So they can run away from predators
no
they jump so hog high because they need to be able to catch their prey

Lots of bugs can jump extremely high for their size. One notable example is the grasshopper, but there are many others.
This might not be too helpful, but grasshoppers can jump about twenty times their own size.
A grasshopper can leap to about 20 inches, which is 20 times the length of its body. Some species are said to be able to jump even farther.

Most likely yes. A 1 inch grasshopper can jump 20 inches, or a little under 2 ft http://animals.howstuffworks.com/insects/grasshopper-info.htm
The grasshopper wouldn't be able to jump!
Grasshoppers can jump up to 20 times the length of their body. Grasshoppers can also fly. While flying they can reach speeds of 8 miles per hour.
Being bigger, a kangaroo jumps further than a grasshopper. However, in proportion to the size of the creature, a grasshopper jumps further.
If a man could jump like a grasshopper, he could potentially leap several times his height. Grasshoppers can jump up to 20 times their body length, which translates to impressive vertical heights. For an average man, this could mean jumping anywhere from 10 to 15 feet high, depending on his size and weight. However, this is purely hypothetical, as human physiology differs significantly from that of grasshoppers.
