Identification

Distinguished from the nominate C. l. lengi by a distinct coppery underside to the . Differs from the co-occurring and morphologically similar C. formosa (big sand ) by a slightly narrower body form, longer and narrower , and most notably by the obliquely straight (rather than "C"-shaped) marking on the . The subspecies C. l. jordai in the southwestern range has broadly coalesced elytral maculations, which C. l. versuta lacks.

Habitat

Dry sand including sand blowouts, dune margins, sand flats, and sandy roadsides. In the northern part of its range, inhabits coniferous forest along sandy roadsides. Has been observed on sand bars along rivers. Appears to favor very fine-grained sand over coarser-grained sands typical of some sandhill regions.

Distribution

Northern Great Plains of North America, including parts of Canada and the northern United States. Range extends north of Nebraska and Colorado, where it replaces the nominate .

Seasonality

active in late summer; observations concentrated in September. present in substrate during other seasons.

Life Cycle

Larval development occurs in sandy substrate. emerge in late summer. Specific details on timing and stage not documented.

Behavior

Alert and quick to like related , but lands quickly after short . This contrasts with C. formosa, which flies further and characteristically lands with bouncing and tumbling across the sand.

Ecological Role

Predatory , likely functioning as an active of small in sandy .

Similar Taxa

  • Cicindela lengi lengiNominate lacking the coppery thoracic underside; occurs south of C. l. versuta range
  • Cicindela lengi jordaiSouthwestern with broadly coalesced elytral maculations versus separated markings in C. l. versuta

More Details

Taxonomic placement

Despite morphological similarity to C. formosa, C. lengi belongs to subgenus Cicindela (Tribonia) rather than the nominate subgenus. The two represent in sandy , with differences in male confirming their distant relationship.

Conservation status

The C. lengi is not common throughout most of its range, though it may be locally abundant in some Nebraska .
