Cicindelidia trifasciata ascendens

Distinguished from co-occurring salt marsh tiger beetles by the combination of dark brown dorsal coloration and the characteristic thin, sinuous, S-shaped middle elytral maculation. Habroscelimorpha severa, which shares the saline habitat, has a shiny green surface with maculations reduced to small spots at the middle and rear of the elytra. Eunota togata togata has more extensive pale markings. The dark brown coloration separates it from the typically brighter green or brown species of Ellipsoptera.

Dark brown dorsal coloration overall. Elytra bear a thin, sinuous, S-shaped middle maculation that is diagnostic for the species. The dark coloration contrasts with the pale, wavy elytral marking. Body form typical of tiger beetles with large, prominent compound eyes and long, slender legs adapted for rapid running.

Coastal salt marshes and tidal wetlands with moist, saline substrates. Found on areas of the flats close to the water's edge, particularly on barren, wet, muddy exposures. The habitat is characterized by saline conditions and open, sparsely vegetated mudflats.

Gulf Coast of North America from Texas through Florida. Documented in southern Texas, coastal Florida (including Dixie County), and as a rare vagrant in southern Missouri. GBIF records also indicate presence in Belize, Costa Rica, Cuba, El Salvador, and Guatemala, though these may represent the broader species complex rather than this subspecies specifically.

Active during summer months; August observations indicate peak season activity in Florida. The species remains active during hot afternoon conditions.

Extremely active and flighty, especially during hot conditions. Difficult to approach closely for observation or photography. Runs rapidly on wet, muddy substrates. Activity patterns suggest diurnal habits with continued activity into late afternoon.

Sought after by tiger beetle enthusiasts and collectors; the coastal salt marsh habitat at the 'Road to Nowhere' in Dixie County, Florida has achieved legendary status among collectors for high species diversity including this subspecies.

• Habroscelimorpha severaShares saline coastal habitat but distinguished by shiny green surface with maculations reduced to small spots at middle and rear of elytra, versus dark brown with sinuous S-shaped middle band
• Eunota togata togataCo-occurs in salt marsh habitats but has more extensive pale elytral markings and different overall coloration
• Ellipsoptera hamata lacerataFound on Gulf beaches nearby but has diffuse middle maculation and different habitat preference
