Evolutionary implications of a deep‐time perspective on insect pollination

open access: yesBiological Reviews, Volume 100, Issue 4, Page 1452-1466, August 2025.
ABSTRACT Plant pollination by insects represents one of the most transformative and iconic ecological relationships in the natural world. Despite tens of thousands of papers, as well as numerous books, on pollination biology published over the past 200 years, most studies focused on the fossil record of pollinating insects have only been published in ...

Novel regulation of the homeotic gene Scr associated with a crustacean leg-to-maxilliped appendage transformation. [PDF]

open access: yes, 2014
Homeotic genes are known to be involved in patterning morphological structures along the antero-posterior axis of insects and vertebrates. Because of their important roles in development, changes in the function and expression patterns of homeotic genes ...

Niche Differentiation of Three Terrestrial Isopod Species Based on DNA Metabarcoding

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Species coexistence is a hot topic in ecology, with niche differentiation playing a key role in reducing interspecific competition. This study investigates the dietary habits and niche differentiation of three terrestrial isopod species (Armadillidium vulgare, Sphaeroma raffaelei, and Trachelipus semiproiectus) using DNA metabarcoding technology.

Entomo-venomics: the evolution, biology and biochemistry of insect venoms [PDF]

open access: yes, 2018
The insects are a hyperdiverse class containing more species than all other animal groups combined-many of which employ venom to capture prey, deter predators and micro-organisms, or facilitate parasitism or extra-oral digestion.

Gastritis over Gastrisus Sharp (Coleoptera: Staphylinidae: Xanthopygina): Resolving a major taxonomic impediment with phylogenomics

open access: yesSystematic Entomology, Volume 50, Issue 3, Page 449-468, July 2025.
Comprehensive phylogeny of Xanthopygina rove beetles (Coleoptera: Staphylinidae), including 30 of 33 genera, was generated by anchored hybrid enrichment of 1229 nuclear, protein‐encoding loci. We resolved nine major clades within Xanthopygina, including the new Leptodiastemus group, and successfully delineated a monophyletic concept of Gastrisus ...

Mechanical properties and cuticle organisation in mandibles are related to the task specialisation in leafcutter ants (Atta laevigata, Attini, Formicidae)

open access: yesPhysiological Entomology, Volume 50, Issue 2, Page 152-165, June 2025.
Task‐specialization and mandible properties: Leafcutter ants show caste‐based task division, reflected in mandible morphology and mechanical properties. Structural and mechanical analysis: The cuticle was composed of exo‐, meso‐, and endocuticle.

Embryonic Development of Appasus japonicus Vuillefroy, With Special Reference to Mouthparts Formation (Insecta: Heteroptera, Belostomatidae)

open access: yesJournal of Morphology, Volume 286, Issue 5, May 2025.
In this study, we provide a detailed description of the embryonic development of Appasus japonicus, focusing on the formation of its specialized mouthparts. We identify homologies between the maxillary plate and maxillary palp and most parts of the stylet‐like mandibles and maxillae are housed within the labial palp.

The structure of extremely long mouthparts in the aphid genus Stomaphis Walker (Hemiptera: Sternorrhyncha: Aphididae) [PDF]

open access: yes, 2015
Scanning electron microscopy and light microscopy were used to elucidate the morphology of labium and mandibular and maxillary stylets of the aphids Stomaphis quercus (L.) and S. graffii Cholodkovsky.

Interactions between host plant quality and non‐consumptive predator effects on oviposition and larval behaviour of Plutella xylostella (Lepidoptera: Plutellidae)

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 2, Page 148-159, May 2025.
Abstract The presence of predators can induce non‐consumptive effects on prey that result in subsequent changes to prey behaviour and defence. We investigate the interaction between top‐down non‐consumptive effects of various stages of the predator Coccinella septempunctata L.(Coleoptera: Coccinellidae) (larvae and adult) and bottom‐up effects of host ...

Morphological Variance in Mouthparts and Foraging Behavior in Bumblebees [PDF]

open access: yes, 2021
Bumblebees (Hymenoptera: Apidae: Bombus) show an incredible degree of size variation within and between species. Individuals from the same hive may vary up to 10-fold in mass.
