Slice the cherry tomatoes in half vertically. Lay the halves flat side down, then cut a small slit to create the wings of the ladybug. Gently wiggle the knife back and forward to open the slit to make the wings more pronounced.
Cut each olive in half horizontally, then cut each half in half again horizontally so you have four pieces. These will create the head of the ladybug.
Lay the mozzarella slices on a platter. Top each piece of mozzarella with a basil leaf. Place a cherry tomato half on the basil leaf to create the body of the ladybug. Add one of the olive pieces at the top of the sliced cherry tomato.
Using a toothpick, dot the balsamic reduction onto the cherry tomatoes to create the ladybug spots.
