13. Association between molecular markers and behavioral phenotypes in the immatures of a butterfly
Abstract Newly hatched caterpillars of the butterfly Heliconius erato phyllis routinely cannibalize eggs. In a manifestation of kin recognition they cannibalize sibling eggs less frequently than unrelated eggs. Previous work has estimated the heritability of kin recognition in H. erato phyllis to lie between 14 and 48%. It has furthermore been shown that the

14. Effects of changes in the riparian forest on the butterfly community (Insecta: Lepidoptera) in Cerrado areas
ABSTRACT Preserved riparian vegetation usually has greater environmental complexity than the riparian vegetation modified by human actions. These systems may have a greater availability and diversity of food resources for the species. Our objective was to evaluate the effect of changes on the structure of the riparian forest on species richness, beta diversi

15. First host plant record for Strymon davara (Hewitson) (Lepidoptera, Lycaenidae) in the highly human-modified coastal valleys of the Atacama Desert
ABSTRACT Some native plants can survive the disturbances associated with agricultural activities, sometimes being considered weeds and objects of control practices. However, these plants can be very important to support populations of native insects in disturbed habitats. Alternanthera halimifolia (Lam.) Standl. (Amaranthaceae) is locally considered a weed,

16. 'Species' from two different butterfly genera combined into one: description of a new genus of Euptychiina (Nymphalidae: Satyrinae) with unusually variable wing pattern
ABSTRACT Sepona Freitas and Barbosa, gen. nov. is proposed for the Neotropical satyrine butterfly species Euptychia punctataWeymer, 1911 and its junior subjective synonyms Euptychia griseolaWeymer, 1911 and Taygetis indecisa Ribeiro, 1931. The new genus has a distinctive wing pattern and shape of the valvae in the male genitalia, the latter being a unique au

17. Stichelia pelotensis (Lepidoptera, Riodinidae): conservation, notes, and rediscovery of an endangered butterfly from southern Brazil
ABSTRACT Stichelia pelotensis (Lepidoptera, Riodinidae) is an endemic and threatened butterfly from the Pampa biome in southern Brazil, and has not been recorded in its type locality in the last 56 years. Recently, a population was found in two sites from extreme south Brazil, Pelotas, Rio Grande do Sul state. These records are an important find given the co

18. Hydrothermal Synthesis of Three-dimensional Butterfly-like Ni Architectures as Microwave Absorbers
AbstractThree-dimensional butterfly-like Ni architectures were fabricated by a surfactant-assisted hydrothermal method. The Ni architectures, with lengths of about 20 μm and widths of 4-6 μm, were assembled from tens of Ni nanorods with the averaged diameter of about 200 nm. The Ni nanorods were coated by oxide shells. The saturation magnetization of the N

19. The taxonomic identity of Heliconius melpomene f. pyritosa var. fumigata Zikán (Lepidoptera: Nymphalidae)
The taxonomic identity of the butterfly Heliconius melpomene f. pyritosa var. fumigata Zikán, 1937 (Nymphalidae: Heliconiinae) is discussed based on the discovery of the specimen based on which this name was assigned. The specimen is not a variation of Eueides tales surdus Stichel, 1903, as previously stated, but is in fact a variation of H. melpomene f. py

20. External morphology of the immature stages of Neotropical heliconians: IX. Dione glycera (C. Felder & R. Felder) (Lepidoptera, Nymphalidae, Heliconiinae)
External morphology of the immature stages of Neotropical heliconians: IX. Dione glycera (C. Felder & R. Felder) (Lepidoptera, Nymphalidae, Heliconiinae). The biology of the Andean silverspot butterfly Dione glycera (C. Felder & R. Felder, 1861) is still poorly known. This species is restricted to high elevations in the Andes, where the immature stages are f

21. Latitudinal gradient effect on the wing geometry of Auca coctei (Guérin)(Lepidoptera, Nymphalidae)
Latitudinal gradient effect on the wing geometry of Auca coctei (Guérin) (Lepidoptera, Nymphalidae). When the environmental conditions change locally, the organisms and populations may also change in response to the selection pressure, so that the development of individuals may become affected in different degrees. There have been only a few studies in whic

22. Influência da agregação larval na história de vida de Ascia monuste orseis (Godart, 1819) (Lepidoptera, Pieridae) / Influence of larval aggregation on life-history traits of Ascia monuste orseis (Godart, 1819) (Lepidoptera, Pieridae)
In insects, the gregarious habit has been shown to improve foraging and defense against predation to both larval and adult stages. Egg clusters could also be beneficial through increased larval hatching. In this study, we tested the hypothesis that egg clusters and larval aggregations of the neotropical butterfly Ascia monuste orseis (Godart, 1819) (Pieridae

23. Filogenia e biogeografia das espécies de actinote hübner, 1819 (Nymphalidae : Heliconinae) / Phylogeny and biogeography of species of actinote hübner, 1819 (Nymphalidae : Heliconinae)
Many aspects and details of the origin, evolution and biogeographical patterns of butterflies are not yet fully comprehended. The phylogenetic relationships among most butterfly groups remained unknown until recently. Phylogenetic studies have been based mainly on morphological characters of adults, although characters of immature stages had increased in use

24. A influência de palmares e parachute na coordenação dos nados / Effect of hand paddles and parachutes on swimming coordination
A natação é uma modalidade esportiva que, ao longo dos anos, sofreu modificações, atingindo um alto nível de exigência, o que é refletido nas sessões de treinamentos e nas pesquisas sobre a modalidade. Sendo assim, para otimizar o deslocamento nos nadadores pode-se otimizar a força propulsora. Para isso, pode-se utilizar palmares e parachute. Os pa
