Spotted Lanternflies Spotted at Tinker! STOMP ON SIGHT!
Native to parts of China and found in adjacent countries in Asia (south Korea and Japan) where they were most likely introduced, they have spread dangerously and unregulated to our local states.
Why are they a problem? And why murder them?
They are plant hoppers and like all plant hoppers they suck the sap from plants, piercing the tissue of foliage and stems, and producing honeydew (sugary waste fluid.) The lantern flies do so both in their early and adult life stages, but the older- the more dangerous. The lantern fly’s produced excretion promotes the growth of sooty mold. It covers the plant below where they’re feeding, which is not pretty, but it’s not just an aesthetic issue. This mold damages the plant’s ability to photosynthesize and will make affected crops inedible. In its native habit it is regulated by parasitic wasps here, however, there is no such balance.
The Spotted Lantern Fly’s preferred host plant is the invasive Tree of Heaven, but it’s known to also feed off more than 70 other plants, including other trees, ornamentals, and crops, both native and economic, including soybean, grapes, stone fruits, domesticated apple and willow trees. Maple trees, which grow prolifically here at Tinker Nature Park, are a special target, because of their sweet, sweet sap. Impairing its growth by almost 50% and leading to long term damage in the tree’s stored energy, that can last seasons.
Its effects lead to a decrease in its host plant’s health as well as possibly killing them, posing a major risk to plants and crops, the balance of the ecosystem, and your comfort in nature. Pennsylvania State University estimated statewide costs to be $99 million in agricultural losses, and $236 million in the forest industry, ranging to $554 million if they were to continue to spread to all of Pennsylvania.
With no current specified way to treat this invasive insect here in NY, the best we can do now is stomp them on sight, or with other deadly methods (like slapping).
