Introduction

Immature spotted lanternfly, Lycorma delicatula (White), are black with white spots when young (Fig. 1). They turn red and black with white spots when older (Fig. 2). A few other insects in Virginia have similar color patterns and/or distinctive markings, but a close look will show that immature spotted lanternflies are easily recognizable from these other possible look-alike insects (Figs. 3-9). Sizes are not to scale.
