Arctiinae (Lepidoptera, Arctiidae) coletados em unidades de conservação estaduais do Rio Grande do Sul, Brasil. O presente estudo foi realizado com o objetivo de analisar a composição das comunidades de Arctiinae no Parque Estadual do Espigão Alto (Barracão), Parque Estadual de Rondinha (Sarandí), Parque Estadual do Turvo (Derrubadas) e na Reserva Biológica de Ibirapuitã (Alegrete). Dez armadilhas luminosas foram utilizadas para coletar os lepidópteros, de novembro de 2000 a fevereiro de 2001, amostrando-se uma noite em cada local. Os lepidópteros foram identificados aos níveis de subfamília, tribo e, quando possível gênero e espécie. Obteve-se um total de 5.969 arctiíneos pertencentes a 137 morfo espécies, distribuidos em seis tribos.
Arctiinae (Lepidoptera, Arctiidae) collected in protected unities in Rio Grande do Sul State, Brazil. The objective of this work was to analyze the composition of the Arctiinae communities at Parque Estadual do Espigão Alto (Barracão), Parque Estadual de Rondinha (Sarandí), Parque Estadual do Turvo (Derrubadas) and at Reserva Biológica de Ibirapuitã (Alegrete). Ten light traps were used to collect the lepidopterous from November/2000 to February/2001, sampling one nigth per area. The lepidopterous were identified at subfamily and tribe levels and, when it was possible, at genera and species levels. A total 5,969 Arctiinae belonging to 137 morpho species, distributed in 6 tribes were collected

Abstract:Here is presented a guide to identify the species of Scarabaeinae occurring in Santa Maria, Rio Grande do Sul, compiled from the literature and captured between May 2009 and April 2010 in forest fragments. A dichotomous key, characterization, illustrations (species collected) and ecological information for 35 species are provided.

ABSTRACT. Copro-necrophagous beetles (Coleoptera: Scarabaeidae: Scarabaeinae) from Atlantic Forest fragments of Silveira Martins, Rio Grande do Sul, Brazil. The fauna of Scarabaeinae (Coleoptera: Scarabaeidae) was sampled using pitfall traps baited with human excrement and rotten fish in forest fragments in Silveira Martins, Rio Grande do Sul, Brazil, from November 2010 to January 2011. A total of 1,611 individuals were sampled, belonging to six tribes, 11 genera and 28 species. The most abundant species were Canthon latipes Blanchard, 1845 (49.9%), C. chalybaeus Blanchard, 1845 (13.9%), Deltochilum sculpturatum Felsche, 1907 (4.9%), and Eurysternus caribaeus (Herbst, 1789) (4.3%), which accounted for 73% of the total individuals captured. Traps baited with human excrement captured a higher number of species than those baited with rotten fish. There was no statistically significant difference between the kinds of baits used in relation to the abundance of Scarabaeinae. Most of Scarabaeinae species was represented by generalist feeding habits and tunneler behavior. The community sampled follows the general patterns of trophic and behavioral structure of Scarabaeinae found throughout the Neotropical region.
