

Lucky Jim Camp was inherently temporary and declined rapidly after the Civil War. The establishment of El Dorado City in late 1863—with its stamp mill—likely supplanted the smaller camp, as mining operations consolidated. Following the end of the war, the district experienced a period of idleness and reduced activity. Many early mining camps in the canyon faded as richer surface ores were depleted and miners moved on to new strikes elsewhere in Nevada or the West.

By the mid-to-late 1860s, Lucky Jim had largely been abandoned as a distinct settlement. The Colorado Mining District continued sporadic operations into later decades (with revivals in the early 20th century at nearby Nelson), but the original 1860s camps like Lucky Jim did not persist.

Legacy/Current Status

Today, Lucky Jim Camp exists only as a historical site with no visible ruins or structures. Satellite imagery shows the area as barren, with no remaining traces of buildings, tents, or mining infrastructure. It stands as a reminder of the Civil War’s reach into Nevada’s remote mining frontiers and the boom-and-bust cycles of 1860s silver mining in the Eldorado Canyon region.

The broader Eldorado Canyon area retains historical significance through preserved sites like the Techatticup Mine (now a tourist attraction near the modern ghost town of Nelson) and connections to Colorado River steamboat navigation. Lucky Jim’s story highlights themes common to Clark County’s early mining history: political divisions, flood risks, and the transient nature of desert mining camps. The site is located on public or undeveloped land near modern-day Nelson and is accessible via backroads in the Eldorado Mountains, though it offers little for on-site exploration.
