The grubs are guttiform. The width of the body is the biggest at the meeting of the notogaster and the prodorsum. Their frontal extension is not explicite yet. The rings of the notogaster are uniform, the ventrites and the tergites are not separated from each other, their number is equal. The size of body of the grubs is two times smaller than that of the adults. The edges of the tergites are saw-like in the side and the top view. The legs are shorter, their joints are hardly separated.
