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, though to what degree it aids their spread needs further study.
Spider mites may adapt to uncertain environments by successfully inbreeding and by adjusting reproductive resources, a new study shows. The findings may help entomologists better understand and manage invasions by other haplodiploid arthropods.

The big-headed ant (Pheidole megacephala) is considered one of the world’s worst invasive ant species. As the name implies, its colonies include soldier ants with disproportionately large heads. Their giant, […]
