spotted lanternfly nymphs
The spotted lanternfly (Lycorma delicatula) passes through four nymphal instars. The first three instars are black with white spots (such as the one pictured at right). The fourth instar (left) develops red patterning on the head, thorax, and abdomen, while still retaining some white spotting.
