Apple maggot Rhagoletis pomonella adult with egg, maggot, and pupa. The maggot has two black feeding hoots. The adult has white abdominal stripes, a white spot which is instantly recognisable, and a blackish "F" shape on the wings.

Plum weevil or Curculio Conotrachelus nenuphar adult showing rostrum, which is used to peel back a flap of fruit for oviposition. Also shown is an egg, grub, and pupa. Apple fall is common, if the apples grow too fast the grubs can be crushed by the expanding cell walls of the fruit.

...and these are the culprits. The #Plumweevil can affect up to 85% of an apple crop and also attacks stone fruit like cherries and plums. The #Applemaggot #fly affects a wide range of plants and each female lays up to 200 eggs.
