Major 190-mile road will strip national park and home to thousands of indigenous people of its protected status, making it vulnerable to deforestation

Bolivia has given the go ahead to a controversial highway which would cut through an Amazon biodiversity hotspot almost the size of Jamaica and home to 14,000 mostly indigenous people.

President Evo Morales enacted the new law opening the way for the 190-mile (300km) road through the Isiboro Sécure Indigenous Territory and National Park, known as Tipnis, its Spanish acronym.

The mid-thorax, hind legs and head were all glittering turquoise, while the abdomen and front thorax were shining burgundy. The unmistakable colours distinguish a small group that are known as jewel or ruby-tailed wasps (in German they are called Goldwespen, gold wasps), of which there are about 30 species in Britain.
