“…The presence of particular Viola species did not appear to influence the activity of butterflies in our field sites. This result is consistent with laboratory rearing trials, which have not found any evidence of Viola preference in reproducing S. diana females, or developing larvae [11]. All of the violet species observed in this study are widely distributed in southeastern US forests [24].…”

“…While a number of violet species have been used to successfully rear S. diana in laboratory settings [8][9][10][11], to our knowledge there are no documented reports of Viola usage by S. diana from natural habitats. Evidence does suggest that S. diana may specialize in its nectar use, preferring high-quality nectar resources when available [12][13][14].…”

We present four summers (2006)(2007)(2008)(2009) of field observations of the Diana fritillary, Speyeria diana (Cramer, 1777), throughout the Southern Appalachian Mountains, USA, in the eastern portion of its distribution. We describe our observations of resource use by S. diana in sites located in Georgia, Tennessee, South Carolina, North Carolina, and Virginia. Butterflies imbibed nectar from five genera (>11 species) of flowering plants and also imbibed liquid from dirt roads and horse manure. The majority of butterflies (57%) were observed feeding on milkweed, Asclepias spp., a high-quality nectar-producing plant which is known to be an important resource for many Lepidoptera. We documented 14 species of Viola spp., the larval host plant used by Speyeria, in our survey sites. All butterflies were marked to observe their movement. Recapture rates ranged from 17% to 56%, suggesting that dispersal of S. diana out of suitable habitat was somewhat limited.

“…Each female Diana will lay thousands of eggs singly on ground litter in the vicinity of violets ( Viola spp., Violacea) in late summer before expiring (Allen, ; Ross & Henk, ; Wells et al ., ). First‐instar larvae hatch after several weeks and immediately burrow into the forest floor litter where they overwinter in diapause.…”

Global warming can affect the distributions, phenology and, ultimately, conservation status of species worldwide, but most published studies on its biological effects have focused on higher latitude species. We extended this work to the Diana fritillary, a butterfly which once ranged throughout the Southeastern United States but now is severely restricted in range. We searched for all scientific records of this species, from publications, catalogued and uncatalogued specimens in public and private collections in the United States and Europe, online databases, contemporary field surveys by scientists and amateurs, and our own field surveys. We analysed these records for shifts in latitude, longitude, elevation and phenology. We found that the Diana fritillary has disappeared entirely from the Atlantic coastal plain, where it was first described, and from interior lowland sites. It now persists in two disjunct parts of its former range, the Southern Appalachian Mountains and the Interior Highlands of Oklahoma and Arkansas, and is shifting to higher elevations at about 18 m per decade. In addition, females are being collected 4.3 days earlier per decade though males, which emerge first, have not shifted their phenology. All these patterns are weakly dependent on latitude. These shifts in distribution and phenology are consistent with the predicted effects of global warming, but we review other large scale changes to the region which also might contribute singly or jointly to these patterns. We also comment on the implications for the conservation of this species.

“…Nevertheless, some butterfly species appear to have greatly benefitted from population augmentation enabled by captive breeding programs [93]. Augmentation efforts are rare with Speyeria because they are difficult to successfully rear in captivity and the rearing process is labor intensive [94,95]. Captive reared S. zerene hippolyta have been used in a few conservation plans [96], but little other work has been done.…”

Speyeria (Nymphalidae) are a conspicuous component of the North American butterfly fauna. There are approximately 16 species and >100 associated subspecies (or geographical variants). Speyeria are univoltine, occupy a wide range of habitats, overwinter as first instar larvae, and feed only on native violets. Speyeria species have become a model group for studies of evolution, speciation, and conservation. Several species and subspecies are threatened or endangered. The reasons for this vary with the taxa involved, but always involve the degradation or loss of quality habitat for larvae and adults. The impacts of climate change must be considered among the causes for habitat degradation and in the establishment of conservation measures. In addition to increasing the available habitat, conservation efforts should consider maintaining habitat in a seral “disturbed” successional stage that selectively favors the growth of violets and preferred adult nectar sources. A major future challenge will be determining the most effective allocation of conservation resources to those species and subspecies that have the greatest potential to respond favorably to these efforts.
