Summary
Globally, dung beetles (Scarabaeidae: Scarabaeinae) are linked to many critical ecosystem processes involving the consumption and breakdown of mammal dung. Due to New Zealand's unique evolutionary history, resulting from its geographic isolation from Gondwana, endemic dung-dwelling fauna evolved in the absence of large mammals. Europeans introduced livestock to the islands in the late 18th and 19th centuries, resulting in a buildup of undecomposed feces and unrecycled nutrients due to the absence of dung beetles. To mitigate this situation, in 2011, the New Zealand Environmental Protection Agency approved the release of 11 species of exotic beetles with the expectation that these insects would fulfill a critically missing link in converting aboveground manure biomass into higher quality so
