Larva: Late instar larvae are approximately 8-9 mm in length with a pale-reddish abdomen. The head is yellowish brown with darker mottling. The prothoracic and anal shields are brown. Pinacular are moderately large. An anal comb is present with 4-6 teeth. Larvae may appear similar to those of many other species. Cydia pomonella larvae can be separated from G. packardi by the absence of an anal fork and their larger size. Larvae of
G. molesta are similar but generally larger. Larvae of
G. packardi and
G. prunivora are very similar, although the pinacula on the 8th and 9th abdominal segment are more prominent in
G. packardi, and the abdomen of
G. prunivora is more reddish, especially in preserved specimens.
