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 Seed Bug (Slaterobius quadristriata). 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: The members of the family Lygaeidae are true bugs in which the front portion of the wing is hardened (corium) and the posterior is membraneous. Milkweed bugs are in this family. They have 4-segmented antennae, 3-segmented tarsi, and two ocelli on the head. The antennae attach below the eyes. The front wings have 4-5 veins. The body shape is oval and flattened. Black with the head punctate and minutely wrinkled but not setose. Dull black pronotum has a distinct, narrow collar. Dull black corium with four white/gray stripes converging toward the base. The membraneous portion of the wing is brown with a pale spot. Legs are brown, paler at the knees, tarsi, and femora. Length of male about 7.5mm.

Similar Species: The common Slaterobius is insignis. It is a ground dweller and resembles an ant. It is found in dry fields throughout the summer. Head of this species is covered with setae.

Habitat: Lygaeides are seed-feeders and live on the ground or on vegetation.

Global Distribution: Eastern U.S.

Phenology: Collected in New Jersey on July 4 and September 7.

Natural community (habitat) associations

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