London’s Covent Garden has come up with a solution to a costly moth problem. “In a plot that could have come from an opera, males attempt to mate with the false females, but do not succeed. Until the new pheromone traps were pioneered by Exosect, a company with close links to Southampton University, moths were costing the Royal Opera House tens of thousands of pounds a year. The worst affected are ballet dancers’ costumes, which get engrained with sweat, clothes moths’ favourite taste.”
