New Zealand imports dung beetles to deal with livestock dung

New Zealand has approved releasing dung beetles to tackle the country's livestock dung problems. The dung beetles will come from Australia, which introduced beetles from Africa and Europe in the 1960s. Beetles lay eggs in dung, and the larvae eat it. This prevents emissions from rotting dung, and parasitic worms and flies using it to breed.
