Cicindela limbata hyperborea
Hyperboreal Tiger Beetle
Cicindela limbata hyperborea is a northern subspecies of the sandy tiger beetle, distinguished by reduced white elytral maculations and smaller body size compared to other subspecies. These traits are interpreted as heat conservation adaptations for its far boreal climate. It occurs in open sand habitats within pine and poplar forests of northern Alberta, Saskatchewan, and adjacent Northwest Territories, separated from other subspecies populations by significant distributional gaps. The fragmented distribution of C. limbata and its subspecies likely reflects historical climate changes that caused expansion and contraction of open sand habitats.
