Insect appendages and comparative ontogenetics [PDF]

, 2005
It is arguable that the evolutionary and ecological success of insects is due in large part to the versatility of their articulated appendages. Recent advances in our understanding of appendage development in Drosophila melanogaster, as well as ...

Cretaceous lacewing larvae with binocular vision demonstrate the convergent evolution of sophisticated simple eyes

Insect Science, EarlyView.
We report three ca. 100 million‐year‐old lacewing larvae with extraordinarily large stemmata. One of them additionally has a very wide head, which represents a previously unknown morphology. The arrangement of the stemmata indicates stereoscopic vision in these predatory larvae.

New extreme morphologies as exemplified by 100 million-year-old lacewing larvae [PDF]

, 2021
Larvae of the group Holometabola (beetles, wasps, flies, moths and others) differ significantly in their morphology from their corresponding adults. In most larvae, appendages and other structures protruding from the body (antennae, palps, legs, trunk ...

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

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, EarlyView.
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 ...

Evolutionary implications of a deep‐time perspective on insect pollination

Biological Reviews, EarlyView.
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.

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

Systematic 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)

Physiological 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)

Journal 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.
