Madagascar is a normally sunny island off the east coast of Africa. Yet for the past three years, the skies above it have occasionally turned black—with locusts! Swarms of the hungry insects are eating their way through the country’s crops.
Humans have dealt with locust swarms since the beginning of recorded history. The insects’ presence can mean disaster for a community. Anywhere from 40 million to 80 million locusts gather in an area about the size of 10 city blocks. Each insect tries to eat its own weight in food every day! A swarm can lead to food shortages and famine.
