The food channel draws liquid and liquified food to the oesophagus by capillary action. The housefly is able to eat solid food by ...
Curculio glandium eggs are deposited in acorns by the adult weevil chewing channels into the fruit. The eggs are then released using an ovipositor, a long, narrow organ featured in female weevils. [2] These do not reach the acorn's embryo and are healed by the plant, sealing the holes and protecting the eggs from parasites.
