Scientists discover new species of grasshopper, dragonfly and fluorescent spider

A conservation group reported that wildlife experts discovered eight new species of dragonfly in Angola, along with three unknown grasshoppers, and 60 vibrant-colored butterflies and moths.

The Wilderness Project visited four major African rivers that feed off the water flowing through the plateau: the Congo River, Okavango River, Zambezi river, and Cuanza.

The new species include an armoured predatory cricket, a copper caterpillar species and its adult butterfly that was previously unknown, as well as a crowned spider fluoresces when exposed to ultraviolet light.

Experts have also discovered a 'new blood orange-hued ladybird orb web spider that mimics ladybirds to signal to predators with a bright color - usually a darker shade of red - indicating it is too bitter?or toxic.

Rob Taylor, expedition leader, said: "The armoured insects are cool...very fierce-looking." As a defensive mechanism, they are able to squirt liquid onto anyone who is trying to attack. Scientists around the globe are trying to record as many species as possible in order to cope with an ecological crisis which has threatened a million animal and plant species. Scientists estimate that there are 8,7 million species in the world. However, only 1.5 million have been identified by science.

More than 800 species of animals have gone extinct in the last 1500 years due to?human activity.

Taylor stated that wildlife on the Lisima Plateau is threatened by "tree felling,?deforestation, and...the artisanal diamond mining industry." He also said that slash-and burn agriculture, which destroys natural forests in order to plant, washes away nutrients, threatens the animals.
