Eleodes parowana
Blaisdell, 1925
Eleodes parowana is a of darkling beetle (Tenebrionidae) described by Blaisdell in 1925. The Eleodes, commonly known as clown beetles or stink beetles, is characterized by defensive -standing when disturbed. Species within this genus are primarily and inhabit arid and semi-arid regions of North America. E. parowana is one of numerous Eleodes species found in western North American deserts and grasslands.

Distribution
Western North America. Specific documented localities include the southwestern United States, with occurrence records from Arizona and surrounding arid regions. The epithet 'parowana' references the Parowan Valley region of southwestern Utah, suggesting a type locality in that area.
Behavior
Performs the defensive ' stand' characteristic of the Eleodes when threatened, elevating the and releasing defensive compounds from abdominal glands. This posture makes the difficult for to grasp and presents the chemical defenses effectively.
Similar Taxa
- Eleodes suturalisSimilar in general body form and coloration; both exhibit dark coloration with potential reddish-brown markings. E. suturalis is distinguished by sharply laterally carinate and broadly explanate pronotum, features that may overlap with or differ from E. parowana depending on specimen variation.
- Eleodes hispilabrisClosely related with similar size and coloration; historically confused with E. suturalis in field observations. E. hispilabris lacks the sharply carinate and explanate pronotum of E. suturalis, suggesting these characters may also help distinguish E. parowana.
- Eleodes acutaOccurs in similar and geographic regions; distinguished by pronotum shape with rounded lateral borders versus upturned borders in E. suturalis. E. acuta also averages larger in size (approximately 30 mm versus under 26 mm for E. suturalis), providing a potential comparison point for E. parowana.
More Details
Taxonomic Note
Eleodes parowana was described by Frank E. Blaisdell in 1925, a prolific describer of Tenebrionidae from western North America. The specific epithet references the Parowan Valley in Iron County, Utah, a region with significant darkling beetle diversity.
Data Limitations
This is poorly represented in public databases, with only 10 observations recorded in iNaturalist as of the knowledge cutoff. The limited observational data restricts confident statements about preference, seasonal activity, and precise distribution boundaries.
