If they are not near a moult, a little puff of breath will generally dis lodge them. Some caterpillars, as Papilio Turnus, which spins a platform to which it retires after feeding, can best be fed upon a living tree out of doors, but must be covered with a gauze bag to keep off enemies. A piece of paper should be kept attached to each breeding jar or cage, upon which regular notes must be taken at the time, giving the dates of every noticeable feature, particularly the dates ofjthe moults and the changes which take place in the form and colour at that time.
