Agonum corvus
Agonum corvus is a species of ground beetle in the subfamily Platyninae, first described by John Lawrence LeConte in 1860. The species is endemic to North America, with records from Alaska, Canada, and the contiguous United States. It is one of approximately 1,200 species in the genus Agonum, a diverse group of small to medium-sized ground beetles found primarily in the Northern Hemisphere.
Amblycorypha insolita
Big Bend Oblong-winged Katydid, Big Bend False Katydid
Amblycorypha insolita is a species of phaneropterine katydid in the family Tettigoniidae, first described by Rehn & Hebard in 1914. Known as the Big Bend oblong-winged katydid or Big Bend false katydid, this species is endemic to the southwestern United States and adjacent northeastern Mexico. It belongs to a genus renowned for exceptional camouflage and acoustic communication.
Curalium cronini
Curalium cronini is a true bug (Hemiptera: Heteroptera) described in 2008 and the sole known species of the family Curaliidae. It is endemic to North America. The family was established based on this species, representing a rare example of a monotypic family within the Cimicomorpha. Its discovery expanded the known diversity of cimicomorphan lineages.
Feniseca
North American Harvesters, Harvester
Feniseca is a monotypic genus of butterflies in the family Lycaenidae, containing a single species, Feniseca tarquinius (the harvester). This genus is notable for representing the only obligate carnivorous butterfly in North America. The larvae feed exclusively on aphids rather than plant material, a highly unusual trait among butterflies. Adults are found in wooded habitats near streams, particularly in association with alders.
Holcocera villella
Holcocera villella is a small moth in the family Blastobasidae. It has been documented in multiple U.S. states spanning both coasts. The larvae are known to feed on pine seeds, making this species a conifer seed specialist.
Hydriomena edenata
Hydriomena edenata is a geometrid moth in the family Geometridae, first described by Swett in 1909. The species is endemic to North America and includes seven recognized subspecies. It is assigned MONA/Hodges number 7232. The species belongs to the subfamily Larentiinae, a diverse group of carpet moths.
Macrosiphum gaurae
Beeblossom Aphid
Macrosiphum gaurae, commonly known as the beeblossom aphid, is an aphid species endemic to North America. It is distinguished by its unique coloration, including a brilliant rose pink form that is unique among North American aphids. The species is closely associated with evening primrose and beeblossom plants as its primary hosts. Its distribution spans from the east to west coasts of North America, though it becomes increasingly rare in the Pacific Northwest region from British Columbia to Oregon.
Pandemis lamprosana
Woodgrain Leafroller Moth
Pandemis lamprosana, known as the woodgrain leafroller moth, is a tortricid moth native to northeastern North America. Adults are active in late summer with a single annual generation. The species is recognized by its forewing pattern and moderate size. Larvae are polyphagous leaf feeders on numerous deciduous tree species.
Poultonella alboimmaculata
Poultonella alboimmaculata is a species of jumping spider in the family Salticidae, first described by Peckham & Peckham in 1883. It is endemic to the United States. As a jumping spider, it possesses the characteristic salticid eye arrangement and active hunting behavior. The specific epithet 'alboimmaculata' suggests a white or unmarked appearance, though detailed coloration descriptions are limited in available sources. The genus Poultonella is small and poorly documented, with few species.
Prionapteryx yavapai
Prionapteryx yavapai is a species of moth in the family Crambidae, first described by Kearfott in 1908. It is a member of the subfamily Crambinae, a group commonly known as grass moths. The species is known from a limited geographic range in the southwestern United States.
Stelidota octomaculata
Stelidota octomaculata is a small sap-feeding beetle in the family Nitidulidae, endemic to North America. Adults overwinter in forest litter and feed primarily on acorns, particularly damaged or germinating ones, beginning in March. Reproduction occurs in spring and early summer inside acorns both above and below ground. The species has been described as a chemical 'generalist' but behavioral 'specialist' compared to its congener S. geminata, showing reduced locomotion rates and different host-finding strategies. Laboratory studies indicate a life cycle of approximately 34 days at 22-26°C, with females producing up to 933 offspring.
Varacosa
Varacosa is a genus of wolf spiders (family Lycosidae) endemic to North America. First described in 1942 by Chamberlin & Ivie, the genus currently contains six recognized species. These spiders are ground-dwelling hunters that serve as important prey for spider wasps in the family Pompilidae, including species such as Ageniella conflicta and Priocnemis minorata.
