Without seeing the image I would guess they are grubs from the Vine Weevil, as I have problems with the same. I sort through the corms, pick out the grubs and the birds have a feast. Then I also sort through the soil/compost of the pots they were grown in, and usually find a lot more grubs.
There is a Vine Weevil Killer you can water on, but I can't remember the name of, as I'm still in my nightclothes and it is out in the shed!!!

Agree with silver Surfer, very likely to be Vine Weevil grubs. I also have the problem this year. They burrow into the tuber. I found a dozen when lifting them and found 6 when I checked on them again yesterday. Provado Vine Weevil killer is the poison that kills them.

Definitely vine weevil grubs.

Thoroughly clean your begonia corms.  Wash and thoroughly dry them off.  Any with obvious damage to the corms are best discarded.  I,keep them then in paper bags until late winter and then place in shallow trays.

Thanks everyone, you have confirmed my suspicions. Will buy a vine weevil drench and hope that I can save some of the corms especially as some are 20 years old and lke old friends . I have only had the problem the last 2years and have probably been making it worse without realising by tipping the old compost on to the garden.

John innes composts seem less attractive to vine weevils.  Mpc are loved by those critters

Peat based ones are the worse for Vine weevil grubs.

Be careful with Provado, it still kills bees.

There is a difference between Provado insecticide and Provado Vine Weevil solutions.

They are still both neo-nicitinoides.
