Status and Natural Heritage Inventory documented occurrences in Wisconsin

The table below provides information about the protected status - both state and federal - and the rank (S and G Ranks) for A Leafhopper (Attenuipyga vanduzeei). 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.

Species guidance

Identification: Tan, elongated, and flattened leafhopper with the crown of the head extended to form about 1/3 the total body length. Body length of female 14.8-17.5mm. Body length of male 11.0-12.6mm.

Similar Species: Could be confused with a stick insect but is much smaller than even nymphal Diapheromera spp. Dorycara platyrhyncha is similar but not as elongate.

Habitat: Sites in Wisconsin are on limestone bluff "goat prairies". One is on a bluff of sandstone. Little bluestem (Schizochyrium scoparium), sideoats grama (Bouteloua curtipendula), and prairie dropseed (Sporobolus heterolepsis) are dominant grasses on the sites. Found on tallgrass prairie in Kansas.

Host Plant: Probably Indiangrass (Sorghastrum nutans) or prairie dropseed (Sporobolis heterolepsis). None have been taken on Muhlenbergia cuspidata in Wisconsin though that grass has been reported elsewhere. Exuvia, nymphs taken on prairie dropseed.

State Distribution: Southwestern Wisconsin and Pepin County in the northwest.

Global Distribution: Found in the following states/provinces: KS, IL, WI, and MB.

Status Comments: Highly localized even within habitat supporting foodplants.

Rationale for Species Listing and Threats: Loss of prairie habitat and inappropriate burn management.

Phenology: Adults present late June to late August.

Life and Natural History: Probably overwinters as an egg. Females were observed in the laboratory moving between prairie dropseed and sideoats grama with attempts at ovipositing in a stem of the sideoats grama (Sauer and Maurer, 2001).

Survey Guidelines: Sweep netting of hostplants also yellow pan traps. Adults lie motionless in the net and are difficult to discern from plant materials. Look for small red eyes. The green nymphs tend to be more active in the net and males are more active than females.

Inventory, Monitoring and Research Needs: This species is easy to miss. Further surveys needed in prairie sites.

Natural community (habitat) associations

The table below lists the natural communities that are associated with A Leafhopper. Only natural communities for which A Leafhopper 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.

Ecological landscape associations

The table below lists the ecological landscape association scores for A Leafhopper. The scores correspond to the map (3=High, 2=Moderate, 1=Low, 0=None). For more information, please see the Wildlife Action Plan.

This map shows the probability of A Leafhopper occurring in each of Wisconsin's Ecological Landscapes.  Actual scores can be found in the table to the left.

Landscape-Community combinations of highest ecological priority*

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.

Issues/threats and conservation actions

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.
