Distribution and year: Okavango Delta 2018/2019 ( Malatji et al. 2019).

Native range: Europe and Asia ( Larson 2018).

Extent of invasion: The species has a wide invasion expansion range in North America ( Larson 2018) and New Zealand (Winterbourn 2023), and has recently been discovered in the Okavango Delta, Botswana, and KwaZulu-Natal, South Africa ( Malatji et al. 2019).
