Wasps, cockroaches and crickets are pollinators too
(PHYSorg.com Biology)

Wasps, cockroaches and crickets are widely disliked, but for a certain species of plant on the Japanese island of Yakushima they play a vital role. While studying the non-photosynthetic Mitrastemon yamamotoi plant, Associate Professor Kenji Suetsugu revealed that these insects were responsible for its pollination. Suetsugu is a member of the Kobe University Graduate School of Science, and these findings were published in the January 2019 edition of Plant Biology.
