hi sair5412, weevil larvae look like fat maggots with an orange head. ive been infested with them a few times and they devastate everything. the weevil once mature is a dark grey beetle with a long snout and are very tough. they tend to go for anything in pots as they are warmer then they eat there way up the roots. your local garden centre will sell a solution that will kill them but you can not use it on edible plants, i prefer a natural approach of live nemetodes that are microscopic but eat the weevil grub. this can be purchased on the net from www.scarletts.co.uk and its the only thing that has worked for me.hope this helps
