Density‐dependent sex‐biased development of macroptery in a water strider [PDF]

open access: yesEcology and Evolution, 2020
In wing‐polymorphic insects, wing morphs differ not only in dispersal capability but also in life history traits because of trade‐offs between flight capability and reproduction. When the fitness benefits and costs of producing wings differ between males

To fly or not to fly: Factors influencing the flight capacity of carabid beetles (Coleoptera: Carabidae) [PDF]

open access: yesEuropean Journal of Entomology, 2016
This review considers factors affecting the flight capacity of carabid beetles and the implications of flight for carabids. Studies from the Dutch polders in particular show that young populations of carabids consist predominantly of macropterous species

The planthopper genus Spartidelphax, a new segregate of Nearctic Delphacodes (Hemiptera, Delphacidae). [PDF]

open access: yesZookeys, 2014
The new genus Spartidelphax is described to house three species removed from the polyphyletic genus Delphacodes. The members of Spartidelphax are coastal species native to eastern North America, and probably feed exclusively on cordgrass (Poaceae ...

Inclusion of rare taxa from Blattidae and Anaplectidae improves phylogenetic resolution in the cockroach superfamily Blattoidea

open access: yesSystematic Entomology, Volume 48, Issue 1, Page 23-39, January 2023., 2023
1. Phylogeny reconstruction based on mitochondrial genomes provided a number of insights into the evolutionary history of Blattoidea. 2. A new subfamily and two synonyms were proposed in Blattidae: Hebardininae subfam. nov., Archiblattinae Kirby syn. nov. and Shelfordella Adelung syn. nov. 3.

Hay meadows' overriding effect shapes ground beetle functional diversity in mountainous landscapes

open access: yesEcosphere, Volume 13, Issue 8, August 2022., 2022
Abstract Mountain regions are hotspots of biodiversity, and are particularly sensitive to human activities and global changes. Characterizing biodiversity using trait‐based approaches may improve the understanding of the evolutionary and mechanistic basis of ecological patterns in species distribution.

Experimental evidence for density-determined wing dimorphism in two bush-crickets (Ensifera: Tettigoniidae)

open access: yesEuropean Journal of Entomology, 2009
Macroptery is common in many species of Orthoptera, but the causes are still discussed. Besides the assumption that macroptery is genetically determined, there is evidence that wing dimorphism is induced by environmental factors, particularly population ...

Ground Beetles From a Remnant Oak-Maple-Beech Forest and Its Surroundings in Northeastern Ohio (Coleoptera: Carabidae) [PDF]

open access: yes, 2017
We report 66 ground beetle species in 14 tribes from a natural preserve in northeastern Ohio (Stark County). Six species are new state records. Data from pitfall trap transects across adjoining habitats suggest narrow habitat preferences in some species ...

Ground Beetles of Islands in the Western Basin of Lake Erie and the Adjacent Mainland (Coleoptera: Carabidae, Including Cicindelini) [PDF]

open access: yes, 2017
We report 241 species representing 63 genera of ground beetles from the islands of the western basin of Lake Erie and selected mainland sites from a 1991-93 survey, plus specimens examined in public and private collections, and previously published ...
