Ecological Threat With Massylaea vermiculata having a long lifespan from 2 to 5 years an established population can continually grow. The long lifespan could make this species grow from a minor concern to a major concern for native gastropod species, garden plants and agricultural crops alike. Vineyards are very threatened with Massylaea vermiculata being observed on grape plants in their native range. Management This species is considered to represent a potentially serious threat as a pest, an invasive species which could negatively affect agriculture, natural ecosystems, human health or commerce.
