Wasps compete for the 'best trade deals': Study
A UK-based study has found wasps follow the 'supply and demand' theory and compete for the best trade deals with trading partners. 'Helper wasps' raise the offsprings of dominant breeders in exchange for staying in the nest. When alternative nesting options are available, dominant wasps compete to give the 'best deal' to 'helper wasps' and allow them to work less.
