Schinia sanguinea

Geyer, 1832

Bleeding Flower Moth

Schinia sanguinea, commonly known as the bleeding , is a small to North America. are active in autumn, primarily September through October, and are characterized by their distinctive pinkish-red with darker markings. The is notable for its specialized larval association with Liatris (blazing star) species, where feed on developing flowers and seed . The occupies a broad geographic range across eastern and central North America, with a disjunct in Ontario.

Identification

Distinguished from by the combination of pinkish-red coloration with dark markings and autumn period. Schinia carmosina, formerly considered a synonym, has been elevated to status and differs in genitalic structure and subtle coloration differences. Other similar Schinia species typically show different color patterns (, , or ) or occur in different seasons. Examination of may be necessary for definitive identification where ranges overlap with similar species.

Habitat

Prairie and grassland , particularly where plants (Liatris ) occur. Associated with open, sunny environments including prairies, meadows, and occasionally disturbed grasslands. Elevational range not well documented but occurs across plains and lower montane regions.

Distribution

Eastern and central North America: from North Carolina south to Florida, west to Texas, and north to Montana. Disjunct present in Ontario, Canada. Absent from far western North America and most of the Northeastern seaboard north of North Carolina.

Seasonality

active from September to October. Single brooded (). Larval stage occurs during summer months, coinciding with flowering and seed development of plants.

Diet

feed on flowers and developing seed of Liatris (blazing stars, gayfeathers). feeding habits not documented; presumed to take nectar from flowers including those of plants.

Host Associations

Life Cycle

with four stages: , , , . Eggs laid on or near flowers. Larvae feed on developing flowers and seeds, passing through multiple . occurs in soil or leaf litter. stage presumed to be pupa, with adults emerging in autumn.

Behavior

are but may be active at dusk. Attracted to light. Resting posture with folded tent-like over body. Larval involves feeding within flower , often concealed among florets.

Ecological Role

As a , contribute to seed on Liatris, potentially influencing reproductive success. may serve as when visiting flowers for nectar. Serves as for including birds, bats, and insectivorous .

Human Relevance

No direct economic importance. Occasionally encountered by prairie ecologists and . Potential for prairie quality due to specialized association. Not known to be of concern rangewide, though local may be vulnerable to prairie habitat loss.

Taxonomic history

Schinia carmosina was recently elevated from synonymy, clarifying that reports of S. sanguinea from some areas may refer to this distinct .

Host plant specificity

The association with Liatris appears obligate; no alternative records are known.
