With several hundred species, the stingless bees (Meliponini) are the largest group of highly eusocial bees. As their name suggests, a distinctive feature of the stingless bees is the evolutionary loss of the sting. However, stingless bees are not defenceless and show many adaptations to defence against parasites and predators.The aim of this project is to study the alternative strategies that Tetragonisca angustula uses as nest defense.
