After A. D. Macgillivray ( State Mus. Bull. 68, 1903). laying habits of these beetles have been described in some detail by A. D. Macgillivray (1903) and A. G. Boving (1910). The female, living on the surface of a floating water-lily leaf, often eats out round holes penetrating to the lower leaf-surface and then thrusting the tip of her abdomen through, places her eggs in rows so as to form a circular or chordal area surrounding the hole ; such is the habit of the European Donacia crassipes and the North.
