Description of the Nymph of Enallagma minusculum (Odonata: Coenagrionidae)

The Florida Entomologist, 1975
The nymph of Enallagma minusculum Morse is described from reared specimens collected at White Lake, North Carolina. It differs from all other described North American Enallagma nymphs in that the gill tips are rounded.

The impact of climate-induced distributional changes on the validity of biological water quality metrics [PDF]

, 2010
We present data on the distributional changes within an order of macroinvertebrates used in biological water quality monitoring. The British Odonata (dragonflies and damselflies) have been shown to be expanding their range northwards and this could ...

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

Insect Conservation and Diversity, EarlyView.
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.

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

EntomoBrasilis, 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 ...

A Preservative-Free Emergent Trap for the Isotopic and Elemental Analysis of Emergent Insects From a Wetland System [PDF]

, 2018
This study reports a cost-effective, live emergent trap designed for the preservative-free use in both biogeochemical and ecological analyses of emerging insects. The trap proved to be advantageous in several ways.

Does behaviour matter? The role and feasibility of research into arthropod behavioural syndromes to inform invertebrate translocation efforts

Insect Conservation and Diversity, EarlyView.
Animal personality plays a key role in translocation success in both wild‐to‐wild and captive‐to‐wild translocations, with important implications for the success of conservation projects. However, the majority of studies so far have explored the link between personality and translocation success in vertebrate translocations, and there has been less ...

New records of Coenagrion ornatum in Italy (Odonata: Coenagrionidae)

Fragmenta Entomologica, 2016
<em>Coenagrion ornatum</em> (Sélys, 1850) is a damselfly ranging from northwestern Europe to southwestern Asia. It is highly local, and northwestern populations are experiencing a steep decline. In Europe, <em>Coenagrion ornatum</em> is a species of conservation interest and is listed as Near Threatened due to habitat loss; it ...

Field estimates of reproductive success in a model insect: behavioural surrogates are poor predictors of fitness [PDF]

, 2011
Understanding, and therefore measuring, factors that determine fitness is a central problem in evolutionary biology. We studied a natural population of Coenagrion puella (Odonata: Zygoptera) over two entire breeding seasons, with over a thousand ...

Length–Dry Mass Relationships of Aquatic Insects: Geographic and Taxonomic Variation in a Digital Database

Freshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Aquatic insects are an abundant, yet declining, taxonomically heterogeneous group with special importance in both aquatic and terrestrial ecosystems. Accurate estimations of insect biomass during their aquatic life stages are essential to advance our fundamental knowledge about insects, their roles in ecosystems, and their vulnerability to ...

The genome sequence of the blue-tailed damselfly, Ischnura elegans (Vander Linden, 1820) [version 1; peer review: 2 approved]

Wellcome Open Research, 2022
We present a genome assembly from an individual female Ischnura elegans (the blue-tailed damselfly; Arthropoda; Insecta; Odonata; Coenagrionidae). The genome sequence is 1,723 megabases in span. The majority of the assembly (99.55%) is scaffolded into 14
