Behavioral lateralization is widespread across the animals, being found in numerous vertebrate
species as well as in species from across many invertebrate phyla. Numerous recent studies
have focused on lateralization in the insects, exploring the behaviors themselves as well as
their neural basis and the possible selective pressures that led to their evolution. Lateralization
in the insects can occur in any sensory modality and may be generated by peripheral or central
neural asymmetries. The lateralization of particular insect behaviors can show either populationlevel
or individual-level lateralization but which of these types of lateralization is present is
strongly influenced by their social environment. Different behaviors fromthe same species show
population-level or individual-level lateralization depending on whether these behaviors are
used in social interactions or not. This has broad implications for our understanding of how lateralization
and handedness evolves not just in insects but also in vertebrates.
