The note in the Canadian Entomologist for April 1903, by the late Prof. A. R. Grote, the one by Mr. J. Wm. Cockle, in the May number for the same year, and the one in the April 1904, number, all relating to this subject, have interested me greatly.

Over 25 years ago I observed and recoreded for the first, I believe, the destruction of the pupæ of our very common Samia cecropia by the Downy Woodpecker, by puncturing the cocoons and feasting on the juices of the occupant. The habit of the insect in attaching its cocoon firmly to and parallel with the twigs and smaller limbs of trees places them at the mercy of these birds, especially during that part of the year when the trees are devoid of foliage.
