The table below provides information about the protected status - both state and federal - and the rank (S and G Ranks) for Hairy-necked Tiger Beetle (Cicindela hirticollis rhodensis). See the Working List Key for more information about abbreviations. Counties shaded blue have documented occurrences for this species in the Wisconsin Natural Heritage Inventory database. The map is provided as a general reference of where occurrences of this species meet NHI data standards and is not meant as a comprehensive map of all observations.
Note: Species recently added to the NHI Working List may temporarily have blank occurrence maps.

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.

The table below lists the natural communities that are associated with Hairy-necked Tiger Beetle. Only natural communities for which Hairy-necked Tiger Beetle is "high" (score=3) or "moderate" (score=2) associated are shown. See the key to association scores for complete definitions. Please see the Wildlife Action Plan to learn how this information was developed.
| Natural community | Score |
|---|---|
| Great Lakes Beach | 3 |
| Lake Michigan | 2 |
| Lake Superior | 2 |
The table below lists the ecological landscape association scores for Hairy-necked Tiger Beetle. The scores correspond to the map (3=High, 2=Moderate, 1=Low, 0=None). For more information, please see the Wildlife Action Plan.
| Ecological landscape | score |
|---|---|
| Central Lake Michigan Coastal | 3 |
| Northern Lake Michigan Coastal | 3 |
| Southern Lake Michigan Coastal | 3 |
| Superior Coastal Plain | 3 |
Ecological priorities are the combinations of natural communities and ecological landscapes that provide Wisconsin's best opportunities to conserve important habitats for a given Species of Greatest Conservation Need. The 10 highest scoring combinations are considered ecological priorities and are listed below. More than 10 combinations are listed if multiple combinations tied for 10th place. For more information, please see the Wildlife Action Plan.
* Ecological priority score is a relative measure that is not meant for comparison between species. This score does not consider socio-economical factors that may dictate protection and/or management priorities differently than those determined solely by ecological analysis. Further, a low ecological priority score does not imply that management or preservation should not occur on a site if there are important reasons for doing so locally.
Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the WWAP because lack of information can threaten our ability to successfully preserve and care for natural resources.
