MADRID: Millions of moths have engulfed Madrid in a population explosion blamed on spring rains, a sudden blast of summer heat and winds that have wafted them in as unwelcome guests to the Spanish capital. Across the city, people are swapping tales of night-time battles to swat moths lured by the light into their bedrooms, a whole new genre of jokes has been born and the phenomenon has become a trending Twitter topic.
No-one is sure of precisely where they came from. Roger Vila, researcher at the butterfly diversity and evolution laboratory in the northeastern city of Barcelona, identified three types of moth from photographic evidence: the Gamma, Noctua and Catocala.
