Identification

Distinguished from similar beach-dwelling by its specific elytral maculation pattern referenced in its epithet 'latesignata' (broadly marked). Precise identification from such as Ellipsoptera hamata or E. marginata requires close examination of mandibular in males, elytral shape in females, or pronotal coloration. The species occurs in the western portion of North America, which helps separate it from eastern beach tiger beetles. Final determination typically requires reference to specialized or direct comparison with voucher specimens.

Habitat

Coastal sandy beaches and intertidal zones. Associated with open, barren sand substrates characteristic of beach environments. The specificity to western coastal regions is implied by the 'Western Beach .'

Distribution

to western North America including the continental United States and Mexico. Occurs in Central America and North America broadly, with specific concentration along Pacific coastal regions. Distribution records confirm presence in Mexico and the United States.

Seasonality

Activity patterns not documented in available sources. Most Cicindela in temperate regions exhibit spring-fall activity with summer larval development, but specific for this species requires direct observation.

Life Cycle

Typical of : with , larval, pupal, and stages. are ambush that construct vertical burrows in sandy substrates. Specific details of developmental timing, burrow depth, or size not documented for this .

Behavior

Exhibits characteristic behaviors: extremely fast running, rapid when disturbed, and visual on small . Like , likely stops periodically while running to re- vision due to speed exceeding visual processing capacity. are and highly wary, making close approach difficult. Specific behavioral observations for this not found in available sources.

Ecological Role

in sandy coastal . As a , functions as a visually hunting predator that helps regulate of small including and other ground-dwelling . Larval stages contribute to soil aeration through burrowing activity. Specific ecological studies quantifying its role not documented.

Human Relevance

Subject of interest for and naturalists studying diversity. 'Angel's Tear' suggests possible cultural or aesthetic appreciation. Like many beach-dwelling , potentially vulnerable to coastal degradation from development, recreation, and sea level change, though specific status not documented.

Ellipsoptera marginataOccurs in similar coastal and shares general appearance; requires examination of male right presence or female elytral for separation.
Cicindela repandaWidespread found in some similar open sandy ; distinguished by different elytral maculation pattern and more habitat .

Taxonomic Note

The has been treated under the Cylindera in some (as Cylindera descendens), but current sources including GBIF and NCBI maintain it in Cicindela. Authorship is sometimes cited as Mandl, 1969, but the original description is LeConte, 1851.

Etymology

The specific epithet 'latesignata' derives from Latin 'latus' (broad, wide) and 'signatus' (marked), referring to the broad or prominent elytral markings characteristic of this .
