ABSTRACT. Behavioral ecology of Heteragrion consors Hagen (Odonata: Megapodagrionidae): a shade-seek Atlantic forest damselfly. The intensity of the inter and intra-sexual selection can affect male behavioral traits as territorial fidelity and aggressiveness allowing the existence of different strategies. However, its differential success could be affected by environmental -as the diel variation in temperature -and physiological constrains -as the variation in thermoregulatory abilities. In this context, we present a behavioral analysis of Heteragrion consors (Zygoptera, Megapodagrionidae) trying to characterize its mating system, diel activity pattern, temporal budget, territoriality and reproductive biology. These data were obtained based on field observations using the focal individual method and mark-recapture techniques in 120 m of a shaded Atlantic Forest stream in Brazil. The males of this species were territorial, varying in its local fidelity, while the females appear sporadically. Males were perched in the majority of the time, but were also observed in cleaning movements, longitudinal abdominal flexion, wing flexion and sperm transfer during perch. The males presented a perched thermoregulatory behavior related to an exothermic regulation. Foraging and agonistic interactions were rare, but dominate the other behavioral activities. Abdominal movements associated to long lasting copula pointed to the existence of sperm competition in this species. Males performed contact post-copulatory guarding of the females. These observations pointed to a non-resource mating system for this species.KEYWORDS. Mating systems; reproductive biology; temporal budget; thermoregulation; territoriality.RESUMO. Ecologia comportamental de Heteragrion consors Hagen (Odonata: Megapodagrionidae): uma libélula de áreas sombreadas da Floresta Atlântica. A intensidade de seleção inter e intra-sexual deve afetar características comportamentais dos machos como fidelidade a territórios e agressividade possibilitando a existência de diferentes estratégias. No entanto, seu sucesso diferencial pode ser afetado por restrições ambientais, como a variação da temperatura durante o dia; e fisiológicas, como a capacidade de termoregulação. Neste contexto, apresentamos os resultados de uma análise do comportamento de Heteragrion consors (Zygoptera, Megapodagrionidae) buscando caracterizar seu sistema de acasalamento, padrão de atividade diário, orçamento temporal, territorialidade e biologia reprodutiva. Essas informações foram obtidas por observação em campo a partir do método de indivíduo focal e pela técnica de marcação-recaptura em 120 m de um riacho predominantemente sombreado de Floresta Atlântica no Brasil. Os machos desta espécie foram territoriais com variação na fidelidade local, enquanto as fêmeas praticaram visitas esporádicas. Machos permaneceram pousados durante a maior proporção do tempo, mas foram observados realizando movimentos de limpeza, flexão longitudinal abdominal, flexão alar e transferência espermática durante o pouso. ...

“…In damselflies, color has many functions, the most important being sex recognition, courtship, and territory defense behavior [ 19 ]. In Chalcopteryx rutilans – a damselfly found in the Amazonian rain forest – those functions are performed by the male by displaying its strongly iridescent hind wings.…”

“…Fumagalli et al [ 12 – 15 ], and Riedel et al [ 16 ] developed several techniques of electrostatic force microscopy (EFM) to extract the relative permittivity at the nanoscale, allowing for new fields to be explored. Here we use EFM to map the relative permittivity of nanostructures within the wings of the Chalcopteryx rutilans damselfly [ 17 – 19 ]; nanostructures which make it a natural photonic crystal. We obtain quantitative information about the wing structure and its local relative permittivity values.…”

The aim of this work is to determine the varying dielectric constant of a biological nanostructured system via electrostatic force microscopy (EFM) and to show how this method is useful to study natural photonic crystals. We mapped the dielectric constant of the cross section of the posterior wing of the damselfly Chalcopteryx rutilans with nanometric resolution. We obtained structural information on its constitutive nanolayers and the absolute values of their dielectric constant. By relating the measured profile of the static dielectric constant to the profile of the refractive index in the visible range, combined with optical reflectance measurements and simulation, we were able to describe the origin of the strongly iridescent wing colors of this Amazonian rainforest damselfly. The method we demonstrate here should be useful for the study of other biological nanostructured systems.

“…The wings play an important role in their reproductive behavior. 9 C. rutilans has transparent anterior wings and brightly colored posterior wings, which give rise to its common name-the glitterwing. Female individual wings have a reddish color seen on both the dorsal (top) and ventral (bottom) sides of the wing.…”

The iridescent wings of the Chalcopterix rutilans damselfly (Rambur) (Odonata, Polythoridae) are investigated with focused ion beam/scanning electron microscopy, transmission electron microscopy, and time-of-flight secondary ion mass spectrometry. The electron microscopy images reveal a natural photonic crystal as the source of the varying colors. The photonic crystal has a consistent number and thickness (∼195 nm) of the repeat units on the ventral side of the wing, which is consistent with the red color visible from the bottom side of the wing in all regions. The dorsal side of the wing shows strong color variations ranging from red to blue depending on the region. In the electron microscopy images, the dorsal side of the wing exhibits varied number and thicknesses of the repeat units. The repeat unit spacings for the red, yellow/green, and blue regions are approximately 195, 180, and 145 nm, respectively. Three-dimensional analysis of the natural photonic crystals by time-of-flight secondary ion mass spectrometry reveals that changes in the relative levels of Na, K, and eumelanin are responsible for the varying dielectric constant needed to generate the photonic crystal. The photonic crystal also appears to be assembled with a chemical tricomponent layer structure due to the enhancement of the CHN species at every other interface between the high/low dielectric constant layers.
