This photo of the spotted lanternfly (Lycorma delicatula) in various life stages demonstrates its relative size next to a quarter. The first life stage—not pictured here—is an egg mass. Before becoming adults, the pest develops through the 1st, 2nd, 3rd, and 4th instar stages (shown). Starting in the fall, this invasive pest seeks out outdoor surfaces and lays mud-like egg masses on tree bark, outdoor gear (such as lawnmowers, bikes, and grills), methods of transport, and more.
