State status

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 (Laevicephalus vannus). 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: A leafhopper. This genus is distinguished by the distinctly pointed head and male abdomen. Wings are as long as the body and any dark markings are confined to the ends of the veins. L. vannus is yellow with white tegmina and yellow veins. Head of the male is bluntly pointed, female head is longer.

Similar Species: The head of L. vannus lacks longitudinal stripes found in others of the genus. L. minimus has greenish tegmina with narrow yellow veins that barely contrast with the background color. It ranges into at least southwestern Wisconsin and is a specialist on Bouteloua curtipendula, side-oats grama grass.

Habitat: Dry prairie, barrens.

Host Plant: Members of this genus are highly host specific especially in the northern parts of the range and many feed on Bouteloua sp., the grama grasses. Hicks and Whitcomb have stated that L. vannus uses Bothriochloa spp. (1993). The only species of this genus to come close to Wisconsin is silver beardgrass or silvery bluestem, B. laguroides, reported from Illinois.

Associated Species: Perhaps Laevicephalus unicoloratus, a common species on bluegrass, may be present.

State Distribution: Sauk Co. possibly Monroe Co.

Global Distribution: Found in the following states: NM, TX, OK, SD, WI, and MN.

Phenology: Collected Aug 15 in Wisconsin.

Inventory, Monitoring and Research Needs: Continue to survey potential habitat. Identification of the foodplant is needed.

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.
