The Evolutionary History and Conservation of Speyeria Idalia (Lepidoptera: Nymphalidae)
Microsatellite data were concordant with previous analyses in that they indicated the Pennsylvania population was highly differentiated. Moreover, the greater resolution provided by microsatellites indicated the effects of recent habitat fragmentation for Midwestern populations when compared to …

Phylogenetic Relationships and Character Evolution of the Neotropical Butterfly Genus Hamadryas (Nymphalidae: Biblidinae)
<p>The butterflies in the genus <em>Hamadryas</em> are popular and noticeable representatives of the Neotropical Lepidoptera fauna. After a thorough taxonomic revision, 20 species were acknowledged within the genus, however no hypothesis of their phylogenetic relationship was proposed. The present …

Genómica de la diversificación de Heliconius cydno (Lepidóptera: Nymphalidae) en el norte de Suramérica: patrones geográficos y fenotípicos
Grandes eventos geológicos, como el levantamiento de los Andes y la formación de los valles interandinos, han sido determinantes en la configuración de la biodiversidad neotropical. Este estudio evalúa su influencia en la radiación adaptativa reciente (∼1.5 Ma) de Heliconius cydno, una mariposa …

Do Butterflies Use "Hearing Aids"?Investigating the Structure and Function of Inflated Wing Veins in Nymphalidae
… species within the subfamily Satyrinae (Nymphalidae) have been informally reported to possess a conspicuous "inflated" or "swollen" subcostal vein on each forewing. However, the function and taxonomic diversity of these structures is unknown. This thesis comprises both experimental and …

Comparative Morphology of Sensilla Styloconica on the Proboscis of North American Nymphalidae and Other Selected Taxa: Systematic and Ecological Considerations.
… Focus was on 76 species of North American Nymphalidae representing 45 genera and 11 subfamilies. Nomenclature for generalized and specific types of nymphalid sensilla is proposed. Written descriptions and micrographs are presented for each species studied. Morphological features were …

The effects of forest disturbance and fragmentation on fruit-feeding butterflies in Trinidad
… <br></br><br></br><i>Cissia arnaea</i> (Nymphalidae: Satyrinae) was present in significantly greatest abundance in 30 year selectively logged forest, even though canopy openness was not significantly different from that found in 5 year forest. Conversely, <i>Colobura dirce</i> …

Responses of fruit-feeding butterflies to selective logging in Sabah, Borneo
… Nymphalinae, Morphinae and Charaxinae (Nymphalidae). Traps were set up along four transects on existing paths and trails in unlogged forest (two transects, total length 4 km) and logged forest (two transects; total length 4 km). Traps were hung 1-2 m from the ground at 100 m intervals …

Spatial and temporal distribution of butterfly in highland and lowland forests of Johor
… from five families were collected and recorded. Nymphalidae was the most well- represented family. The values of Shannon Diversity Index (H’) and Species Evenness Index (E’) were higher in TNJER (H’=4.123; E’=0.471) than TNJGL (H’=3.405; E’=0.235). Based on elevations, 400 m a.s.l. had the …

Impacts of selective logging on tropical butterflies in Sabah, Malaysia
… in the sub-families satyrinae and morphinae (Nymphalidae) and the family Riodinidae. A total of 1825 adult butterflies was recorded from 34 species at 80 observation stations on 8km transects repeated four times per month for a period of one year (March 1999—February 2000). Most of the …

The role of life-histories in colonising a novel environment
… Butterflies of sub-tribe Mycalesina (Family: Nymphalidae) have undergone spectacular geographic radiations in Africa, Asia and Madagascar comprising some 320 species. Reconstructing ancestral states for habitat preference revealed a striking pattern that Mycalesina species have independently …

The Geographic Mosaic of Wolbachia Infection in Melanitis leda Butterfly Populations
… leda</em> butterflies (Lepidoptera: Nymphalidae: Satyrinae) for <em>Wolbachia </em>infection collected throughout its range in the Old World tropics and subtropics from Ghana to Fiji. Potential effects of the parasite on the evolution of its host were assessed by inferring phylogenies …

Coevolution of Heliconius spp. and Passiflora spp. : a phylogenetic comparison
Although a substantial amount of research has been done on all aspects ofHeliconius biology and their ecological interactions with Passiflora, there has not hitherto been a phylogenetic examination of this association for coevolution. To test the HeliconiuslPassilfora association for coevolutionary …

The butterfly community of a managed West African rainforest: patterns of habitat specificity, diversity, stratification and movement.
… Insgesamt wurden auf 75 ha 123 Arten der Nymphalidae in 8,400 Individuen gefangen während 996 Fangtagen innerhalb einer Trockenzeit und zweier Regenperioden. Es gab markante Schwankungen der Nymphaliden-Häufigkeit und Diversität zwischen den verschiedenen Jahren und Jahreszeiten, mit einer …

Cool as a caterpillar: Understanding the responses of butterflies to temperature across the life cycle
… butterfly responses to temperature. I found that Nymphalidae were the most studied family, likely owing to their high number of species, including large, charismatic and common species of cultural importance. In contrast, Riodinidae were rarely studied, likely due to their elusive nature and being …

Social life-styles in caterpillars: Behavioral mechanisms and ecological consequences
… nomadic butterfly species, Araschnia levana (Nymphalidae) was also studied. Caterpillars of E. lanestris are behavioral thermoregulators. In the laboratory (i.e. in the absence of solar radiation) tightly aggregated caterpillars are able to rise their body temperatures compared to ambient …

THE DEVELOPMENTAL BASIS AND EVOLUTION OF WING COLOR PATTERN IN BUTTERFLIES
Evolutionary biologists look to understand the processes underlying biodiversity. One aim of the field is to link the phenotype to its instructive genetic code, and to take advantage of homologies between species to ask what genetic changes generate the diversity of forms and shapes we see in …
