CODLIN MOTH AND GRUB. monana of Linnreus, fig. 177, has become a sad pest to the Ameri- Fig. 177. can orchardists, and by Downing is said to have been introduced to that laud of apples from Eu- rope. It appears in the early worm- eaten apples and pears in the form of a reddish-white grub, and causes the fruit to fall prematurely from the tree. It is equally destruc- tive in Europe, and is very gene- rally distributed; perhaps there is no garden in which its appearance has not been recog- nised. The follow- ing description of it is from Kollar's work on insects, translated from the German by J. and M. Loudon : " This moth is to be seen in the evening, usually in the beginning of May, on the apple and pear trees, busily engaged de- positing its eggs either on the calyx, or in the hollow part of the fruit at the stalk end. It appears to prefer apples to pears—at least more grubs are found in the former than in the latter, when both sorts of fruit are plentiful. It in- variably selects the finer sorts of this fruit, knowing instinctively that they will be the most palatable to its future progeny. In favourable weather the little grubs are hatched in a few days, so that in May apples and pears are found infested by them. At first the grub is white, with a black head and collar, and black slanting double dots, which run in four rows from the head to the abdomen. It afterwards becomes more of a flesh colour, the head and collar turn- ing brown, the dots grey and indistinct. It is fully grown in three or four weeks, as its food never fails. It now leaves the fruit, whether it be still hanging on the tree or has fallen off, and selects for itself a secure place on the stem of the tree to spin its cocoon and become a pupa. It usually chooses the rents and seams of the loose bark, hollows itself out a chamber, and spins a white web over itself, intermixing some of the loose bark with it. The little grub be- comes a pupa immediately i
