Novel analyses of a 31-year dataset on invading ladybeetles shows that small differences in habitat preference across years allow for two similar invading species to coexist while native species decline. Invasive species lead to novel interactions Invasive species are one of the main threats to biodiversity in an increasingly interconnected world. As humans move organisms around, either purposefully or incidentally, new combinations of species have the opportunity to interact with one another. These novel interactions have the potential to affect an invader’s persistence in the
