Cicindela decemnotata montevolans
Knisley & Kippenhan, 2012
Cicindela decemnotata montevolans is a of the Badlands Tiger Beetle described in 2012 based on morphological and molecular evidence. It represents one of four subspecific entities recognized within C. decemnotata, a that has undergone rapid phylogenetic radiation following glacial recession in the past 10,000 years. The subspecies occupies montane or high-elevation within the broader range of the species, which extends across the Rocky Mountains from the northwestern Great Plains and northern Great Basin north to Yukon.

Identification
The sharply angled media band of the white elytral marking that does not reach the elytral edge is diagnostic for C. decemnotata as a whole. Within the , C. d. montevolans is distinguished from other by morphological characters supported by molecular evidence, associated with montane . The including C. decemnotata, C. limbalis, C. splendida, C. denverensis, C. sexguttata, C. patruela, and C. denikei share green coloration with variable red markings, but C. decemnotata is the westernmost member of this group.
Habitat
Occupies montane or high-elevation areas within the broader range of the . The parent species C. decemnotata is associated with alkaline flats, sandy ridges, and open sagebrush landscapes in western . Specific habitat preferences for this relate to its montane distribution.
Distribution
Montane areas within the Rocky Mountains region; the broader range extends from the northwestern Great Plains and northern Great Basin north to Yukon. Distribution records indicate presence in Alaska, Canada, and the USA.
Seasonality
are active in fall, with observations from September documented. Activity patterns likely follow typical tiger with peak activity in warm, sunny conditions.
Life Cycle
Larval stages occur in burrows in sandy or alkaline soils. Developmental timing follows the typical tiger pattern with larval and in favorable seasons.
Behavior
are visual that actively hunt on the ground surface. When approached, individuals may initially appear calm but can become skittish and rapidly flee using their running ability. The exhibits thermoregulatory including stilting (elevating the body on long legs) when photographed in natural settings, though confined individuals often adopt a 'hunkered down' posture.
Ecological Role
Predatory tiger functioning as a visual hunter of small arthropods in open, sandy, and alkaline . The rapid phylogenetic radiation of this following glacial recession represents a notable case of post-glacial and diversification in the Cicindelinae.
Human Relevance
Subject of taxonomic research combining morphological and molecular approaches to resolve subspecific variation. The formal recognition of including montevolans provides entities for conservation policy decisions and facilitates discussion of polytopic variation within the .

More Details
Taxonomic History
Recognized as a new in 2012 by Knisley, Woodcock & Kippenhan based on integrated morphological and mitochondrial analysis. The study supported recognition of four subspecific entities within C. decemnotata, three of which were described as new.
Evolutionary Significance
Molecular analyses indicate relatively low genetic divergence combined with marked morphological differences, suggesting recent and rapid radiation following glacial recession within approximately the past 10,000 years. This pattern parallels that observed in the Cicindela maritima group occupying similar ranges.
Nomenclature
The subspecific epithet 'montevolans' refers to the montane or mountain-dwelling distribution of this form, distinguishing it from other occupying different elevational zones.
