Scientific name: Cydia pomonella.
The codling moth has a wingspan of about 1.2 to 1.8cm, and it's about 1cm long when at rest with the wings folded. It has a grey-brownish-pale color. This moth originated in Asia but has spread out to all continents except Antarctica. 

It’s the primary insect pest of pome fruits like apples and pears. The larvae not only feed on the leaves of these fruits but also on the fruits themselves. They are highly dependent on fruits as a food source. Consequently, these insects cause damage and loss since every fruit they munch on becomes unsellable.
