When resting, the crimson hind wings are partially visible through the semi-translucent forewings, giving the lanternfly a red cast. White's original account identified L. delicatula as having a minimum of 20 black spots, with 6 spots located on the anterior margin of the forewings. Adult lanternflies have a black head and gray-brown forewings adorned with black spots. Spotted lanternfly in New York, where it is an invasive speciesĪdult L. delicatula measure about 25 millimetres (1 in) long and 12 millimetres ( 1⁄ 2 in) wide. In 2019, the genome of L. delicatula was fully sequenced, with Aphaena amabilis, and Pyrops candelaria both being classified as close relatives. L. delicatula is also referred to as the spot clothing wax cicada ("chu-ki" or "banyi-la-chan" in Chinese) and the Chinese blistering cicada ("ggot-mae-mi" in Korean). The name Lycorma delicatula derives from lyc/lyco, meaning "lamp" and delicatula, meaning "luxurious". Taxonomic classification places two other species ( L. imperialis and L. meliae) as closely related to the spotted lanternfly. In 1863, the species was reclassified by Carl Stål as Lycorma delicatula delicatula, with two additional subspecies described: Lycorma delicatula jole and Lycorma delicatula operosa. White described the species as similar to Aphaena variegata, another planthopper species native to Asia, and referenced prior descriptions by George Tradescant Lay in his initial classification of the spotted lanternfly.
L. delicatula was originally described by Adam White in 1845 as Aphaena delicatula, and the first scientific collections were made outside of Nanking, China.
Species within this genus are found in Asia. Lycorma delicatula is a species in the genus Lycorma, in the planthopper family Fulgoridae, subfamily Aphaeninae. Ongoing pest control efforts have sought to limit population growth, due to the threat L. delicatula poses to global agricultural industries. L. delicatula's egg masses have been found to be the primary vector of spread, with Ailanthus altissima populations seen as a risk factor for further infestation globally. In September 2014, L. delicatula was first recorded in the United States, and as of 2022, it is an invasive species in much of Northeastern United States and is rapidly spreading south and west. The species was accidentally introduced into South Korea in 2006 and Japan in 2009, and has since been considered a pest. In temperate climates, these egg masses overwinter. Spotted Lanternflies lay egg masses containing 30-50 eggs, often covered with a grayish mud-like coating. The piercing wounds caused by their mouthparts and the honeydew waste they excrete have been found to be significantly detrimental to the health of host plants. Adults do not display any specialized feeding associations with herbaceous plants but have been known to cause extensive damage to crops and ornamental plants. Adult spotted lanternflies display a black head, grey wings, and red hind wings. Early life instars display a large host range that narrows with maturation. Early life stages ( instars) of the spotted lanternfly are characterized by spotted black and white nymphs that develop a red pigmentation and wings as they mature. The spotted lanternfly's life cycle is often centered on its preferred host Ailanthus altissima but L. delicatula can associate with more than 173 plants. In its native habitat, L. delicatula populations are kept in check by parasitic wasps. Its preferred host is tree of heaven ( Ailanthus altissima), but it infests economically significant plants including soybean, grapes, stone fruits, and Malus spp. It has spread invasively to Japan, South Korea, and the United States. The spotted lanternfly ( Lycorma delicatula) is a planthopper indigenous to parts of China and Vietnam.
