Identification

Belongs to the Chrysobothris femorata -group, which requires examination of character suites for reliable identification. Specific diagnostic characters for C. ignicollis relative to other members of this group are not detailed in available sources.

Habitat

Associated with Juniperus woodlands and areas where juniper occur. have been observed on freshly cut Juniperus virginiana (eastern redcedar) and on downed logs exposed to full sun.

Distribution

Western North America, with records from Oklahoma and broader distribution across the western United States. Also reported from Central America and North America generally.

Seasonality

have been observed in June in northwestern Oklahoma. Activity likely coincides with warm season conditions suitable for adult and plant availability.

Diet

Larvae feed within dead branches of Juniperus , including Juniperus virginiana. The species is a wood-borer in dead or dying juniper wood.

Host Associations

  • Juniperus virginiana - eastern redcedar; larvae reared from dead branches, observed on freshly cut wood
  • Juniperus - -level association; commonly associated with juniper throughout western North America

Life Cycle

Larvae develop within dead branches of juniper . Larval stage described in taxonomic literature, though specific developmental details are not well documented.

Behavior

are active during the day on exposed wood surfaces. Possess large, multi-faceted presumed to function in detection. When disturbed, expose brilliant metallic blue-green segments in as flash coloration. Males use pro- and mesolegs to clamp females during mating.

Ecological Role

Wood-borer in dead juniper branches; contributes to decomposition of dead wood in juniper .

Human Relevance

No significant economic pest status documented. Not associated with living shade or fruit trees unlike some .

Similar Taxa

Taxonomic History

Part of the taxonomically difficult Chrysobothris femorata -group, which was revised by Wellso and Manley (2007), doubling the number of described species in the group. Species limits rely on suites of characters rather than single diagnostic features.
