Combining simplicity and functionality: mouthpart sensilla in the miniature parasitoid wasp Megaphragma viggianii (Hymenoptera, Trichogrammatidae) [PDF]

Insects depend on complex sensory systems to detect food sources, locate mates, and navigate in the environment. In the smallest insects, miniaturization imposes major constraints on anatomy and physiology, but it remains poorly understood how this ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

The insect head rewound: Clarifications to the groundplan of Hexapoda (Pancrustacea) [PDF]

The organization of the hexapod head remains a cornerstone problem in arthropod systematics, central to segmental homology, character definition, higher-level phylogeny, and functional and evolutionary morphology.

Functional morphology of the raptorial forelegs in Mantispa styriaca (Insecta: Neuroptera) [PDF]

, 2021
The insect leg is a multifunctional device, varying tremendously in form and function within Insecta: from a common walking leg, to burrowing, swimming or jumping devices, up to spinning apparatuses or tools for prey capturing.

Ecological factors underlying the spatiotemporal dynamics in a key forest beetle pollinator Facteurs écologiques à la base de la dynamique spatio‐temporelle d'un important coléoptère forestier pollinisateur

Agricultural and Forest Entomology, Volume 27, Issue 4, Page 590-599, November 2025.
Eusphalerum, an understudied beetle pollinator in North America, comprises over 50% of beetle specimens collected using flight‐intercept traps in forests across New Brunswick, Canada. In a study investigating its phenology, congeneric aggregation and population dynamics, we demonstrated that Eusphalerum exhibits unique phenology distinct from other ...

The Paragenital Organ of Stylopidae (Insecta: Strepsiptera) and the Functional Incorporation of the Secondary Larval Exuvia

Journal of Morphology, Volume 286, Issue 9, September 2025.
In the insect order Strepsiptera, we identified a paragenital organ in the family Stylopidae that serves as a secondary genital organ for traumatic insemination. We show that the cuticle at the penetration sites is thickened in all species studied, relative to control sites.

Consumer or Decomposer? Behavioral and Morphological Diagnosis of White Grubs

Ecology 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

Biological 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

Ecology 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]

, 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.
