In 1845, Adam White classified two new species under the genus '' Aphaena'', ''Aphaena imperialis'' and ''Aphaena delicatula''. 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 lanternflies. Between 1846 and 1863, the species were reclassified by both John O. Westwood and Francis Walker. In 1863, the genus ''Lycorma'' was formally established by

Accidental introduction

In 2006, ''L. delicatula'' was discovered to have invasively spread to South Korea. In 2009, ''L. delicatula'' was discovered in Japan, and in 2014, the species was discovered in the United States. ''L. delicatula'' may have previously entered Japan sporadically since the 1930s, but only achieved a stable population in the early 2000s. It is believed that ''L. delicatula'' entered these countries via egg masses that were laid on exported goods. Currently, these countries have implemented
