Pangrapta decoralis

The decorated owlet can be distinguished from similar small erebid moths by its specific wing pattern: forewings show a combination of wavy transverse lines and a small discal spot, with a relatively uniform brown ground color lacking strong contrasting patches. The pale hindwings separate it from underwing moths (Catocala), which have boldly patterned hindwings. Genitalia examination may be required for definitive separation from congeneric species.

Small moth with wingspan of 20–28 mm. Forewings are brown with darker markings and a pattern of lines and spots that provide camouflage against bark and leaf litter. Hindwings are paler, often with a subtle banding pattern. The overall coloration is cryptic, typical of many underwing and owlet moths in the family Erebidae.

Found in wooded and shrubby habitats where Vaccinium host plants occur, including forests, bogs, and heathlands. Adults are frequently attracted to light.

North America: from Alberta, Saskatchewan, and Manitoba in Canada eastward to Nova Scotia, and southward through the eastern United States to Florida and Texas.

Adults are on wing from May to September. Two to three generations per year occur throughout most of the range, with peak activity varying by latitude.

Larvae feed on Vaccinium species, including blueberries and cranberries. Adult feeding habits are not documented.

• Vaccinium - larval food plantIncludes blueberry and cranberry species

Multivoltine with two to three generations per year. Overwintering stage not explicitly documented in available sources.

Adults are nocturnal and attracted to light. Larval behavior is not well documented.

Larvae function as herbivores on Vaccinium shrubs in forest and bog ecosystems. Adults may serve as prey for nocturnal predators including bats and birds.

Larvae feed on economically important Vaccinium crops, including blueberries and cranberries, though the species is not considered a major agricultural pest. The moth is frequently encountered by citizen scientists and contributes to biodiversity records.
