There is some pest eating the leaves of my indoor red oxalis. I assume it is a larva or adult. I have already removed all the soil in the pot,washed the corms and re-potted them. New growth is still getting eaten and i have not seen any perpetrators on the leaves. I suppose I could do a night time search with a headlamp but I always forget once bedtime comes around. Besides I am now retired and not prone to partying after midnight! Any one have a similar experience and know what it is causing the damage?
