Small clear resin-like drop on plum fruits

My plum tree fruits have small, clear, resin-like drops on them, any idea what could be causing this? See picture below.

    Aphids pierce the fruit and it exudes a resin.

    It's resin!  The tree produces it as a defence and to help heal itself.  It's the tree equivalent of a human scab.  As fidgetbones said, the most likely cause is that bugs pierced the skin of the fruit.

    A trowel in the hand is worth a thousand lost under a bush.

    Hi, I'm fairly certain that peach borer only occurs in the USA and Australia etc - I haven't heard that it's a problem in the UK and can't find reference to it having arrived here .... 

    So that's one less thing to worry about image
