The spotted lantern flies a herbivorous insect that is native to Asia and feeds on over 70 species of plants. The feeding behavior of the spotted lantern, fly damages plants, and the nymph in adult lantern, flies, secrete, sticky residue that attribute the damage to native plant species by promoting mold, growth, the spotted lens or fly reproduces, one serving its lifetime by laying between 50 and 30 eggs and eggs hatch. After a short amount of time the range of the spotted lantern flies increasing because the insects are transported to new environments by the movement of animals and people it is now found in many parts of the United States. which of the following best describes a spotted lantern fly in the United States?
