Thousands of grasshopper specimens from mountains in Colorado show trends in how the insects changed in size over 65 years. With earlier emergence of spring greenery and earlier summer drought, grasshopper species that emerged early in the year grew larger, while grasshopper species that emerge later in the year grew smaller in size. The study, led by UW biologist Lauren Buckley, shows that changes in insect size can be predicted based on lifecycles and environmental conditions.
