Landing Bee - Stingless Bees Play An Essential Role In The Fertilization Of Plant Species, And Are The Main Pollinators Of Many Plants In The Brazil. The Majority Of These Plants Are Bisexual, Requiring An External Agent For Carrying Pollen From One Flower To Another. According To Johnson & Hubbell (1974), Meliponinae Make Up The Greatest Share Of Insect Biomass Feeding On Pollen And Nectar. The Massive Presence Of These Insects In The Flowers Makes Up Such An Ecological Complex And Such An Interaction, That Without Plants, Bees Would Disappear Within Two Months. Likewise, Without Bees, The Many Flowering Plant Species Would Disappear Within One Or Two Generations Photo
