A Kenyan court on Wednesday fined four men $7,700 each for trying to traffic thousands of ants valuable to the country's ecosystem, in cases experts say signal a shift in biopiracy from trophies like elephant ivory to lesser-known species.

A Kenyan court has sentenced four men to one year in prison or pay a fine of $7,700 (£5,800) for trying to smuggle thousands of live queen ants out of the country. The four suspects – two Belgians, a Vietnamese and a Kenyan – were arrested last month with live ants suspected to have been destined for collectors in Europe and Asia.

Authorities said the ants were destined for European and Asian markets in an emerging trend of trafficking lesser-known wildlife species.
