The adult head of the annulipalpian caddisfly Philopotamus ludificatus McLachlan, 1878 (Philopotamidae), mouthpart homologies, and implications on the ground plan of Trichoptera

open access: yesArthropod Systematics & Phylogeny, 2015
Adult head structures of representatives of all major trichopteran lineages were examined by using a combination of well-established morphological techniques as histology, light microscopy, scanning electron microscopy, and micro-computed tomography in ...

Consumer or Decomposer? Behavioral and Morphological Diagnosis of White Grubs

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
Determining the ecological role of insect larvae is crucial for pest control and resource utilization, relying on effective behavioral or morphological identification traits. This study uses an improved six‐armed olfactometer to analyze the feeding habits of two sympatric white grubs and the correlated morphological traits, including the sensory ...

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 ...

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.

A unique case of commensalism: The beaver beetle Platypsyllus castoris (Leiodidae, Coleoptera) and its morphological adaptations [PDF]

open access: yes, 2022
Platypsyllus castoris is closely associated with beavers and displays a unique set of structural specializations. We document the morphology of adults with modern techniques, and interpret evolutionary changes linked with the specific life style.

Waptia fieldensis Walcott, a mandibulate arthropod from the middle Cambrian Burgess Shale

open access: yesRoyal Society Open Science, 2018
Waptia fieldensis Walcott, 1912 is one of the iconic animals from the middle Cambrian Burgess Shale biota that had lacked a formal description since its discovery at the beginning of the twentieth century.

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 ...

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 ...

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.
