Euphydryas anicia wecoeut is a subspecies of checkerspot butterfly in the family Nymphalidae. It belongs to a complex of Euphydryas checkerspots found in western North America. The subspecies was described in 2006 by M. Fisher, Spomer, and Scott. Like other members of the genus, it is associated with specific host plants for larval development. The broader species Euphydryas anicia has been the subject of conservation concern, with related subspecies proposed for federal listing.
Euphydryas chalcedona a paradoxa
Euphydryas chalcedona a paradoxa is a subspecies of the variable checkerspot butterfly, a member of the Nymphalidae family. The species Euphydryas chalcedona occurs in western North America, with subspecies showing geographic variation in appearance and distribution. Like other checkerspots, this taxon is associated with specific host plant relationships and has been subject to conservation concern due to habitat pressures. The subspecies epithet 'a paradoxa' suggests anomalous or unusual characteristics compared to the nominate form.
Euphydryas chalcedona klotsi
Euphydryas chalcedona klotsi is a subspecies of the variable checkerspot butterfly described by dos Passos in 1938. It belongs to the family Nymphalidae and is currently treated as a synonym of Occidryas chalcedona in some taxonomic databases, reflecting ongoing taxonomic revision in the Euphydryas genus complex. The broader species Euphydryas chalcedona is known to exhibit significant population declines in western North America, with climate change identified as a major contributing factor.
Eupompha elegans
Elegant Blister Beetle
Eupompha elegans is a blister beetle in the family Meloidae, distributed across Central America and North America. The species comprises two recognized subspecies: Eupompha elegans elegans and Eupompha elegans perpulchra. Adults are known to feed on floral resources, with documented host associations including Chaenactis fremontii (Asteraceae) and Eschscholzia minutiflora (Papaveraceae) for the perpulchra subspecies. Like other meloid beetles, it produces cantharidin, a defensive compound.

Adults have been documented feeding on flowers of specific host plants in the Polemoniaceae family, including Eriastrum densifolium, Eriastrum sapphirinum, and Gilia tenuiflora. Mating behavior occurs on host flowers. The subspecies is represented by 930 specimens in the Entomology Research Museum holdings, indicating it is relatively well-collected and presumably common within its range.
Eusattus dubius arizonensis
A darkling beetle subspecies described from Arizona in 1984. Part of the diverse Eusattus genus within the Tenebrionidae family, this taxon represents one of many cryptic or poorly documented beetle subspecies in the North American aridlands. The species Eusattus dubius itself was described by Casey in 1890. Very few observations exist in public databases, suggesting either genuine rarity or undercollection due to its cryptic habits.
Euschistus tristigmus luridus
Euschistus tristigmus luridus is a subspecies of the brown stink bug Euschistus tristigmus, first described by Dallas in 1851. A 2022 taxonomic revision corroborated Uhler's 1861 proposal to synonymize this subspecies under Euschistus tristigmus tristigmus, based on morphological overlap between subspecies and their sympatric distribution. The taxon was included in a study formalizing the ictericus group within the subgenus Euschistus (Euschistus), though E. tristigmus itself was excluded from this group.

It belongs to the genus Exochus, a group of koinobiont parasitoid wasps that attack concealed lepidopteran larvae. The subspecies designation suggests geographic or morphological differentiation from the nominate form E. nigripalpis nigripalpis. Records indicate presence in Canada, Denmark, and Norway.
Galgupha nitiduloides
ebony bug
Galgupha nitiduloides is a species of ebony bug in the family Thyreocoridae, a group of true bugs characterized by their compact, often shiny black bodies. The species occurs across Central America and North America, with three recognized subspecies showing geographic variation. As a member of the shield bug complex, it possesses the typical pentatomoid body plan but with the reduced scutellum and distinctive form characteristic of ebony bugs. Documentation of this species remains limited, with few observational records available.
Graphocephala hieroglyphica atra
Graphocephala hieroglyphica atra is a subspecies of leafhopper in the family Cicadellidae. Like other members of the genus Graphocephala, it possesses brochosomes—protein-lipid nanoparticles produced in the Malpighian tubules and applied to the body surface using comb-like spines on the hind legs. These brochosomes render the cuticle superhydrophobic and anti-reflective. The subspecies designation 'atra' indicates a dark or black coloration variant of the species G. hieroglyphica. Leafhoppers in this genus are plant feeders that use piercing-sucking mouthparts to extract xylem fluids.

Limenitis archippus floridensis
Florida Viceroy
Limenitis archippus floridensis, commonly known as the Florida Viceroy, is a subspecies of the Viceroy butterfly found in the southeastern United States. This butterfly is renowned for its mimicry of the Monarch butterfly (Danaus plexippus), though recent research indicates it is also unpalatable to predators, making this Müllerian rather than Batesian mimicry. The Florida subspecies is notably larger and darker than typical Viceroys, adaptations that allow it to mimic the Queen butterfly (Danaus gilippus) which replaces the Monarch as the model species in Florida. Males are highly territorial, patrolling areas and perching frequently—a behavior not observed in Monarchs.
Limenitis archippus watsoni
Watson's Gulf Coast Viceroy
Limenitis archippus watsoni is a subspecies of the viceroy butterfly found in central North America. It is part of the well-known mimicry complex with the monarch butterfly, though recent research suggests viceroys may also be unpalatable to predators. This subspecies is distinguished from other viceroy populations by geographic range and subtle morphological differences.
Liodessus
Liodessus is a genus of small diving beetles in the family Dytiscidae, tribe Bidessini. Species occur across the Americas from North America through the Andes to southern South America, with notable diversity in high-altitude wetlands and páramo ecosystems. Many species inhabit shallow, exposed pools and temporary water bodies, showing phenotypic plasticity in body form correlated with habitat permanence. The genus contains numerous species, with several new species described from the high Andes of Peru and Colombia in recent years. Taxonomic resolution relies heavily on male genital morphology.
