Summary

Did you know?

The hairy-necked tiger beetle has declined in many parts of its range, mainly due to habitat alteration and recreational pressure on its sandy habitats.

State Ranking Justification

This species has a limited state distribution, narrow habitat requirements, and is declining in much of its range, including New York, due to beach front development and overuse of beaches. The rank was calculated using NatureServe's Element Rank Calculator, version 2.0.

Short-term Trends

No information on short-term trends is available.

Long-term Trends

Approximately 7 of 40 historical occurrences on Long Island appear still to be occupied, with most having been surveyed recently. No historical information is available for New York's Great Lakes populations.

Conservation and Management

Threats

The overall threat impact is considered Very High. Beach front development and overuse of beaches are major threats. In particular, vehicle traffic that crushes larval burrows is a chief cause of decline.

Conservation Strategies and Management Practices

The most critical management need for the hairy-necked tiger beetle is the control and/or elimination of vehicle and other recreational traffic on occupied beaches, which can crush larval burrows. Beach grooming and stablization measures also adversely affect larval and adult beetles.

Research Needs

A primary research need is further description of the morphology, habitat use, and distribution of C. h. hirticollis and C. h. rugifrons, which apparently overlap at several locations in New York (Schlesinger and Novak 2011). Research is needed on the reasons C. hiritcollis is able to persist on some beaches where C. dorsalis dorsalis is not. Research is also needed on microhabitat separation (niche partitioning) among C. hirticollis, C. repanda, and C. tranquebarica.

Habitat

Habitat

This beetle occurs on sandy beaches associated with large lakes (Ontario and Champlain) and the ocean. Beaches can be narrow or wide, with varying amounts of dune vegetation, but usually with some associated dunes intact.

Associated Ecological Communities

  • Great Lakes dunes (guide)
    A community dominated by grasses and shrubs that occurs on active and stabilized sand dunes along the shores of the Great Lakes. Unstable dunes are sparsely vegetated, whereas the vegetation of stable dunes is more dense, and can eventually become forested.
  • Maritime beach (guide)
    A community with extremely sparse vegetation that occurs on unstable sand, gravel, or cobble ocean shores above mean high tide, where the shore is modified by storm waves and wind erosion.
  • Maritime dunes (guide)
    A community dominated by grasses and low shrubs that occurs on active and stabilized dunes along the Atlantic coast. The composition and structure of the vegetation is variable depending on stability of the dunes, amounts of sand deposition and erosion, and distance from the ocean.

Associated Species

  • Bronzed Tiger Beetle (Cicindela repanda)
  • Oblique-lined Tiger Beetle (Cicindela tranquebarica)

Range

New York State Distribution

This species is primarily recorded from Long Island with some recent records from the shores of Lake Champlain and Lake Ontario. It is primarily a beach species.

Global Distribution

The hairy-necked tiger beetle is widely distributed throughout North America. The subspecies C. h. hirticollis ranges from the southeast US to northern New York, and west to the southern Midwest. The subspecies C. h. rugifrons occurs in New York, New England, and the upper Midwest (Pearson et al. 2006).

Identification Comments

Identifying Characteristics

Like other tiger beetles in the northeast, the hairy-necked tiger beetle is a small insect approximately 0.5 inches (12-14 mm) in length with long sickle-shaped mouthparts, long thin antennae with 11 segments, a long body form with head and eyes wider than the middle portion (thorax) of the body, long thin legs for running, and a pattern of white markings (maculations) on wing covers (elytra) located on top of the main portion of the body (abdomen). The elytra of the hairy-necked tiger beetle are brown or bronze; the anterior maculations are G- and reverse-G-shaped. As with other tiger beetles, the larvae live in burrows in the ground and are white and grublike in appearance. (Pearson et al. 2006, Leonard and Bell 1999)

Characters Most Useful for Identification

The hairy-necked tiger beetle, true to its name, has a hairier "neck" (thorax) than other tiger beetles in similar habitats; however, this character can be challenging without other species in hand for comparison. The G shape at the front of the elytra, as opposed to a C shape in C. repanda, is the best character for distinguishing this beetle.

Best Life Stage for Proper Identification

All tiger beetles are best identified as adults. Far fewer good diagnostic characters are available for identifying larvae, many species lack formal or complete larval descriptions, and there is no comprehensive key for those larvae that have been described (Pearson et al. 2006).

Behavior

Most adult tiger beetles are diurnal animals, spending the warmer parts of the day running along the surface of the ground hunting, eating, and mating. They pursue prey by running in short, fast spurts interspersed with brief stops. Tiger beetles are most active on warm, sunny days and will retreat to burrows or hiding places at sunset or when skies become overcast.

Diet

Tiger beetles are predatory on other insects. Little is known about specific diet items of the hairy-necked tiger beetle.

Similar Species

  • Bronzed Tiger Beetle (Cicindela repanda)
    C. repanda has a C shape at the front of the elytra and less dense hairs on the thorax.
