Classify these animals into 2 groups- then classify the two groups into two more. i will give 76 points for best answer.

The two groups can be animals that have wings and don't have wings. 

The wing group: 
butterfly, the bird(can't read name), cockroach, ladybug

Can actually fly, cannot fly should be the other two groups

Everything can fly but the cockroach

The non-wing group:
mouse, snake, starfish, snail, alligator, fish, crab

The two other groups should be: can be in water for extended periods of time, cannot be in water.

Everything but the mouse can be in water.
