The complete mitochondrial genome of Sympetrum striolatum (Odonata: Libellulidae) and phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2020
Here, we sequenced and annotated the complete mitogenome of Sympetrum striolatum (Odonata: Libellulidae). This mitogenome is 15,435 bp in length, consisting of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA unit genes, and

Integrating eDNA and community science to monitor urban Odonata diversity

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 84-92, January 2026.
Environmental DNA captured rare and underrepresented taxa often missed by community science observations. Community science revealed adult‐stage observations across a broader temporal window. Integrating both methods improved detection across life stages, seasons, and species prevalence.

Quantitative Metabarcoding Reveals the Effects of Ecological Factors and Invasive Species on Functional Diversity of Freshwater Insects

open access: yesMolecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Aquatic insects are the most biodiverse freshwater animals. DNA metabarcoding data are increasingly used to assess variation in insect communities, but they are rarely integrated with information on the abundance or biomass of different taxa that can provide key insights into their functional responses.

Population structure and speciation in the dragonfly Sympetrum striolatum/nigrescens (Odonata: Libellulidae): An analysis using AFLP markers

open access: yesEuropean Journal of Entomology, 2009
There has been a long-standing debate as to whether Sympetrum striolatum (Charpentier, 1840) and the darker northern form, S. nigrescens (Lucas, 1912) should be recognised as separate species of dragonfly.

Observations on the Nesting of \u3ci\u3eCrabro Tenuis\u3c/i\u3e (Hymenoptera: Sphecidae) [PDF]

open access: yes, 2017
Three nests of Crabro tenuis were studied during June 1971-1972 in Oswego County, New York. Females constructed shallow but lengthy, multicelled nests in sand with the cells being built in clusters, sometimes in series. Females plugged the entrances with

Diversification and evolution of Hawaiian Megalagrion damselflies (Pinapinao, Odonata: Coenagrionidae) Ka Ho‘omāhuahua a me ke Kumu Ho‘omohala o nā Pinapinao Megalagrion o Hawai‘i (Odonata: Coenagrionidae)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
The ancestor of today's pinapinao, Hawaiian Megalagrion damselflies, diverged from Ischnurinae around 51 MA and likely evolved for over 20 MA before colonizing the Northwestern Hawaiian Islands. An ancestor of Megalagrion colonized the Northwestern Hawaiian Islands and diversified into ecological niches with four new breeding habitats and two new gill ...
