Youâve no doubt heard about the large brood of 17-year cicadas that will soon emerge in New York City and beyond. If you garden, youâve probably wondered what these gigantic insects might do to your plants.The good news is that adult cicadas (Magicicada species), though large and noisy, do not tend to do much damage.icada grubs do eat plant roots and are a common underground pest, but theyâre not too serious, and any harm that this brood has done was done in previous years. The only damage adult cicadas are likely to cause plants, even during a heavy emergence, is from ovipositing.
