The phylogenetic information carried by a new set of morphological characters in planthoppers : the internal mouthpart structures and test in the Cixiidae model (Hemiptera: Fulgoromorpha) [PDF]

open access: yes, 2013
Internal morphological structures of Cixiidae mouthparts are described and compared in various representatives of the Cixiidae and several other representatives of hemipterans.

Morphology and Material Composition of the Mouthparts of Stromatium unicolor Olivier 1795 (Coleoptera: Cerambycidae) for Bionic Application [PDF]

open access: yes, 2020
The novelty of this study is the deep analysis of the morphologic, geometric and mechanical performance of longhorn beetle larvae mouthparts. Furthermore, a metal nano identification of jaw reinforced parts was made.

Mandibular Structure, Gut Contents Analysis and Feeding Group of Orthopteran Species Collected from Different Habitats of Satoyama Area within Kanazawa City, Japan [PDF]

open access: yes, 2020
A study was conducted on assemblies of various orthopteran species from distinct habitats in the Satoyama region, Kanazawa City, Ishikawa Prefecture, Japan, and a total of 50 distinct orthopteran species were registered. These species were represented by

First Case of Dual Size Asymmetry in an Identical Arthropod Organ: Different Asymmetries of the Combative (Sexual) and Cutting (Non-Sexual) Parts of Mandibles in the Horned Stored-Product Beetle Gnatocerus cornutus (Fabricius, 1798)

open access: yesInsects, 2018
Although it is known that separate insect body structures may be asymmetrical within one species, the different functional asymmetries within a single organ as a result of differential selective regimes have not been described.

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

open access: yesInsect 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]

open access: yes, 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

open access: yesInsect 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 ...

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea).

open access: yesThe Anatomical Record
Insects process their food with their cuticle-based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary ...

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

open access: yesAgricultural 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 ...

Life in the Cambrian shallows: Exceptionally preserved arthropod and mollusk microfossils from the early Cambrian of Sweden

open access: yesGeology
Burgess Shale−type (BST) Lagerstätten record an exceptional variety of Cambrian soft-bodied fauna, yet these deposits are typically restricted to outboard depositional settings >1000 km from the paleocoastline.
