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

open access: yesInsect Science, Volume 33, Issue 4, Page 1256-1284, August 2026.
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 ...

The cost of parental care: prey hunting in a digger wasp [PDF]

open access: yesBehavioral Ecology, 2002
Trivers's concept of parental investment is an integral part of modern evolutionary biology. "Parental investment" is defined as any parental expenditure that benefits a current progeny at the expense of a parent's ability to reproduce in the future. Because future costs are hard to quantify, other currencies were used that were thought to be related ...

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

open access: yesAdvanced Science, Volume 13, Issue 39, 13 July 2026.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Gene Expression and Alternative Splicing Regulate Phenotypic Plasticity of a Social Wasp

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
This study demonstrates that patterns of differential gene expression and alternative splicing are partially linked in a social wasp. In addition, colony‐level environmental variation drives far stronger transcriptomic divergence than genetic differences, highlighting that social environment plays a strong role in shaping developmental plasticity ...

Beyond the treeline: Are wood‐nesting bees and wasps limited by nesting habitat at high elevations?

open access: yesEcology, Volume 107, Issue 7, July 2026.
Abstract Although climate suitability is often thought to be the most important determinant of species ranges, non‐climate variables such as biotic interactions, dispersal abilities, and habitat quality may play equally important roles as range‐limiting factors.

Morphological distance and inter-nest distance account for intra-specific prey overlap in digger wasps (Hymenoptera: Crabronidae) [PDF]

open access: yes, 2012
Although inter-individual diet variation is common in predatory wasp populations, the factors accounting for such variation are still largely unknown.

Spatial nest-settlement decisions in digger wasps: Conspecifics matter more than heterospecifics and previous experience [PDF]

open access: yes, 2015
Research into the driving forces behind spatial arrangement of wasp nests has considered abiotic environmental factors, but seldom investigated attraction or repulsion towards conspecifics or heterospecifics.

Progressive Cellularization of Blastoderm and Extraembryonic Tissue Formation in the Ant Camponotus floridanus

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 5, Page 411-421, July 2026.
Illustration of the process of cellularization in Camponotus floridanus (top row) compared to Drosophila melanogaster (bottom row). Progressive direct formation of differentiating blastoderm mode is depicted using hexagons that represent energids (without borders) and cells (with borders). Colors of nuclei represent different cell types.

Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages

open access: yesJournal of Animal Ecology, Volume 95, Issue 7, Page 1207-1219, July 2026.
By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering
