spotted lanternflies on tree

Approximately two dozen spotted lanternflies amass in a sunny spot on the side of a tree in a shady forest.

Producing offspring from multiple fathers can add much-needed genetic diversity to populations of invasive insects, which often arise from a small number of individuals. New research confirms such multiple paternity occurs in spotted lanternflies (Lycorma delicatula), though to what degree it aids their spread needs further study. (Photo by Stefani L. Cannon)
