The behavioural demands of group living and foraging have been implicated in both evolutionary and plastic changes in brain size. Desert locusts show extreme phenotypic plasticity, allowing brain morphology to be related to very different lifestyles in one species. At low population densities, locusts occur in a solitarious phase that avoids other locusts and is cryptic in appearance and behaviour. Crowding triggers the transformation into the highly active gregarious phase, which aggregates…

The Neurobiology of a Transformation from Asocial to Social Life During Swarm Formation in Desert Locusts
There is emerging evidence that the neuronal mechanisms underlying this transformation in locusts show similarities with those underlying social behaviours in other animals, and this analysis of phase change provides insights into a feedback circuit between the environment and the neurobiology of social interaction.
Divergence in brain composition during the early stages of ecological specialization in Heliconius butterflies
It is demonstrated that the incipient species pair, Heliconius erato and H. himera, are parapatric across an environmental and altitudinal gradient, and that these taxa also differ significantly in brain composition, in particular in the relative levels of investment in structures that process sensory information.
Listening to the environment: hearing differences from an epigenetic effect in solitarious and gregarious locusts
The enhanced response to high-frequency sounds in the nocturnally flying solitarious locUSTs suggests greater investment in detecting the ultrasonic echolocation calls of bats, to which they are more vulnerable than diurnally active gregarious locusts.
Brain composition in Godyris zavaleta, a diurnal butterfly, Reflects an increased reliance on olfactory information
The results illustrate that ecological selection pressures mold the structure of invertebrate brains, and exemplify how comparative analyses across ecologically divergent species can illuminate the functional significance of variation in brain structure.
Brain composition in Heliconius butterflies, post-eclosion growth and experience dependent neuropil plasticity
This analysis uncovers age-and experience-dependent post-emergence mushroom body growth comparable to that in foraging hymenoptera, but also identifies plasticity in several other neuropil.
Brain composition in Heliconius butterflies, posteclosion growth and experience‐dependent neuropil plasticity
The brain composition of two species of Heliconius butterflies is described, confirming a previous report of a striking volumetric expansion of the mushroom body, and exploring patterns of differential posteclosion and experience‐dependent plasticity between different brain regions.
Socially induced behavioural plasticity precedes pronounced epigenetic differentiation in the CNS of Desert Locusts
It is found that rearing the offspring of chronically crowded locusts in social isolation leads to a pronounced differentiation of the neuromethylome within an individual's life-time, suggesting that it serves to consolidate long-term phase state.
Epigenetics and locust life phase transitions
Accumulating evidence points towards a role for epigenetic regulation in locust phase polyphenism, and this is corroborated in the economically important locust species Locusta migratoria and Schistocerca gregaria.
Division of Labor in the Hyperdiverse Ant Genus Pheidole Is Associated with Distinct Subcaste- and Age-Related Patterns of Worker Brain Organization
These findings reveal striking levels of developmental plasticity and evolutionary flexibility in Pheidole worker neuroanatomy, supporting the hypothesis that mosaic alterations of brain composition contribute to adaptive colony structure and interspecific variation in social organization.
Developmental‐ and food‐dependent foraging transcript levels in the desert locust
Drastic changes in the environment during a lifetime require developmental and physiological flexibility to ensure animal survival. Desert locusts, Schistocerca gregaria, live in an extremely


Plasticity in the visual system is correlated with a change in lifestyle of solitarious and gregarious locusts.
This work analyzed in both phases the responses of an identified visual interneuron, the descending contralateral movement detector (DCMD), which responds to approaching objects, and demonstrated that habituation of DCMD is fivefold stronger in solitarious locusts.
Spatiotemporal receptive field properties of a looming-sensitive neuron in solitarious and gregarious phases of the desert locust.
The lobula giant movement detector and its postsynaptic target, the descending contralateral movement detector, which are visual interneurons that detect looming objects are used to analyze how differences in the visual ecology of the two phases are served by altered neuronal function.
Diet breadth and anti-predator strategies in desert locusts and other Orthopterans
It remains to be investigated whether density-dependent aposematism and changes in food selection toward chemical defense, play a role in phase change in other locust species.
Mechanosensory-induced behavioural gregarization in the desert locust Schistocerca gregaria
The data show for the first time that the gregarizing signal combines both exteroceptive and proprioceptive components, which travel in both nerves 5B1 and 5B2, and provides a powerful experimental method with which to elicit and study neuronal plasticity in this system.
Coevolution of generalist feeding ecologies and gyrencephalic mushroom bodies in insects.
It is shown that gyrencephalic mushroom bodies in generalist scarabs are not associated with an increase in the size of their primary input neuropil, the antennal lobe, or in the number of antennale lobe glomeruli but rather with an apparent increased in the density of calycal microglomeruli and the acquisition of calYcal subpartitions.
Analysis of phase-related changes in behaviour of desert locust nymphs
An assay is developed in which the behavioural responses of an individual locust to a group of conspecifics are used to derive an index representing the ‘behavioural phase status’ of that insect. The
Developmental changes in the structure and function of the central olfactory system in gregarious and solitary desert locusts
The data show that anatomical and physiological properties of the antennal lobe and its neurons to a large extent reflect the changes in olfactory guided behaviour during development and between phases.
Spatial scales of desert locust gregarization.
Computer simulations and a laboratory experiment are presented that show how differences in resource distributions, conspicuous only at small spatial scales, can have significant effects on phase change at the population level; local spatial concentration of resource induces gregarization.
Serotonin Mediates Behavioral Gregarization Underlying Swarm Formation in Desert Locusts
It is shown that serotonin, an evolutionarily conserved mediator of neuronal plasticity, is responsible for this behavioral transformation, being both necessary if behavioral gregarization is to occur and sufficient to induce it.
