Species guidance


Identification: Dark brown tiger beetle with a very hairy neck and markings on the elytra reduced or nearly lacking. The humeral lunule on the elytron is shaped like a "G". Hairy pronotum almost looks white. Ventral side is covered with long white hairs. The shiny green legs and the thorax are also hairy. Long legs allow it to stand high in the shifting sand habitat. Length: 13-14 mm.

Similar Species: C. punctulata has green pits along the suture of elytra and is found away from water. C. longilabris has a long labrum and is also found away from water. C. repanda is very similar in appearance and is found on mudflats and sandbars but the anterior maculation is shaped like a "C".

Habitat: Sand beaches along Lakes Superior, Michigan and along large rivers. Larvae burrow into the beach behind the littoral drift area where the substrate is moist but less likely to swamp, but in front of the vegetated stabilized upper beach. The burrows go straight down 5-8 inches. Larvae are very picky about the moisture content of the sand and will abandon burrows that have become too wet or dry.

Associated Species: May be found with C. repanda.

State Distribution: Ashland, Bayfield, Door, Milwaukee Cos. Historically most counties along Lake Michigan.

Global Distribution: This northern subspecies occurs in the Great Lakes Region east to Labrador and Newfoundland.

Status Comments: This species has disappeared from many sites where it was once abundant in the eastern Great Lakes though still present at a few sites on Lakes Ontario and Huron. Subspecies rhodensis is known to be extant at a handful of sites in Ontario, Wisconsin, and Minnesota.

Rationale for Species Listing and Threats: Loss of habitat to beachside homes, recreational activities in lakeside parks primarily excessive trampling and ATV traffic.

Phenology: Mid May through September but most abundant in June and August.

Life and Natural History: Eggs are laid in moist sand in late June or early July. Third instar larvae overwinter and open the burrow in May to feed. Pupation occurs in June or July. The new emerged adults may have to overwinter again before reemerging sexually mature the next spring. A two year overlapping life cycle results in newly emerged adults with year-old adults in midsummer.

Survey Guidelines: Catch adults with an aerial net on the beach.

Inventory, Monitoring and Research Needs: Survey historic sites and island beaches.
