It was first discovered in North America in southeastern Pennsylvania in 2014. Additional infestations, or individual SLF or egg masses, have since been documented in several other states.
SLF feed on a wide variety of woody and herbaceous plants, causing wilting and dieback and stress that can make host plants more susceptible to damage by other biotic or abiotic factors. Favored hosts include the non-native invasive tree-of-heaven, grapes, and hops. In addition to feeding damage, SLF nymphs and adults produce copious amounts of sticky, sugary liquid known as “honeydew” which can be attractive to ants, flies, and wasps. The honeydew is also colonized by a fungus called “sooty mold” which can ruin grape and hops harvests, decrease photosynthesis, and is generally unsightly. SLF nymphs and adults may also congregate in swarms in yards and farms, making them a nuisance pest. Egg masses laid by females are light gray and covered by a mud-like substance and can be deposited on nearly any relatively flat surface such as tree trunks, buildings, fences, rocks, vehicles, or train cars.
Management of SLF is focused on preventing their spread on vehicles or other objects through quarantines, trapping of nymphs, removal of host plants, and chemical control.
