Default Why is grasshopper more adapted to dry land than crayfish?



Hi,
Anyone know why is grasshopper more adapted to dry land than crayfish? I have looked through books and searched a lot, but I am still unable to reach an answer :/ I would assume it is because of the wing and the legs? But I am not quite sure... Please help, thanks in advance.

Most importantly, the crayfish still has gills, his hard exoskeleton keeps him from drying out for days at a time, but if you keep him out of water or humidity, he will dry up and suffocate. The grasshopper uses a spiracle-tracheal respiratory system that is primitive in design, but effective for him, and completely adapted for living on land.
