Grasshoppers are some of the sneakiest little insects I've encountered. Now you see them, now you don't; it really takes a patient approach to get pictures of them. They will all of a sudden appear, and if I don't have my lens pointed in the right direction, they will hop away the moment I take my eye off of them. Fortunately, on a hot summer day, they seem to be out in abundance, so there are many more attempts to be made.
