Brood X, that is

Until the arrival of European settlers, most of the area the cicadas inhabit was forest — on the face of it, a good habitat for the insects. But Dr Clay's early research suggests that "suburban savannahs" (leafy avenues, lawns with the odd sapling growing in them, and golf courses) are actually better for the insects than the forests which preceded suburbanisation. Suburban trees tend to be younger and healthier. They also have to compete less fiercely for resources than trees in dense forests. And younger trees probably have tastier roots as well. The ancient forests of pre-Columbian America would not have provided such sumptuous dining.
