Butterfly larva feeding device

The utility model relates to a butterfly larva feeding device. The butterfly larva breeding device is mainly composed of a breeding box and a residue receiving box. The device is composed of a stepping motor and a transmission structure. Thickening layers (2) are arranged on the upper middle portions of the two side faces, perpendicular to the front view direction, of the feeding box (1), a groove(3) is formed in the thickening layer (2) on one side and connected with a cylindrical rotating shaft (4) through a rotating head (9) in an engaged mode, the other end of the rotating shaft (4) is connected with a stepping motor (5), and the thickening layer (2) faces outwards. The main purpose of the utility model is to set the periodic movement of the stepping motor. The feeding box is driven to rotate slowly through the motor, the effect that larva excrement in the feeding box leaks out of grid holes in the side face and the bottom of the feeding box is effectively achieved, meanwhile, theinfluence on larva is red
