Crossidius mojavensis

Linsley, 1955

Crossidius mojavensis is a of longhorn beetle in the Cerambycidae, described by Linsley in 1955. The species is part of a diverse western North American whose larvae develop in the roots of living shrubs in the Asteraceae family. are active in late summer and fall, when they feed on flowers of their plants. The species is found in the Mojave Desert region of California.

Habitat

Mojave Desert region of California. Associated with plants in the Asteraceae , likely including of Ericameria or related based on patterns observed in .

Distribution

United States: California (Mojave Desert region).

Seasonality

active in late summer and early fall (September), based on collection records and of related Crossidius .

Diet

feed on flowers of plants. Larvae bore through roots of living shrubs.

Host Associations

  • Ericameria nauseosa - plantInferred from related C. coralinus; direct confirmation for C. mojavensis not documented in provided sources

Life Cycle

Larvae develop as root borers in living shrubs. emerge in late summer to early fall to feed, mate, and oviposit on or near plants.

Behavior

spend their brief adult lives perched on, feeding from, or mating upon flowers of plants. At night, they bury themselves deeper among the flowers rather than leaving the plants.

Ecological Role

may contribute to pollination of plants while feeding on floral resources. Larval boring activity in living shrub roots represents a specialized herbivore-plant interaction.

Human Relevance

Subject of interest to coleopterists studying the diverse and polytopic Crossidius fauna of western North America. Collected for scientific study and personal collections.

More Details

Taxonomic Context

Part of a exhibiting extreme polytopism (geographic variation), with numerous described and locally distinctive across the Great Basin and adjacent regions. The discontinuous distribution of plants across broken western topography has contributed to this variability.
