I love grasshoppers. I learned in school that they've been around for about 250 million years?
Oh really! Their long legs freak me out! 
Their legs are kind of gross. I remember reading that grasshoppers need them to escape from predators.
I could understand that! They also have wings to escape from predators. I wonder what their predators are other than birds.
Maybe frogs? They also have freakish legs. I ate frog legs once - I wonder what grasshopper legs taste like?
Grass? 
If grasshopper legs tasted like grass, I could handle it. If they tasted like frog legs, no thanks. Filled with vitamins, but gross.
What did frog legs taste like? Can you compare them to some other type of food?
Frog legs
Frog legs are one of the better-known delicacies of French and Chinese cuisine. The legs of edible frogs are also consumed in other parts of the world, including Vietnam, Thailand, Indonesia, Northern Italy, the Alentejo region of Portugal, Spain, Albania, Slovenia, Romania, the northwest Greece and the Southern regions of the United States. As of 2014, the world's largest exporter of edible frogs is Indonesia. In Brazil, Mexico and the Caribbean, many frogs are still caught wild.
Grasshopper
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among what is probably the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. 
Grasshoppers are typically ground-dwelling insects with powerful hind legs which allow them to escape from threats by leaping vigorously. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a nymph or "hopper" which undergoes five moults, becoming more similar to the adult insect
