DID YOU KNOW?  BLM Idaho is using bugs to control invasive plant species!  These specially-adapted bugs are known as biological control agents.  Some of the invasive plants in Idaho and their corresponding “bombastic bugs” include:

  • Dalmation Toadflax – Toadflax Stem Weevil
  • Rush Skeletonweed – Root Moth ‘Bradyrrhoa Gilveolella’
  • Leafy Spurge – Leafy Spurge Red-Headed Stem Borers

2nd FUN FACT:  “The toadflax stem weevil has reduced Idaho Dalmatian Toadflax populations by 97%. The adult female beetle lays eggs in the stems where larvae develop, pupate and burrow out of the stem each spring, decimating the plant.”  – Joey Milan, BLM Idaho Entomologist (via Facebook).

Check out the BLM Idaho’s Facebook page to find out why Dalmation Toadflax needs to be eliminated from public lands, here:
