Spotted Lanternflies are a hot topic lately, and we love seeing the public take interest in invasive species! We are ALL citizen conservationists (yes, you too!), and we ALL are responsible for the ecosystems we live in.
This colorful leaf-jumper drinks sap from its host plants, which can damage native trees and woody flora that haven't co-evolved to handle the pressure from SLFs. They threaten crops such as cultivated grape vines, with some farmers reporting a 90% decrease in crop production due to SLF infestations. 🤯
Trees can suffer from leaf wilting, reduced crowns, and eventual death as a result of prolonged infestations. The sappy residue SLFs leave behind can increase the possibility of black mold growth, as well (but more research is needed here to understand the full implications!). Their eggs are well-camouflaged, making it hard to find and remove them.
Some stages of SLFs show a strong preference for the invasive Tree-of-Heaven (Ailanthus altissima). There is some evidence that removing the ToH can help combat Spotted Lanternflies, too!
Plus, researchers are beginning to observe several NATIVE species who are learning to eat SLFs! Several species of bats, spiders, the Carolina Chickadee, and the Red-bellied Woodpecker are slowly learning to treat the SLF as a food source. This could help keep their numbers from exploding too far out of control, but certainly isn't a cure for the problem.
Removal of SLFs is still encouraged, but not all methods are equal! For example, do NOT USE GLUE TRAPS! Sticky traps are indiscriminate and inhumane, even when they have a "wildlife guard" over them.
