Why do grasshoppers only come out in summer?

Grasshoppers are warm-weather insects that thrive in temperatures conducive to their growth and reproduction. They are ectothermic, meaning their activity levels and metabolic rates are heavily influenced by external temperatures. During the summer, the warmth and abundance of vegetation provide ideal conditions for feeding and mating, while cooler temperatures in spring and fall can limit their activity. Additionally, many species have life cycles that include a dormant egg stage, which hatches when conditions are favorable in summer.
