In contrast to bird flocks, fish schools and animal herds, midge swarms maintain cohesion but do not possess global order. High-speed imaging techniques are now revealing that these swarms have surprising properties. Here, I show that simple models found on the Langevin equation are consistent with this wealth of recent observations. The models predict correctly that large accelerations, exceeding 10 g, will be common and they predict correctly the coexistence of core condensed phases…

Mechanical spectroscopy of insect swarms
TLDR
It is shown that laboratory midge swarms have emergent continuum mechanical properties, displaying a collective viscoelastic response to applied oscillatory visual stimuli that allows us to extract storage and loss moduli for the swarm.
Environmental perturbations induce correlations in midge swarms
TLDR
It is shown that collective behaviour cannot be understood in isolation without considering its environmental context, and that new research is needed to disentangle the distinct roles of intrinsic dynamics and external stimuli.
Intrinsic stochasticity and the emergence of collective behaviours in insect swarms

TLDR
It is shown how intrinsic multiplicative noise allows for the nucleation of swarms away from prominent visual features known as swarm markers, and is shown that these newly identified states are analogous to interstellar clouds and extend a long-standing analogy between insect swarms and self-gravitating systems.
On the emergence of gravitational-like forces in insect swarms
  • A. Reynolds

TLDR
It is shown how resultant centrally attractive gravitational-like forces can emerge from the observed tendency of insects to continually switch between two distinct flight modes: one that consists of low-frequency manoeuvres and one that consisting of higher-frequency nearly harmonic oscillations conducted in synchrony with another insect.
Understanding the thermodynamic properties of insect swarms
TLDR
It is shown how the effective interactions can be attributed to the swarms’ internal structure, the external perturbations and to the presence of intrinsic noise, which is known to be crucial for the emergence of the macroscopic mechanical properties of insect swarms is also crucial for their thermodynamic properties as encapsulated by their equation of state.
Stochastic modelling of bird flocks: accounting for the cohesiveness of collective motion
TLDR
This paper argues that Okubo's stochastic model also encapsulates the cohesiveness mechanism at play in bird flocks, namely the fact that birds within a flock behave on average as if they are trapped in an elastic potential well, and shows how the model can be extended to account for intrinsic velocity correlations and differentiated social relationships.
On the origin of the tensile strength of insect swarms
TLDR
It is shown that swarms of flying insects have macroscopic mechanical properties similar to solids, including a finite Young's modulus and yield strength, and that the emergence of these solid-like properties can be attributed to centre-of-mass movements (heat).
Insect swarms can be bound together by repulsive forces

TLDR
It is shown how individuals reduce the potential for the loose of flight control by minimizing the influence of jerks to which they are subjected, and adds to the growing realization that insect swarms are analogous to self-gravitating systems.
Analysis of aligning active local searchers orbiting around their common home position.
TLDR
The effects of pairwise aligning interactions in an ensemble of central place foragers or of searchers that are connected to a common home and expressions for the critical interaction strength, the mean radial and orbital velocities of the searchers and their velocity variances are discussed.

Are midge swarms bound together by an effective velocity-dependent gravity?
TLDR
It is shown that the observed kinematics implies that individual attraction to the swarm centre increases linearly with distance from the Swarm centre, and that this attraction also increases with an individual's flight speed.
Emergent dynamics of laboratory insect swarms
TLDR
Three-dimensional, time-resolved measurements of the positions, velocities, and accelerations of individual insects in laboratory swarms of the midge Chironomus riparius show that the swarms display an effective large-scale potential that keeps individuals bound together, and characterize the shape of this potential.
Collective Behaviour without Collective Order in Wild Swarms of Midges
TLDR
It is found that correlation increases sharply with the swarm's density, indicating that the interaction between midges is based on a metric perception mechanism, suggesting that correlation, rather than order, is the true hallmark of collective behaviour in biological systems.
Velocity correlations in laboratory insect swarms
TLDR
Measurements of spatial velocity correlation functions in laboratory mating swarms of the non-biting midge Chironomus riparius suggest the potentially important role of environmental conditions on collective behavior, and suggest that general indicators of the collective nature of swarming are still needed.
Phase Coexistence in Insect Swarms.
TLDR
Inspired by thermodynamics, topological data analysis is applied to laboratory insect swarms and it is shown that the swarms consist of a core "condensed" phase surrounded by a dilute "vapor" phase, which maintain their distinct macroscopic properties even though individual insects pass freely between them.
Determining asymptotically large population sizes in insect swarms
TLDR
These findings support the feasibility of using swarms as a design template for multi-agent systems, because self-organized states are possible even with few agents, and provide a strong constraint on how rapidly swarm models must produce collective states.
On the tensile strength of insect swarms
TLDR
The results suggest that swarms surprisingly have macroscopic mechanical properties similar to solids, including a finite Young’s modulus and yield strength, and that they do not flow like viscous fluids.

TLDR
Analytical results provide insights into why the identified individual midge sensing characteristics and flight rule lead to cohesive swarm behavior.
Searching for effective forces in laboratory insect swarms
TLDR
The results suggest that some attractive interaction maintains cohesion of the swarms, but that this interaction is not as simple as an attraction to nearest neighbours.
Long-range acoustic interactions in insect swarms: an adaptive gravity model
TLDR
This work exploits the similarity in form between the decay of acoustic and gravitational sources to build a model for swarm behavior and shows that the ‘adaptive gravity’ model makes mean-field predictions that agree well with experimental observations of laboratory swarms.
