Borboletas (Lepidoptera: Hesperioidea e Papilionoidea) de Val de Serra, região central do Rio Grande do Sul, Brasil

Abstract

Abstract:The butterfly fauna of the Atlantic Forest Biome is reasonably well-known up to the southern limit of its distribution. However, there are knowledge gaps nearby the central region of Rio Grande do Sul State, whose forest areas are considered priorities for biological conservation. This study investigated the butterfly assemblage of a riparian fragment in an ecotone area between Mixed Ombrophilous Forest and Seasonal Decidous Forest, in Itaara municipality. From September 2005 to September 2006, after 105 net-hours through active search sampling, 877 butterflies were registered representing 104 species. Three more species were registered posteriorly, increasing total richness to 107. The most abundant species were the Nymphalidae Hermeuptychia hermes (Fabricius, 1775), Yphthimoides celmis (Godart, [1824]), Agraulis vanillae maculosa (Stichel, [1908]), Tegosa claudina (Eschscholtz, 1821) and Vanessa braziliensis (Moore, 1883). One new record for the State and four new ones for the central region were registered besides the southern endemic Papilionidae Euryades corethrus (Boisduval, 1836) and the Lycaenidae Arcas ducalis (Westwood, 1852), considered indicator of Atlantic forest preserved areas. Due to the representativeness of the registered fauna, it is suggested the increase of conservation efforts in the area and stimulation of new ecological studies with the local biodiversity.

Butterflies of Amazon and Cerrado remnants of Maranhão, Northeast Brazil

“…The richest family in our list was Nymphalidae, following the same pattern of other butterfly lists performed in Brazil (Zacca et al 2011, Morais et al 2012. Most recorded species of this family are widespread throughout the country, such as Hamadryas februa (Hübner, [1823]), Hamadryas feronia (Linnaeus, 1758), Hamadryas amphinome (Linnaeus, 1767), Junonia evarete (Cramer, 1779) and Agraulis vanillae (Linnaeus, 1758).…”

“…Most captured species of Pieridae and Papilionidae are considered widely distributed throughout the country and characteristic of modified habitats (Emery et al 2006, Zacca et al 2011, Morais et al 2012, suggesting that the study areas have been harmed by anthropic influences.…”

Distribution patterns of riodinid butterflies (Lepidoptera: Riodinidae) from southern Brazil

“…In particular, few other parts of the country were ever surveyed since as early as the end of the 19th and beginning of the 20th centuries. Most recently published inventories are related to Atlantic Forest habitats (Teston and Corseuil 1999, 2002Corseuil et al 2004;Iserhard and Romanowski 2004;Giovenardi et al 2008;Grazia et al 2008;Bonfantti et al 2009;Romanowski et al 2009;Iserhard et al 2010;Pedrotti et al 2011;Ritter et al 2011;Santos et al 2011;Bellaver et al 2012;Morais et al 2012), and the major gaps of information concern the Pampa (native grasslands), a biome restricted in Brazil to its extreme south and which covers about 2% of its surface, extending through Uruguay and northwest Argentina (Bencke 2009;Pillar et al 2009), exclusive to austral South America.…”

Insecta, Lepidoptera, Lycaenidae, Arcas ducalis (Westwood, 1852): first record from Uruguay

“…Arcas ducalis can be distinguished by the well-defined carmine disc and metallic yellow margin on the ventral hindwing (Bálint 2002(Bálint , 2006. Considered rare or vulnerable (Casagrande and Mielke 1993;Brown and Freitas 2000;Otero et al 2000;Morais 2012;), these species are the most exquisite of all Neotropical Theclinae, typical of large areas of natural wet forest and usually disappearing in disturbed areas. They are easy to find where present and are thus good indicators of undisturbed forest systems (Nicolay 1971;Brown et al 1998;Brown and Freitas 1999;Robbins et al 2012).…”

“…They are easy to find where present and are thus good indicators of undisturbed forest systems (Nicolay 1971;Brown et al 1998;Brown and Freitas 1999;Robbins et al 2012). Brown (1982) and D'Abrera (1995) pointed out that A. ducalis is endemic to the Atlantic Forest and until now it has been recorded in the Brazilian states of Espírito Santo (Brown and Freitas 2000), Rio de Janeiro, Paraná (Nicolay 1971;Dolibaina et al 2010Dolibaina et al , 2011, Santa Catarína (Nicolay 1971) and Rio Grande do Sul (Iserhard and Romanowski 2004;Iserhand 2009;Morais et al 2007Morais et al , 2012Giovenardi et al 2013). …”
