There is no overview information available for that species.

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 Pink-streak (Dargida rubripennis). 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.

Dargida rubripennis is not tracked by the Wisconsin Natural Heritage Inventory Program at this time (this species is not on the NHI Working List).

Species guidance

Identification: A medium size straw colored noctuid moth with prominent pink streaks on the forewing and often a contrastingly dark olive thorax. The combination of the pink and size is absolutely diagnostic for adults. Wingspan 3.2-3.7cm.

Habitat: Wisconsin sites are limestone bluff prairieand an eastern mesic site with oaks. In other states may be found in sand prairies (IL), short grass prairie and cedar glades (OH), wet and mesic prairie (Northern OH) and weedier situations.

Nectar Source: Adults may or may not feed. They do not come to sugar baits and have not been seen on flowers.

Host Plant: Larvae feed on grasses and have been reared in the lab on crabgrass by Godfrey (1972). Schweitzer has seen many ovipositions and larvae in NJ all on switchgrass, Panicum virgatum. Evidence suggests the species may be associated with Indiangrass, Sorghastrum nutans, in Ohio.

State Distribution: Kenosha, Waukesha, Grant, Trempealeau Cos.

Global Distribution: MA, ON to FL west to MN, TX.

Phenology: Adults present late July into early August.

Life and Natural History: It is not unlikely, but so far undocumented, that some pupae may remain in diapause an extra year or more and do not emerge until the second year or later. Most Noctuids are nocturnal and females attract males by the release of pheromones. Females oviposit soon after dark. Eggs are laid in groups inside flowering stems. Larvae apparently feed internally for the first instar. The last instar feeds mainly on the developing seeds. It is believed intermediate instar larvae eat foliage as well as flowers and seeds. The last two instar larvae at least, are also nocturnal and leave the feeding areas by day. Larvae are mature in September and probably none remain by 1 October. There is only one brood and the rest of the year is spent as pupae several centimeters underground.

Survey Guidelines: Blacklight in July and August for adults.

Inventory, Monitoring and Research Needs: Learn foodplant in various parts of the range.
