Answer 1

They are Vegetable Weevil larvae.  While some grubs are beneficial in the compost most all of them, including green rose chafers, will eat live plants if decaying plant matter isn't available.  You don't really want them in your potted plants.

Answer 2

hi :) thats a grub..''What exactly are they?

Well, their end result is those beautiful metallic green rose chafers'' see photo  http://maria.fremlin.org/cetonia_aurata/...    very pleased to find lots of grubs in my compost . They are the beetle equivalent of earth worms and help break things down, so they are very beneficial    http://maria.fremlin.de/stagbeetles/larv...
