Fascinating facts about the Horace's Duskywing
- Horace's duskywing occupies a broad swath of the United States, extending from the Atlantic coast of Massachusetts through the Gulf Coast and across the interior to southeastern Utah, Colorado, north-eastern Arizona and New Mexico. Within this belt it inhabits a variety of open habitats, from woodland edges and clearings to fence rows, wooded swamps and power-line right-of-ways.
- Male Horace's duskywing butterflies have a costal fold on the forewing that holds yellow scent scales, while females bear a patch of scent scales on the seventh abdominal segment. Both sexes have a wingspan that varies between 36 and 49 mm.
- In the deep south and Texas, Horace's duskywing can complete three full generations each year, with adults emerging as early as January and persisting through November, taking advantage of the long warm season. Further north the cooler climate limits the butterfly to two generations, with flight activity confined to the period from April to September.
- Adult Horace's duskywings sip nectar from blossoms up to about 4.5 feet (1.4 m) above the ground. They visit a range of flowering plants, including dogbane, buttonbush, sneezeweed, goldenrod, peppermint, boneset and winter cress.
