Ash trees, a common native tree species in this area, are being eaten by insects known as emerald ash borers. The insect was first identified in New York City in October 2017. And for the first time ever, the New York City Department of Parks and Recreation is releasing the wasps as a form of biocontrol — which is the reduction of pests through the use of natural enemies — against the invasive insects.
