Monarch butterfly numbers decline again in Mexican wintering grounds
.
BBC news
Speaking at a news conference in Mexico City, officials said nine colonies of monarch butterflies had been recorded in Mexico in the 2017/2018 winter months, down from 13 last year.
Mr del Mazo said that "extreme meteorological events" could be a leading cause in the decline of the numbers of Monarch butterflies overwintering in Mexico.
World Wildlife Fund's Mexico Director Jorge Rickards said a particularly busy hurricane season across the insects' migration route, which stretches almost 5,000km (3,100 miles) from Canada to Mexico, could be a factor.
"These climate phenomena without a doubt have an impact on the migration," he said.
Monarchs are one of the few insects to migrate such a vast distance and scientists recently found that they use a kind of internal solar compass to guide them.
