| Distribution | DISTRIBUTION: Statewide, including the immediate coast, where there are many records for the Outer Banks.
|
| Abundance | ABUNDANCE: Widespread and generally fairly common to common, though never as numerous at any time as the Juvenal's is in spring. However, it is seemingly uncommon before June. The abundance seems reasonably even over the state, though somewhat less numerous in the Mountains. Large numbers are seldom seen; "frequently encountered" better characterizes its status, rather than an abundance label. However, it can be common in some large gardens and arboretums.
|
| Flight | FLIGHT PERIOD: Probably three broods, but no gap in flight periods from early June through the fall season. Downstate, the first occurs from mid-March to mid-May, the second from late May or early June to early August, and the third from early August to early October. Brood dates in the Mountains are not yet clear, but it flies from early April to late September. The first brood is obscured by the difficulty in separating the species from the common/abundant Juvenal's Duskywing, but certainly the first brood of Horace's is rather small (based on photographic review).
|
| Habitat | HABITAT: Widespread, but usually near hardwood forests; wooded borders and openings, dirt roads, powerline clearings, etc. are utilized. Habitats are similar to that of the Juvenal's, except that Horace's generally avoids the interior of forests, and Horace's often ventures to gardens and other suburban places. Horace's occurs near the coast more than does Juvenal's and can be numerous on coastal islands.
|
|
| | Plants | FOOD AND NECTAR PLANTS: The foodplants are oaks (Quercus spp.). As with other duskywings, adults nectar on many flowers but are often seen on dirt roads and trails. It is the main duskywing species seen in gardens across the state; in fact, a duskywing in a yard or garden needs to be assumed as this species, until proven otherwise.
|
| Comments | COMMENTS: This species looks quite like the Juvenal's, and thus observers may need to "wait" until after the Juvenal's have finished flying in mid-May before they can be confident about identifying a Horace's. The male Horace's is somewhat darker and plainer brown than a male Juvenal's, with little if any silvery scaling. The female Horace's is slightly more checkered (especially with black blotches) on the fore wings than the female Juvenal's, but the lack of the two pale spots on the under hind wing of the Horace's is the best field mark. Male Horace's are also frequently difficult to separate from Zarucco Duskywing, a fact that many field guides overlook.
