Some wasps do pollinate and are very important such as the Masarine family of wasps that are also known as pollen wasps and are also herbivores who will only feed on flower nectar and pollen. Some of these herbivore wasps pollinate fig trees only. Pollen wasps can be found in most parts of the world while they prefer warm and semi arid to tropical conditions. Pollen wasps feed on a range of pollens from many different flowers, pollinating as a result. In an evolved co-existence, fig trees are pollinated only by wasps. Every individual species of fig tree has its own species of wasps that pollinate them. The female wasp does this as a result of laying her eggs inside the fig. While the female wasps burrows into the fig, she brings with her pollen she has on her from her home fig flower. With her eggs laid in the fig, she remains in the fig where she dies. her eggs hatch into larvae who spend their larvae stages inside the fig. Once they mature into adults, males and females leave the fig. They search for mates with the males then dieing once mated. The females then find their own fig in witch they will burrow and lay their own eggs while pollinating the new fig with pollen from the fig they were born.
