Two new invasive flatworm species discovered in Sweden

Summary
Two new species of invasive land flatworms have been discovered in Sweden, adding to the previously found Obama nungara (leaf flatworm) first detected in Malmö in fall 2024. The flatworms are spreading primarily through imported plants from nurseries, and have shown ability to survive Swedish winters. A possible additional spread mechanism is that they use slime to "hitchhike" on other animals.

· 4 pulledHösten 2024 gjordes det första fyndet av den invasiva lövplattmasken (Obama nungara) i Malmö.
Arten har sedan dess spridit sig i Sverige, framför allt via plantskolor som importerat plantor från andra länder där plattmasken redan är etablerad.
Den har också visat sig överleva en svensk vinter.
Förutom trädgårdsbranschen är en möjlig spridningsväg att de använder slem för att 'lifta' på andra djur.
