Grasshoppers thrive in hot, dry conditions

Grasshoppers are often worse in hot, dry conditions. One big reason is because insects, as cold-blooded creatures, eat more and grow faster in hot weather. The other reason is that hot, dry weather limits fungal infection, one of the main threats to grasshopper eggs. In dry weather, a larger proportion of eggs hatch.
