Cicindelidia politula petrophila

The subspecies is distinguished from the nominate form and other related tiger beetles by its shiny black to blue-black elytra with white markings reduced or absent except at the apices, combined with a red abdomen. It is closely related to Cicindelidia punctulata (Punctured Tiger Beetle) but differs in coloration and habitat preference. The solid dark coloration with limited pale markings separates it from most other Cicindelidia species in its range.

Dry to xeric upland habitats with exposed limestone substrates, including limestone outcroppings, road banks with white limestone exposures, rocky clay areas, and scraped dirt roads along limestone hillsides. Beetles are more frequently associated with older, level exposures that have at least a small amount of vegetation; newer or steeply sloped exposures or those completely devoid of vegetation are less frequently occupied.

Northern Texas (Montague County, Johnson County, Erath County, Somervell County) and adjacent Oklahoma. The subspecies occurs primarily in Texas with populations extending into southern Oklahoma.

Adults are active in late summer and fall, typically beginning to emerge in late September. Activity continues through October.

Adults are extremely wary and difficult to approach. They exhibit rapid escape flights when disturbed, though flight distances are typically short. Under midday sun, adults engage in "sun-facing" behavior—orienting their bodies to minimize thermal exposure. They also exhibit shade-seeking behavior at the base of vegetation such as yucca plants to avoid heat. When captured, adults are adept at finding the smallest gaps between net rim and ground to escape. The "tap-and-sweep" method has been observed to be more effective for capture than "stalk-and-slap" on rough, rocky substrates.

• Cicindelidia punctulataClosely related and similar in size and general form, but differs in coloration, pattern, and habitat preference—C. punctulata occurs in more mesic situations and has different elytral markings.
• Cicindelidia politula politulaNominate subspecies with which it shares the characteristic shiny black to blue-black elytra with reduced white markings, but differs in geographic distribution and potentially in subtle morphological features.
