International Biological Flora: Loranthus europaeus*

open access: yesJournal of Ecology, Volume 114, Issue 4, April 2026.
Loranthus europaeus is a deciduous hemiparasitic species native to Europe and western Asia, primarily parasitizing oaks. It forms xylem connections via haustoria, extracting water and nutrients while exhibiting high transpiration and low water‐use efficiency.

Jumping mechanisms in jumping plant lice (Hemiptera, Sternorrhyncha, Psyllidae) [PDF]

open access: yesJournal of Experimental Biology, 2012
SummaryJumping mechanisms and performance were analysed in three species of psyllids (Hemiptera, Sternorrhyncha) that ranged from 2 to 4 mm in body length and from 0.7 to 2.8 mg in weight. Jumping was propelled by rapid movements of the short hind legs that were only 10-20% longer than the other legs and 61-77% of body length.

Carboniferous fossils enlighten the systematics and evolution of Hemiptera

open access: yesPapers in Palaeontology, Volume 12, Issue 2, March/April 2026.
Abstract Fossils are witnesses to the evolutionary processes undergone by living lineages. The earliest occurrence of clades provides rich insights into the timing of diversification of lineages and better delimits the groups that compose them. Hemiptera are a remarkable order within the insects due to their high morphological and ecological diversity.

Exploring hymenopteran parasitoid communities and their hosts: A comparative study of farmland and semi‐natural ecotones with focus on pentatomoid bugs and their antagonists

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 1, Page 118-127, February 2026.
Farmland ecotones support high parasitoid diversity, despite lower arthropod richness compared to semi‐natural habitats. Farmland ecotones support high pentatomoid bug abundance, while pentatomoid parasitoids were equally abundant and diverse in both ecotones.

Structure of the ovary in Steingelia (Sternorrhyncha: Coccinea), and its phylogenetic implications

open access: yesArthropod Structure & Development, 2003
The paired ovaries of Steingelia gorodetskia are composed of about 100 telotrophic ovarioles devoid of terminal filaments (scale insect autapomorphy). In structure they resemble those of other scale insects, but differ in the following details: (a) all ovarioles develop synchronously, (b) they are suspended to the lateral oviducts by means of long ...

Plant diversification impact on the oviposition response of a predatory bug in a laboratory set‐up

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 1, Page 128-134, February 2026.
Orius majusculus laid nearly twice as many eggs in cages with two different crop species compared with a single species. Depending on crop species, O. majusculus utilised different plant structures for oviposition. Crop diversification supports reproduction, and thus, is likely to have a positive effect on O.
