Combine chicken, carrots, celery and dressing in small mixing bowl; set aside. Slice each zucchini in half lengthwise to create 4 pieces. Using a melon baller, scoop out 5 semi-circles from the center of each zucchini half; reserve circles for garnish. Fill each cavity with a small scoop of chicken salad. For each caterpillar, top salad with reserved zucchini pieces and garnish one end with shredded carrots to create antennae.
