Grapholita funebrana is most damaging when larvae and they'll damage many species in the Prunus genus. Fruit will start to ripen faster than usual, and if cut open, you can sometimes find the larvae inside or dark excrement from where they have been feeding. They leave holes in the fruit, often causing a brown liquid to ooze from the wound and ultimately, make fruits inedible. They are most active during June-July.

Larvae feed on Prunus species and can make fruit inedible.
These moths can help support a variety of bird and bat species.


Adults: Mature moths are only around a centimetre long with a wingspan of 15mm. Their wings are brown with black mottled markings. Larvae: The grub-like caterpillars are a light red or pink or sometimes yellow with brown heads.


Fruit ripening quicker than normal. Premature fruit fall. Can see the larvae in the fruit when cut open. Discolouring of fruits. Emergence holes in fallen fruits. Oozy dark liquid emerging from fruits.

Biological treatment

If you notice fruits are discoloured, and they seem too soft or small when it's too early in the year for ripening, then they should be picked off and disposed of in the landfill waste.
