Finely crush graham crackers. Add butter and 2 tablespoons of the sugar and mix until all crumbs are moist. Press into bottom and up side of a 9-inch round springform pan.
In a large bowl, beat together cream cheese and yogurt. Beat in remaining 1 1/2 cups sugar, lemon juice and zest. Add eggs and beat until smooth. Rinse cup blueberries; place in a small bowl. Sprinkle with 1 tablespoon of the flour; toss to coat. Fold berries and any flour in the bowl, along with remaining 3 tablespoons flour, into the cream cheese mixture.
