Recent studies have introduced computer tomography (CT) as a tool for the visualisation and characterisation of insect architectures. Here, we use CT to map the three-dimensional networks of galleries inside Cubitermes nests in order to analyse them with tools from graph theory. The structure of these networks indicates that connections inside the nest are rearranged during the whole nest life. The functional analysis reveals that the final network topology represents an excellent compromise… 
Self-Organized Linear and Helicoidal Ramps in Insect Nests
TLDR
3D model of nest building in Lasius niger ants is shown to be capable of producing layered structures with vertical helices similar to the structures built by Apicotermes by simply running it with parameters different from those empirically measured for ants.
Exploring nest structures of acorn dwelling ants with X-ray microtomography and surface-based three-dimensional visibility graph analysis
TLDR
A surprisingly high surface area and degree of spatial heterogeneity within the acorn nests of Temnothorax colonies, and specific regions, such as those associated with the locations of queens and brood, were significantly more conducive to connectivity than others.
Exploring nest structures of acorn dwelling ants with x-ray microtomography and surface based 3D visibility graph analysis
The physical spaces within which organisms live affect their biology and in many cases can be considered part of their extended phenotype. The nests of social insect societies have a fundamental
Wood anatomical selectivity of drywood termite in the nest-gallery establishment revealed by X-ray tomography
TLDR
The results indicated that drywood termites exhibited continual adaptation to their environment as well as self-organization, similar traits of foraging and nesting biology can also be found in intermediate and separate nesters, however, at a different ecological scale.
Wood excavation, construction, and architecture in two Reticulitermes subterranean termites
TLDR
Using computerized tomography scans and medical imaging software (OsiriX), nest creation, constructions, and architecture of two subterranean termite species are observed and some structures changed over time and thus might play a role in the trade-off between wood consumption, colony protection, and environmental homeostasis.
X-ray tomographic analysis of the initial structure of the royal chamber and the nest-founding behavior of the drywood termite Incisitermes minor
TLDR
The study revealed that the drywood termite engages in outside foraging activity and has great foraging flexibility and computer tomographic images revealed that I. minor reproductives showed anatomical selectivity in their nest-founding activity.
Network-based model of the growth of termite nests.
TLDR
The model based on the empirical analysis of the real nest networks combined with pruning, edge removal and a memory effect successfully predicts emergent nest properties and indicates that Termitinae networks favor fast internal transportation over efficient defense strategies against ant predators.
Volume Visualization of Hidden Gallery System of Drywood Termite Using Computed Tomography: A New Approach on Monitoring of Termite Infestation
In recent years, X-ray computed tomography (CT) has been developed as a reliable indirect method for insect studies. Here, we introduce the 3D volume visualization of hidden gallery system of drywood
Morphogenesis of an extended phenotype: four-dimensional ant nest architecture
TLDR
This study used micro-computed tomography scanning and time-series experiments to obtain the first high-resolution dataset on the four-dimensional growth of ant nests, showing that extrinsic features within the environment, such as the presence of planes between layers of sediment, influence the architecture of Lasius flavus nests.
When social behaviour is moulded in clay: on growth and form of social insect nests
TLDR
This work reviews present knowledge of the mechanisms of nest construction, and how nest structure affects the behaviour of individual insects and the organisation of activities within a colony.

Excavation and architecture of Argentine ant nests
TLDR
Analysis of nest structures in small sand-filled nest boxes by Argentine ant colonies found that excavation rates and final nest sizes increased with colony size, but were not tenfold greater in 1000-worker colonies than in 100- worker colonies.
Structures ≪atypiques≫ dans les nidifications souterrainesd'Apicotermes Lamani Sj. (Isoptera, Termitidae) misses en évidence par la radiographie
TLDR
The authors attribute certain distinctions in the manner of construction in different types of nest to an evolutionary character: “perfectionnement” by the more complex development of simpler (more primitive) arrangements, differenciation, regression by loss of function, etc.
The growth and form of tunnelling networks in ants.
TLDR
This work used a standardized two-dimensional set-up shaped as a disk and studied the characteristics of tunnel growth in terms of initiation, propagation and termination of new digging sites and found that they can be described with simple probabilistic laws.
A new technique for termite monitoring using computer tomography and endoscopy
TLDR
Two techniques used in the medical sector – endoscopy and computer tomography – are combined to directly observe the nest construction behaviour of one pest species, Cryptotermes secundus Hill (Kalotermitidae), within soft wood, and could help to continuously monitor wood consumption rates of termite colonies.
Nest architecture of the ant Formica pallidefulva: structure, costs and rules of excavation
TLDR
The architecture of underground ant nests was studied in the ant Formica pallidefulva, which consist of more or less vertical shafts that bear chambers, which are top-heavy and declining exponentially with depth.
Ants Inhabiting Cubitermes Termitaries in African Rain Forests1
TLDR
The results imply that in the rain forest the scarcity of nesting sites is one of the principal factors limiting the populations of ground-dwelling ants.
The architecture of termite mounds: a result of a trade-off between thermoregulation and gas exchange?
TLDR
A model is presented that illustrates this trade-off between thermoregulation and gas exchange under different temperature regimes that result in different mound architectures under different environmental temperatures and may finally limit the distribution of this species.
The nest architecture of the Florida harvester ant, Pogonomyrmex badius
TLDR
The architecture of the subterranean nests of the Florida harvester ant, Pogonomyrmex badius, was studied through excavation and casting and it was found that older workers moved upward to assume positions in the upper parts of the nest, much as in the colonies from which they were taken.
Efficiency and robustness in ant networks of galleries
TLDR
It is shown that the networks of galleries have a path system efficiency and robustness to disconnections closer to the one observed in triangulated networks though their cost is closer tothe one of a tree.
Cubitermes subarquatus termitaries as shelters for soil fauna in African rainforests
TLDR
Work carried out in five forests in southern Cameroon indicates that termitaries of Cubitermes subarquatus, whether active or abandoned, provide shelter for large numbers of invasive invertebrates, particularly ants and other termite species, and may be a determining factor in the patchy distribution of many taxa.
