Answer 2

Answer:

When a worker discovers a good source of nectar or pollen (note the pollen spores dusting this bee's back), she will return to the hive to perform a waggle dance to let her nest mates know where it lies. A bee performs the waggle dance when she wants to inform other bees of a nectar source she has found.
