Perilestes eustaquioi sp. nov. and new distributional records of Perilestidae (Odonata) in Brazil

open access: yesZoologia (Curitiba), 2015
Perilestes eustaquioi sp. nov. (holotype male deposited in ABMM collection) from the state of Bahia (municipality of Una), northeastern Brazil, is described and illustrated based on one male specimen. It differs from the other species of the genus mainly

A Bibliometric Analysis of the Global Research in Odonata: Trends and Gaps

open access: yesDiversity, 2022
Insects of the order Odonata have been used as indicators of environmental quality in different aquatic systems around the world. In this context, we conducted a bibliometric analysis to understand the general patterns of research on Odonata published in

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Do egg parasitoids increase the tendency of Lestes sponsa (Odonata: Lestidae) to oviposit underwater?

open access: yesEuropean Journal of Entomology, 2015
The selection of oviposition sites by insects can significantly affect egg mortality. Spreadwing damselflies (Odonata: Lestidae) predominantly lay their eggs in parts of plants growing above the surface of water and only occasionally also those parts ...

Pest‐preservation paradox among insects

open access: yesConservation Biology, EarlyView.
The pest‐preservation paradox is a non‐binary perspective that insects range from those that are harmful and requiring management on the one side, to those requiring conservation intervention on the opposite end of the spectrum. Importantly, the vast majority of insects occur somewhere in the center of the two extremes, and their position along the ...

The Great Dividing Range as a driver of genetic divergence in a low‐dispersing dragonfly

open access: yesEcological Entomology, EarlyView.
Population genomic analyses revealed low genetic differentiation and no discrete population structure across the Great Dividing Range, indicating widespread gene flow in Synthemis eustalacta. Genetic divergence was associated with environmental gradients, elevation and landscape resistance rather than geographic distance, supporting isolation by ...

INVENTORY OF DRAGONFLIES AND DAMSELFLIES (ODONATA) IN ANDALAS UNIVERSITY’S LIMAU MANIS CAMPUS COMPLEX, PADANG: USING PHOTOGRAPHICAL APPROACH

open access: yesJurnal Natural, 2018
Odonata, which consists of true dragonflies and damselflies, is considerably understudied in Sumatra, especially in West Sumatra region. While the campus area of Andalas University in Limau Manis provides many suitable habitats for dragonflies and ...

Dragonfly functional connectivity responses are dynamic relative to drought

open access: yesInsect Conservation and Diversity, EarlyView.
During drought, dragonfly species richness decreases. Yet, dragonfly assemblages show a higher propensity for dispersal during drought. Dispersal pathways vary among the wet and dry periods, and relative to temporal changes in the landscape. While some dragonfly species can traverse plantation compartments, conservation corridors facilitate functional ...

Dragonfly taxonomic and functional responses to urbanized streams in southeastern Europe, with management recommendations

open access: yesInsect Conservation and Diversity, EarlyView.
Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.

Mecistogaster linearis (Fabricius) (Odonata: Coenagrionidae): First Record from Mato Grosso do Sul State, Brazil

open access: yesEntomoBrasilis, 2016
Commonly called “helicopter damselflies”, Mecistogaster species (Coenagrionidae) are recognized by their large body size in comparison with other Odonata species, ability to flap both anterior and posterior wings in opposite directions, and preference ...
