Identification

Distinguished from similar tiger beetles by elongated (upper lip), the feature giving the its name. differ in coloration: C. l. perviridis exhibits green coloration, while nominate subspecies and C. l. laurentii show more typical tiger patterning. May form intergrades with C. nebraskana (prairie long-lipped tiger beetle) in zones of contact.

Habitat

forests and climatic refugia, including high pine forests. In the Black Hills region, occurs in shortgrass prairie where it may hybridize with C. nebraskana. Associated with open ground in cooler, higher-elevation environments compared to many .

Distribution

North America, with records from Alaska, Canada, and the northern United States. Documented from the Black Hills of South Dakota and Wyoming, with extending into Nebraska Sand Hills and associated Great Plains regions.

Seasonality

Active during fall season in temperate regions, with observed in September in the northern Great Plains. Part of the spring/fall tiger fauna distinct from summer-active .

Behavior

excavate burrows for shelter, observed kicking dirt from burrow entrances in late afternoon. Larvae construct vertical burrows in suitable substrates.

Human Relevance

Subject of entomological collecting and study. Featured in regional field guides for South Dakota and Nebraska. Potential hybrid zones with C. nebraskana of interest for evolutionary studies.
