Small whiteface (Leucorrhinia dubia: Odonata) reintroduction update highlights the importance of long‐term monitoring and regular habitat management

Insect Conservation and Diversity, Volume 18, Issue 5, Page 859-868, September 2025.
In 2001, 80 larvae of Leucorrhinia dubia were translocated from degraded raised bog in Slovakia to the newly created peatbog pools in Czechia, and the population has been regularly monitored. Based on the capture‐mark‐recapture and exuviae surveys in 2015 and 2024, the population size is stable, comprising ca.

Assessing predation pressure of Vespa velutina on local fauna through DNA metabarcoding

Journal of Zoology, Volume 326, Issue 4, Page 329-338, August 2025.
This study investigates the predation pressure exerted by the invasive yellow‐legged hornet (Vespa velutina) on native insect populations in Mallorca, using DNA metabarcoding to analyze their diet. Results reveal a diverse prey spectrum, including key insect groups such as Apidae (bees), Calliphoridae (blowflies), and Vespidae (wasps), with no ...

Thermal Plasticity in a Cross‐Sexual Transfer Trait: Geographic Variation and Phenotypic Integration of Blue Wing Colour in Female Butterflies [PDF]

Ecol Lett
We provide a first test whether female colour variation in common blue butterflies (a) has arisen through cross‐sexual transfer. Analyses of museum specimens (b) show that the distribution of females wing colour varies in a geographic mosaic pattern, and laboratory experiments (c) show that this variation is both genetically determined and impacted by ...

The potential contribution of flood management ponds to pondscape biodiversity: Evidence from dragonflies

Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
The creation of ponds to alleviate the impacts of floods has the potential to support freshwater biodiversity. Our study investigates the ecological value of ponds created for Natural Flood Management as part of the Eddleston Water Project, in the Scottish Borders (UK).

Scientists' warning on the need for greater inclusion of dragonflies in global conservation

Insect Conservation and Diversity, Volume 18, Issue 4, Page 465-484, July 2025.
Stressors to dragonflies are multiple, and in many cases interactive. Specialist species are at risk, while generalists can benefit from some human activities. Dragonflies are sentinels for conservation, being promising surrogates for other taxa while also being appealing to citizen science initiatives.

Effects of the pyrethroid insecticide gamma-cyhalothrin on aquatic invertebrates in laboratory and outdoor microcosm tests [PDF]

The sensitivity of a range of freshwater lentic invertebrates to gamma-cyhalothrin (GCH), a single enantiomer of the synthetic pyrethroid lambda-cyhalothrin, was assessed in single species laboratory tests and an outdoor multi-species ecosystem test. The

Coloration in Argia damselflies of Central Mexico responds to changes in herbaceous vegetation La coloración de caballitos del diablo del género Argia responde a cambios en la cobertura de vegetación herbácea en el Centro de México

Insect Conservation and Diversity, Volume 18, Issue 4, Page 593-603, July 2025.
The increase in urban lands and the vegetation loss implies changes in the colour of the background which in turn could cause changes in the coloration of individuals. We measured changes in body lightness of damselflies through 19 sites in Central Mexico, with a different degree of urbanisation and a different percentage of native vegetation. We found
