1. Temporal distribution of fruit-feeding butterflies (Lepidoptera, Nymphalidae) in the eastern extreme of the Amazon region
RESUMO A pluviosidade é considerada um dos fatores mais determinantes na sazonalidade de insetos na região amazônica. No entanto, poucos estudos analisaram a dinâmica temporal de borboletas frugívoras na Amazônia brasileira, especialmente em sua porção oriental. Aqui, avaliamos os padrões de diversidade e a distribuição temporal de borboletas frug

2. Use of microhabitats affects butterfly assemblages in a rural landscape
Abstract Landscapes composed of small rural properties may support highly heterogeneous habitat, because they often cover distinct types of land uses adjacent to surrounding forest fragments. Many butterfly species may benefit from this kind of landscape, as very distinct microhabitats can be found in a very restricted spatial scale. To better understand how

3. Numerical study of upstream disturbances on the performance of electromagnetic and ultrasonic flowmeters
ABSTRACT Electromagnetic and ultrasonic flowmeters are high precision devices that can measure the water flow in pressurized irrigation networks. In these networks, the inadequate installation distance of flow control valves generates upstream disturbances which will increase measurement errors and reduce the accuracy of the equipment. Therefore, estimating

4. Immature stages of the Selaginella -feeding Euptychia mollina (Nymphalidae: Satyrinae) from the Brazilian Amazon
ABSTRACT The present paper describes the immature stages of the Neotropical satyrine butterfly Euptychia mollina (Hübner, [1813]) from the Brazilian Amazon Forest. Eggs were laid singly on the under surface of the fronds of its host plant, Selaginella sp. (Briophyta: Selaginellaceae). Larvae are solitary in all instars, presenting a color pattern and shape

5. Composition and structure of the frugivorous butterfly community (Lepidoptera: Nymphalidae) at the Serra Azul State Park (PESA), Mato Grosso, Brazil
ABSTRACT Due to the important ecological role of Nymphalidae as consumers of fermented fruits, excrement, exudates of decomposed plants and animals, as well as bioindicators of environmental quality that attract the interest of the general public, this study aimed to characterize the fauna of frugivorous butterflies at the Serra Azul State Park - PESA (Mato

6. Butterflies (Lepidoptera: Papilionoidea) from the campos rupestres of Serra de São José, Minas Gerais, Brazil
Resumo Fornecemos o primeiro levantamento de espécies de borboletas (Lepidoptera: Papilionoidea) da Serra de São José, Minas Gerais, Brazil. A Serra de São José possui elevações variando de 800 a 1.400 m de altitude, onde as borboletas foram amostradas utilizando armadilhas e redes entomológicas em sete áreas ao longo do gradiente altitudinal.

7. Butterfly fauna (Lepidoptera, Papilionoidea) in a heterogeneous area between two biodiversity hotspots in Minas Gerais, Brazil
Abstract This paper investigates the butterfly fauna of the ‘Serra do Rola-Moça’ State Park, Minas Gerais, Brazil. We evaluate i) the seasonal variation of species richness and composition; and ii) the variation in composition of the local butterfly assemblage among three sampling sites and between the dry and rainy seasons. Sampling was carried out mon

8. The Modification of (Nd0.5Ta0.5)4+ Complex-Ions on Structure and Electrical Properties of Bi0.5Na0.5TiO3-BaTiO3 Ceramics
The (Bi0.5Na0.5)0.94Ba0.06Ti1-x (Nd0.5Ta0.5) xO3 (0.01≤x≤0.05) lead-free ceramics (BNBT-xNT) used (Nd0.5Ta0.5)4+ complex-ions to modify its structure and electrical properties. The BNBT-xNT ceramics exhibit the coexistence of tetragonal and rhombohedral phase. The (Nd0.5Ta0.5)4+ complex-ions prohibit grain growth, and its average grain size decreases fro

9. Retinal dystrophies and variants in PRPH2
RESUMO | Este relato apresenta três pacientes com diagnóstico de distrofias maculares com mutações no PRPH2. Periferina 2, a proteína deste gene, é importante na morfogênese e estabilização do segmento externo dos fotorreceptores. Deficiências de periferina 2 causam apoptose celular. Além disso, variantes patogênicas no PRPH2 estão relacionadas

10. Butterflies (Lepidoptera: Papilionoidea) of an urban park in northeastern Brazil
Resumo Apesar de ser um dos grupos mais bem estudados no Brasil, as borboletas da região Nordeste, especialmente ao norte da foz do Rio São Francisco, são ainda pouco conhecidas. O objetivo deste estudo foi realizar um inventário da fauna de borboletas em um fragmento de Floresta Atlântica no estado de Pernambuco, como uma contribuição para compreens�

11. A remarkable new species of Phocides (Lepidoptera: Hesperiidae) from Bolivia and taxonomic considerations on Phocides charon
ABSTRACT A new skipper butterfly, Phocides petroleum Siewert, Leviski, Mielke & Casagrande sp. nov. is described and illustrated from Caranavi, La Paz Department, Bolivia. The new species seems closely related to Phocides charon (C. Felder & R. Felder, 1859) but could be easily distinguished by a set of external characteristics. Lectotypes are designated for

12. Before it is too late: description of a new genus and species of butterfly from a highly threatened Brazilian biome
Abstract A new genus, Nhambikuara Freitas, Barbosa & Zacca gen. nov., and species, Nhambikuara cerradensis Freitas, Barbosa & Zacca sp. nov., of the highly diverse Neotropical butterfly subtribe Euptychiina are described. Nhambikuara cerradensis sp. nov. is the type species for the genus, and Euptychia mima Butler, 1867 is also transferred to the new genus,
