TL;DR: 47 samples from the Martignoni baculovirus collection were characterized by PCR amplification of the lef-8 gene, which led to the identification of sequences from viruses that either were not present in the database, or had been identified, but not further characterized.

TL;DR: It is suggested that meaningful and localized ecological divergence may occur in the absence of easily recognizable genetic divergence, due to either ongoing gene flow or the recent diversification in the Hemileuca maia species group.
Abstract: The Hemileuca maia species complex occurs across the North American continent and consists of six named taxa, and several others that were recently synonymized Taxa exhibit a wide span of adult flight periods, dramatic shifts in host-plant use and occur in a range of habitats, all of which would suggest unrecognized diversity We used one mitochondrial and three nuclear genes to generate 3900 bp per individual, including samples from every ecotype in the species group across the United States from New England to central Florida to California We assessed phylogenetic relationships using both maximum likelihood and Bayesian phylogenetic methods Results suggest very low levels of divergence across most of the continent and low levels of genetic structure – even between some recognized species that maintain clear ecological difference in sympatry Our results suggest that meaningful and localized ecological divergence may occur in the absence of easily recognizable genetic divergence, due to either ongoing gene flow or the recent diversification in the group

TL;DR: A survey of known and potential H mileuca sites was taken in order to confirm previously known populations and to discover new populations in Wisconsin, a state previously not included in recent Great Lakes Hemileuca complex research projects.
Abstract: A popUlation of Hemileuca maia species complex was observed feeding on Menyanthes trifoliata and Betula pumila. This confirms the presence of a second population of these m ths using M. trifoliata in Wisconsin, and is only the fourth known locality for such populations. This is the first report of Hemileuca feeding on B. pumila in Wisconsin. The Hemileuca populations of the Great Lakes region are discussed, and the first map of the distribution Hemileuca in Wisconsin is provided. The Hemileuca maia (Drury) species complex in the Great Lakes region consists of two species, H. maia and H. nevadensis (Stretch). Both are consid ered good species, but are recognized by sparse or unreliable morphological and inconsistent ecological criteria (Ferguson 1971, Covell 1984, Scholtens & Wagner 1994, Legge et aL 1996, Tuskes et al. 1996). In the Great Lakes region, these species come together to produce a confusing array of morphological, eco logical, and behavioral traits. In addition, Great Lakes populations have not yet been differentiated using molecular techniques (Legge et al. 1996). Hemileuca in the Great Lakes region that demonstrate unique food plant associations are considered imp rtant for two reasons. First, these popula tions may contai an unnamed sibling species (Tuskes et al. 1996), or are otherwise phylogenetically distinct and therefore have conservation potential (Legge et al' 1996). Second, allopatric and parapatric juxtaposition of these populations with each other and with nominate H. nevadensis and H. maia, coupled with the recent glaciation of the region, pose several challenging op portunities for studies in biogeography, gene flow, and evolution. With these prospects in mind, a survey of known and potential H mileuca sites was un dertaken in order to confirm previously known populations and to discover new populations in Wisconsin, a state previously not included in recent Great Lakes Hemileuca complex research projects.

TL;DR: The presence of transitional phenotypes and the host plant and habitat suggest that Michigan popu lations are a single, variable species, which calls into question the taxonomic distinctness of the three eastern buckmoth species.
Abstract: The habitats and host plants of buckmoths (Hemileuca: Saturniidae: Hernileucinae) in Michigan are described and compared to those of the three species known from eastern North America, H. mala, H. nevadensls, and H. lucina. Michigan populations show variation in host plant and habitat use spanning the entire range of all three species. The presence of transitional phenotypes and the host plant and habitat d ta suggest that Michigan popu lations are a single, variable species. These things combined with the interme diate geographical location of Michigan's populations call into question the taxonomic distinctness of the three eastern buckmoth species.
