Preheat oven to 425 degrees F. Lightly oil a 9-inch baking dish or coat with nonstick spray.
In a large bowl, combine cream cheese, mayonnaise and sour cream. Stir in artichoke hearts, crab meat, 1/2 cup fontina cheese, pepper jack cheese, green onions and Worcestershire; season with salt and pepper, to taste.
Spread crab mixture into the prepared baking dish; sprinkle with remaining 1/2 cup fontina cheese.
Place into oven and bake until bubbly and golden, about 20-25 minutes.
Serve immediately.
