The Mediterranean fruit fly ("Ceratitis capitata") exhibits left-biased population-level lateralisation of aggressive displays (boxing with forelegs and wing strikes) with no sex-differences. In ants, "Temnothorax albipennis" (rock ant) scouts show behavioural lateralization when exploring unknown nest sites, showing a population-level bias to prefer left turns. One possible reason for this is that its environment is partly maze-like and consistently turning in one direction is a good way to search and exit mazes without getting lost. This turning bias is correlated with slight asymmetries in the ants' compound eyes (differential ommatidia count).
