Crickets, katydids, and grasshoppers are a very diverse group of bugs that are generally safe to eat, as long as you avoid the more colorful members of these families; red, orange, yellow, and blue are usually warning colors. With the more drab specimens, the heads and small legs should be removed, and the bugs should always be cooked thoroughly, as bugs with crunchy shells (exoskeletons) are more prone to harbor parasites. Hunt for them in the early morning when they are less active due to the colder temperatures. This group yields approximately 4 to 5 calories per gram. Their flavor ranges from bland to fatty.
