Cicindela duodecimguttata

Twelve-Spotted Tiger Beetle


Cicindela duodecimguttata, Twelve-Spotted Tiger Beetle

Family: Carabidae

Subfamily: Cicindelinae

Length: 12 - 15 mm

As both the common and scientific names say, this species has twelve spots, as seen in the photo. Two spots that aren't obvious in the photo are on the "shoulder," one on each elytron.

Cicindela duodecimguttata overwinters both as adults and as larvae. Development takes two years. The larval burrows are about 8 cm deep and are sometimes found in groups along the water's edge near where adults are hunting.

Adults of Cicindela duodecimguttata are often found in groups along stream margins, where they may be joined by groups of another common species, Cicindela repanda.

Like a number of other species of Tiger Beetle, the Twelve-spotted is most often seen in the adult form early and late in the season. Over most of its range, the adults are seldom seen in July.
