Other pests with which fruit tree tortrix moth may be confused
Larvae of several leaf-rolling tortrix moths are very similar and are difficult to distinguish from each other.
Larvae of the summer fruit tortrix moth, Adoxophyes orana, occur commonly in orchards in the UK, especially in the south and east, and are particularly difficult to distinguish from those of the fruit tree tortrix moth.
