Identification

Distinguished from by combination of small size (13–15 mm), metallic green , and preference for coniferous forest areas with gravel and sand substrates. Specific diagnostic characters separating it from similar green Cicindela such as C. sexguttata require closer examination of elytral punctation and maculation patterns.

Taxonomic Note

The Wikipedia entry for this contains an error in the (lists Cicindela togata instead of C. denikei in the taxobox), though the text correctly identifies the species as C. denikei. The "Laurentian " references the Laurentian region of the Canadian Shield where the species occurs.

Conservation Status

No formal status assessment found in available sources. The ' restricted range in the upper Midwest may warrant given specificity for sandy forest substrates.
