NatureServe Status

Global Status: G2G4
Global Status Last Reviewed: 30Sep2014
Global Status Last Changed: 30Sep2014
Rounded Global Status: G3 - Vulnerable
Reasons: There are records for about 20 occurrences of this species, but approximately half of these records are from prior to 1974, even though this species is known to be attracted to lights. It is possible that this species is in decline, but also possible that recent records are just not available. The females are flightless and so the species probably has poor dispersal and recolonization abilities. It is possible that this species is declining, but more likely that it is not commonly collected because of the males flying during rainstorms. More information is needed before assigning this species a more definitive rank.
Nation: United States
National Status: N2N3

NatureServe Global Conservation Status Factors

Range Extent: 20,000-200,000 square km (about 8000-80,000 square miles)
Range Extent Comments: Approximately 50,000 square kilometers in the northern 2/3 of the peninsula and one record in the eastern Panhandle of Florida, USA.

Area of Occupancy: Unknown 4-km2 grid cells
Area of Occupancy Comments:  

Number of Occurrences: 6 - 80
Number of Occurrences Comments: There are records for about 20 occurrences, but only about ten of these have been documented since 1974.

Population Size: Unknown

Number of Occurrences with Good Viability/Integrity: Unknown

Short-term Trend: Unknown

Long-term Trend: Unknown
Long-term Trend Comments: It's possible that this species is declining since most records are so old, but there is no proof of a decline.

Intrinsic Vulnerability: Highly to moderately vulnerable.
Intrinsic Vulnerability Comments: Females are flightless.

Environmental Specificity: Unknown
Environmental Specificity Comments: Habitat requirements are unknown, but may be sandy uplands (Deyrup and Franz 1994).

Other NatureServe Conservation Status Information

Inventory Needs: Surveys in and around its current known range are needed, as most records for this species are over 20 years old.
