Lycorma delicatula, better known as Spotted Lanternfly (SLF for short) is an invasive insect that was discovered in southeastern Pennsylvania in 2014 and is currently spreading to nearby states via major travel and trade routes. Because SLFs feed on a wide range of fruit, ornamental and woody trees and some agricultural crops, it has the potential to greatly impact Connecticut’s plant nurseries, vineyards and orchards. Trees such as maple, oak, pine, poplar and willow are at risk. Early detection is vital for the protection of Connecticut businesses and agriculture.

Young SLFs are black with white spots and develop red patches as they grow. Adults are about one inch long with a two-inch wingspan. The wings are spotted, and the hindwings have conspicuous red patches.
