Centaurea cyanus
Beetle banks are typically made up from plants such as sunflowers, "Vicia faba", "Centaurea cyanus", coriander, borage, "Muhlenbergia", "Stipa", and buckwheats ("Eriogonum spp."). Beetle banks are used to reduce or replace the use of insecticides, and can also serve as habitat for birds and beneficial rodents. For example, insects such as "Chrysoperla carnea" and the Ichneumon fly can prey on pests. The concept was developed by the Game &amp; Wildlife Conservation Trust in collaboration with the University of Southampton.
