the insects that can jump far are lion, frog, cheetah, rabbit.
Depending how long the frog takes to jump the 3ft and slide back 2ft between jumps, it will take it 17 times this duration (the frog will escape on the 18th jump and I assume the jumps take no time relative to the sliding back bit), which will then possibly be needed to be converted into hours.
