First record of Hemiargus ammon from Jamaica
ABSTRACT A dedication, foreword (by Paul A. Opler), and preface are followed by an overview of previous research on the State's butterflies and skippers, a section on education and conservation, and an overview of the ecological and historical factors which influence the distribution of species in Ohio. A methods section details the sources and han...

A dedication, foreword (by Paul A.

A methods section details the sources and ha...
Four butterflies are endangered in Ohio. Three of these, Erynnis persius (Scudder), Incisalia irus (Godart), and Lycaeides melissa samuelis Nabokov, are restricted to the Oak Openings and use Lupinus perennis L. as the larval host. These species require early successional habitats and have probably declined since fire was eliminated as a factor in...
The status of eight species that are potential candidates for addition to the U.S. list of endangered species was assessed in 1985. Two of these, Phyciodes batesii (Nymphalidae) and Acronicta albarufa (Noctuidae), are known only from literature records, and their occurrence in Ohio is unverified. Three species, Neonympha mitchel/ii (Satyridae), Cat...
Satyrium edwardsii has generally been considered to be widespread and common in northwestern Ohio with scattered records through the remaining western portion of the state. However, after reevaluating historical records for this species, it was discovered that most of the supposed records were misdeterminations. Valid records exist for only five Oh...

... Most studies on this species have been conducted on populations throughout New England, Pennsylvania, and Ohio, but the range of P. virginiensis extends throughout the Appalachians southward into Virginia and North Carolina (Mather 1964). The native ephemeral forb Cardamine diphylla is the most common larval host plant of P. virginiensis, but there are also occasional small populations that use Cardamine concatenata, Cardamine dissecta, or Boechera laevigata when C. diphylla is absent (Calhoun and Iftner 1988;Shuey and Peacock 1989). C. diphylla emerges in early April, completes leaf expansion by May, and senesces by early June when the tree canopy begins to shade out the lower understory. ...

... Species were identified by overwinter strategy, as either migrant or resident. Residents were further identified by overwinter life stage and information about other traits were compiled from published sources [61][62][63][64][65][66][67][68][69] and used as covariates in our analyses (see Supplement 1 (S1) for focal trait descriptions, data by species, and sources). We include observations over the years 2012-2018, spatially aggregating data using 1-degree grid cells, which correspond to 111 km latitude, and 83-90 km longitude (Fig. 1). ...

... Only remnants of wetland and prairie habitat remain in the state due to human modification of the landscape. Some rare butterflies have declined due to forest succession following suppression of disturbances [26]. Agriculture and pastures (50%), forest (30%), and urban development (10%) are the predominant land-use/land cover classes [27]. ...
... We studied butterfly population trends across the state of Ohio in the Midwestern USA. Over its 116,100 km 2 land area, Ohio has a mosaic of habitat types due to its partially glaciated history and its place at the confluence of Midwestern prairies, the Appalachian Mountains, and the boreal forest [25]. Only remnants of wetland and prairie habitat remain in the state due to human modification of the landscape. ...
... In 1984 Eric Metzler discovered P. hebardi in southern Ohio. Additional populations were discovered within 5 km of the 1984 site in 1985 and 1986 (Shuey et al., 1987). ...
