A larva is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle.
Eörs Szathmáry is a Hungarian theoretical evolutionary biologist at the now-defunct Collegium Budapest Institute for Advanced Study and at the Department of Plant Taxonomy and Ecology of Eötvös Loránd University, Budapest. He is the co-author with John Maynard Smith of The Major Transitions in Evolution, a seminal work which continues to contribute to ongoing issues in evolutionary biology. He is a member of the Batthyány Society of Professors.
Thomas Eisner was a German-American entomologist and ecologist, known as the "father of chemical ecology." He was a Jacob Gould Schurman Professor of Chemical Ecology at Cornell University, and Director of the Cornell Institute for Research in Chemical Ecology (CIRCE). He was a world authority on animal behavior, ecology, and evolution, and, together with his Cornell colleague Jerrold Meinwald, was one of the pioneers of chemical ecology, the discipline dealing with the chemical interactions of organisms. He was author or co-author of some 400 scientific articles and seven books.
The Polistinae is a subfamily of eusocial wasps belonging to the family Vespidae. They are closely related to the wasps and true hornets of the subfamily Vespinae, containing four tribes. With about 1,100 species total, it is the second-most diverse subfamily within the Vespidae, and while most species are tropical or subtropical, they include some of the most frequently encountered large wasps in temperate regions.

He is a former member of the Scientific Advisory Council to the Prime Minister of India and the Head of the Western Ghats Ecology Expert Panel (WGEEP) of 2010, popularly known as the Gadgil Commission.
Sociality is the degree to which individuals in an animal population tend to associate in social groups (gregariousness) and form cooperative societies.
The gyne is the primary reproductive female caste of social insects. Gynes are those destined to become queens, whereas female workers are typically barren and cannot become queens. Having a queen is what makes a "queenright" hive, nest, or colony of eusocial insects. A colony with multiple queens is said to be a polygyne form, whereas one with only one is a monogyne form.
Spatial organization can be observed when components of an abiotic or biological group are arranged non-randomly in space. Abiotic patterns, such as the ripple formations in sand dunes or the oscillating wave patterns of the Belousov–Zhabotinsky reaction emerge after thousands of particles interact millions of times. On the other hand, individuals in biological groups may be arranged non-randomly due to selfish behavior, dominance interactions, or cooperative behavior. W. D. Hamilton (1971) proposed that in a non-related "herd" of animals, the spatial organization is likely a result of the selfish interests of individuals trying to acquire food or avoid predation. On the other hand, spatial arrangements have also been observed among highly related members of eusocial groups, suggesting that the arrangement of individuals may provide advantages for the group.
Task allocation and partitioning is the way that tasks are chosen, assigned, subdivided, and coordinated within a colony of social insects. Task allocation and partitioning gives rise to the division of labor often observed in social insect colonies, whereby individuals specialize on different tasks within the colony. Communication is closely related to the ability to allocate tasks among individuals within a group. This entry focuses exclusively on social insects. For information on human task allocation and partitioning, see division of labour, task analysis, and workflow.
Eusociality, the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care, overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes referred to as 'castes'. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste. Eusocial colonies can be viewed as superorganisms.
Ropalidia is a large genus of eusocial paper wasps (Polistinae) in the tribe Ropalidiini distributed throughout the Afrotropical, Indomalayan and Australasian biogeographical regions. The genus Ropalidia is unique because it contains both independent and swarm-founding species. Ropalidia romandi is one of the swarm founding species, meaning that new nests are founded by a large group of workers with a smaller number of inseminated females, while Ropalidia revolutionalis is independent-founding, meaning that each nest is founded by a single foundress.
Ropalidia marginata is an Old World species of paper wasp. It is primitively eusocial, not showing the same bias in brood care seen in other social insects with greater asymmetry in relatedness. The species employs a variety of colony founding strategies, sometimes with single founders and sometimes in groups of variable number. The queen does not use physical dominance to control workers; there is evidence of pheromones being used to suppress other female workers from overtaking queenship.
Mary Jane West-Eberhard is an American theoretical biologist noted for arguing that phenotypic and developmental plasticity played a key role in shaping animal evolution and speciation. She is also an entomologist notable for her work on the behavior and evolution of social wasps.
Somdatta Sinha is an Indian researcher and professor of biology, who is one of the earliest to start working in the area of theoretical biology in India. Her expertise is in the interdisciplinary fields of mathematical & computational biology, nonlinear dynamics and complex systems with a view to understand the logic and design of biological processes. She studies spatio-temporal organization in biological systems – from biological sequences to spread of disease in populations – using mathematical and computational methods. She has played a central role in the development of mathematical and computational biology in her country through research, organization of scientific meetings, training programs, conferences, and teaching interdisciplinary courses at the undergraduate and postgraduate levels. Her research encompasses patterns, interactions, and dynamics of biological systems using mathematical and physical methods to understand complex multi-scale biological systems. Sinha's research contributions focus on modelling a variety of biological systems, such as, circadian rhythms, pattern formation, biochemical pathways, synthetic biology, single and meta-population ecological models, epidemiology, and controlling spatiotemporal dynamics. She has also carried out computational analysis of genomes for classification of organisms using Chaos Game Representation (CGR) and Multi-fractal analysis, protein structure-function analysis using graph theory, and network analysis of large biochemical pathways. Her publications have made important contributions in the respective fields and are highly cited. Her seminal contribution to the development of the interdisciplinary field of Mathematical and Computational Biology in India was acknowledged by the Department of Biotechnology, Govt of India with the National Senior Woman Bioscientist Award in 2013 and the J C Bose National Fellowship from the Department of Science and Technology, Govt. of India. She is a fellow of the Indian National Science Academy, Indian Academy of Sciences and National Academy of Sciences. She was elected Fellow of the Wissenschaftskolleg zu Berlin for 2000-2001 and International Visiting Research Scholar at the Peter Wall Institute for Advanced Studies at the University of British Columbia, Vancouver, Canada in 2018. She has traveled widely across the globe and given many invited talks in universities and conferences.
Kladothrips is a genus of Australian gall thrips. It is notable for including some of the few organisms outside of Hymenoptera that exhibit eusociality.
Ropalidia fasciata, a common paper wasp, is a wide-ranging species that is distributed from India to the Lesser Sunda Islands, Palawan, and Ryukyu Islands, occupying the northern edge of Ropalidia's larger distribution. These primitively eusocial wasps are unique in that they do not exhibit the strict matrifilial, single-queen social structure found in many species of social insects. Instead, colonies are founded based on associations between several females, or 'foundresses'.
