Two 24x36 cases stacked on top of each other to form a 3 x 4 foot flight.  This piece features the huge Morpho didius and the smaller Pearl Morpho (please see other images on our site).  For a lower cost option the Pearl Morpho can be replaced with half blue morphos or all blue morphos.  The white glider can also be used, probably a few more than the pearl as they are close in size but a little smaller than the Pearl.
