New York is once again turning the spotlight on the spotted lanternfly, an invasive insect that is advancing in urban and agricultural areas. Specialists and public agencies warn that its presence could increase due to the climate, its reproduction, and the spread of the tree of heaven. The insect, identified as Lycorma delicatula, arrived from Asia and has established itself in various points of the northeastern United States. According to New York University, it was officially detected in the state in 2020 and has since expanded its presence in several counties. Despite its name, it is not a fly but an insect that feeds on the sap of plants and trees. To do so, it drills into stems and trunks, which weakens the vegetation and leaves a sugary secretion that favors the appearance of fungi. Experts warn that it can feed on dozens of plant species. This flexibility explains part of its expansion in parks, sidewalks, yards, routes, and productive areas.
