Crossidius suturalis melanipennis
Crossidius suturalis melanipennis is a subspecies of longhorn beetle in the family Cerambycidae. It belongs to the genus Crossidius, a group of flower-visiting beetles associated with composite plants in arid and semi-arid regions of western North America. This subspecies was described by Penrose in 1984 and is part of a complex of subspecies within C. suturalis that show geographic variation in coloration and elytral markings.
Crossidius suturalis minutivestis
A subspecies of longhorn beetle in the genus Crossidius, described by Linsley in 1957. It occurs in the San Joaquin Valley and adjacent areas of central California. Adults emerge in late summer and early fall to feed on flowers of their host plant, Isocoma acradenia var. bracteosa. The subspecies name refers to its relatively small size compared to other members of the species.
Crossidius suturalis pubescens
Crossidius suturalis pubescens is a subspecies of longhorn beetle in the family Cerambycidae, described by Linsley in 1957. It belongs to the species Crossidius suturalis, a member of the flower-visiting cerambycid genus Crossidius. The subspecies is distributed in southwestern North America, with records from Arizona and New Mexico. Field observations indicate adults are active in late summer and early autumn, where they have been found on flowers of Isocoma tenuisecta and related composite plants.
Crossidius suturalis suturalis
Crossidius suturalis suturalis is a subspecies of longhorn beetle (Cerambycidae) in the genus Crossidius. It occurs in the southwestern United States and northern Mexico. Adults have been observed on flowers of Isocoma tenuisecta (burroweed) and related Isocoma species, particularly in late summer and early fall. The subspecies is part of a complex of fall-active Crossidius beetles associated with composite host plants.
Octinodes amplicollis
Octinodes amplicollis is a species of jewel beetle in the family Buprestidae. The species has been documented in the southwestern United States, with confirmed observations in Arizona. Adults have been collected from flowers of Isocoma tenuisecta and other yellow composite flowers in late summer. The species belongs to a genus of small to medium-sized buprestid beetles.
Pyrota concinna
Pyrota concinna is a blister beetle in the family Meloidae, distributed across Central America and North America. The species has been observed visiting flowers of Isocoma pluriflora (southern goldenbush) in saltbush chaparral habitats in southeastern New Mexico. As a member of the tribe Pyrotini, it exhibits the typical blister beetle defensive chemistry and soft-bodied adult form characteristic of the family.
Schinia erosa
Schinia erosa is a noctuid moth described by Smith in 1906. It inhabits desert regions of the southwestern United States, specifically the Mojave and Sonoran Desert areas east of the Peninsular Range in southern California and south-central Arizona. The species is univoltine with adults active in late summer and fall, and exhibits a specialized larval association with Isocoma acredenia (burrobrush), a desert shrub in the Asteraceae family.
Trichodes peninsularis basalis
Trichodes peninsularis basalis is a subspecies of checkered beetle in the family Cleridae. It belongs to a genus of predatory beetles commonly found on flowers, where they feed on pollen and other flower-visiting insects. The subspecific epithet 'basalis' suggests a geographic or morphological distinction from the nominate form, though specific diagnostic features for this subspecies are not well documented in available sources.
Zonitis dunniana
Zonitis dunniana is a species of blister beetle in the family Meloidae, first described by Champion in 1891. It is found in North America, with confirmed records from the southwestern United States including Arizona and New Mexico. The species has been collected on flowers of Isocoma tenuisecta (burroweed) and Hymenothrix wislizeni, suggesting an association with blooming composites in arid habitats. It is one of approximately 15 species in the genus Zonitis occurring in the New World.
