Download the ladybug template and print it out. If you're using the color in version, have the kids color in the pieces before cutting them out.
Begin by gluing the eyes near the bottom of the head, just above the mouth.
Flip the head over, so the mouth is at the top and glue it to the top and middle of the ladybug's body.
Take a piece of tape on the end of one side of the ladybug's body and tape it to the toilet roll. Place another piece of tape on the opposite side, wrap it around the cardboard tube, and tape it in place.
Finish up by gluing the ladybug's wings in the middle of the ladybug's body, slightly overlapping the eyes.
