The Argyresyhia conjugella, or the apple fruit moth, is seen to be a parasite for the apple growing communities in Finland, Norway, and Sweden. These moths are seed predators for the mountain-ash trees rowan (Elameen et al.). However, when there is a dip in the fruit produced by rowan every couple years in this region, the apple fruit moth finds a new host in the form of apples. Apples are not their desired host however and they communicate with the rowan seeds they prefer through odors (Knudsen et al.).
