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

Physiological Entomology, Volume 50, Issue 2, Page 152-165, June 2025.
Leafcutter ants show a high degree of task division among the workers of different castes. For example, the smallest workers, the minims, care for the brood and the symbiotic fungus, whereas the larger mediae cut and transport plant material.

Cretaceous lacewing larvae with binocular vision demonstrate the convergent evolution of sophisticated simple eyes. [PDF]

Insect Sci
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.

Morphological adaptations of the mouthparts to the ectoparasitic lifestyle of the biting midge Forcipomyia paludis (Diptera: Ceratopogonidae), specialized in Odonata [PDF]

, 2022
Damselflies and dragonflies are well-known hosts of the West Palaearctic biting midge Forcipomyia paludis. Females of this ectoparasitic dipteran mainly cling to the host’s wings, sucking hemolymph from the wing veins.

Morphological evolution and phylogeny of millipedes (Diplopoda) [PDF]

, 2023
Millipedes (Diplopoda) count more than 12,000 described species and play, probably since more than 400 million years, a fundamental role as detritivores in terrestrial ecosystems.

Wonderfully weird: the head anatomy of the armadillo ant, Tatuidris tatusia (Hymenoptera: Formicidae: Agroecomyrmecinae), with evolutionary implications [PDF]

, 2023
Tatuidris tatusia Brown & Kempf, 1968, the armadillo ant, is a morphologically unique species found in low to high elevation forests in regions of Central and South America. It is one of only two extant representatives of the subfamily Agroecomyrmecinae,

Morphological Disparity of the Mouthparts in Polyphagous Species of Largidae (Heteroptera: Pentatomomorpha: Pyrrhocoroidea) Reveals Feeding Specialization [PDF]

, 2020
Mouthpart structures were observed in four species of Largidae using scanning electron microscopy to investigate their morphological disparity, and linked to changes in feeding specialization.

Comparative morphology of the larval mouthparts among six species of Notodontidae (Insecta, Lepidoptera), with discussions on their feeding habits and pupation sites [PDF]

, 2023
Larval mouthparts are significant organs for the individual development, morphologically related with feeding habits, and providing valuable characters for taxonomy and phylogenetic analysis.

Comparative morphology of the mouthparts of the megadiverse South African monkey beetles (Scarabaeidae: Hopliini): feeding adaptations and guild structure [PDF]

, 2016
Although anthophilous Coleoptera are regarded to be unspecialised flower-visiting insects, monkey beetles (Scarabaeidae: Hopliini) represent one of the most important groups of pollinating insects in South Africa’s floristic hotspot of the Greater Cape ...

The Early Evolution of Biting–Chewing Performance in Hexapoda [PDF]

, 2019
Insects show a plethora of different mandible shapes. It was advocated that these mandible shapes are mainly a function of different feeding habits.
