Invasive Animals

Citrophilus mealybug

Pseudococcus calceolariae

Citrophilus mealybug feeds on the phloem of deciduous and evergreen plants in warm, temperate climates. They are often hidden from view, and cannot be seen without cutting open the fruit.

Common boa

Boa constrictor

The boa constrictor is a large snake that can reach lengths of anywhere from 0.91–3.96m. They generally live on their own, and do not interact with any other snakes unless they want to mate. Their bite can be painful, especially from large snakes, but is rarely dangerous to humans. They are popular within the exotic pet trade, and are both captured in the wild and bred in captivity.

Common carp

Cyprinus carpio

The Common Carp is a large freshwater fish, growing up to 1m in length and 24 kg in weight. Both colour and scales are variable in this species. It can be found in much of South Africa, and has had a significantly negative impact on the environment. Competition with other organisms for the same food sources has resulted in biodiversity loss. 

Common Myna

Acridotheres tristis

A medium-sized chocolate-brown bird, with a yellow beak, eye patch, feet and legs. The head, throat and tail are black, with the tail having white tips and white undertail feathers. The large white patches in the wings are noticeably visible when the bird is in flight. Native to India, central and southern Asia. These birds compete for the same resources as indigenous species. 

Common peacock

Pavo cristatus

The common peacock male is large in size, with head plumes, blue body and massive “eyed” tail, while the female has a whitish face, green neck, mottled upper breast and white lower breast and belly. They come from Asia (Pakistan, India, and Sri Lanka), and naturalised populations are distributed in some parts of South Africa (mainly in the Western and Eastern Cape Provinces).
