Armalia texana
Armalia texana is a species of darkling beetle in the family Tenebrionidae, described by LeConte in 1866. The genus Armalia is a small group within this large family, and A. texana appears to be primarily associated with arid and semi-arid regions of the southwestern United States and adjacent Mexico. Like other tenebrionids, this species is likely nocturnal and adapted to xeric conditions. The specific epithet "texana" indicates the type locality or primary association with Texas.
Calosoma angulatum
angulate caterpillar hunter
Calosoma angulatum, commonly known as the angulate caterpillar hunter, is a large ground beetle in the family Carabidae. First described by Chevrolat in 1834, this species ranges from the southwestern United States through Central America into northern South America. It inhabits premontane moist forests and oak-savannah ecosystems. Adults are known to prey on Spodoptera frugiperda (fall armyworm), indicating a role as a predator of agricultural pest caterpillars.
Chrysanthrax juncturus
Chrysanthrax juncturus is a bee fly species in the family Bombyliidae, distributed in the southwestern United States and Mexico. As a member of this diverse fly family, it likely shares the characteristic bee-mimicking appearance and parasitic larval lifestyle typical of many bombyliids, though specific details for this species remain poorly documented.
Ebo
running crab spider
Ebo is a genus of running crab spiders in the family Philodromidae, first described by German arachnologist Eugen von Keyserling in 1884. These small spiders are distinguished by their extremely elongated second pair of legs, which are at least twice the length of the other legs. The genus formerly contained 22 North American species, but recent taxonomic revisions reassigned most to the genus Titanebo, leaving seven species in Ebo sensu stricto. The genus has a broad distribution including the United States, Canada, Mexico, Argentina, India, and Russia, with highest diversity in the southwestern United States.
Leptoypha drakei
Leptoypha drakei is a species of lace bug in the family Tingidae, first described by Mc Atee in 1919. Like other tingids, it possesses a distinctive reticulated, lace-like pronotum and hemelytra. The species is known from the southwestern United States and adjacent Mexico.
Ministrymon clytie
Clytie hairstreak, Clytie Ministreak
Ministrymon clytie, commonly known as the Clytie hairstreak or Clytie Ministreak, is a small butterfly in the family Lycaenidae. First described by William Henry Edwards in 1877, this species ranges from the southwestern United States through Mexico to Central America. It inhabits tropical forest openings and subtropical thorn forests. The larvae feed on Pithecellobium species.
Narnia inornata
cactus bug
Narnia inornata is a leaf-footed bug (family Coreidae) distributed across the southwestern United States and Mexico. It is strongly associated with cactus habitats, where it feeds on fruit and stem joints of prickly pear (Opuntia) and cholla (Cylindropuntia). The species is relatively small and quick-moving, making it difficult to photograph in the field. It is one of several Narnia species specialized for life in arid, cactus-dominated ecosystems.
Paraidemona species-c
Paraidemona species-c is a grasshopper in the family Acrididae, documented as a recorded host of the sphecid wasp Prionyx thomae. The genus Paraidemona belongs to the band-winged grasshopper group, characterized by patterned hindwings. This species has been observed in the southwestern United States.
Schinia bicuspida
Schinia bicuspida is a small noctuid moth with a wingspan of approximately 23 mm. It occurs across the south-central and southwestern United States. The larvae feed on specific host plants in the aster family, including Isocoma drummondii and Machaeranthera annua. Like other members of the genus Schinia, adults are likely associated with the flowers of their larval host plants.
Stenaspis solitaria
Stenaspis solitaria is a longhorn beetle species in the family Cerambycidae, described by Thomas Say in 1824. It occurs in the southwestern United States and Mexico, where it has been collected from various woody hosts including Acacia species and Baccharis sarothroides. Field observations indicate adults are active during summer months, particularly July and August, and are often found by beating vegetation or sweeping flowering plants.
