A few days ago, I noticed something was eating holes in my brug leaves, but couldn't find anything. Next day, more holes, no bugs. Yesterday morning I was looking out and saw a little bird studying my brug intently. It jumped down into the pot and scanned the underside of the leaves. Then quick as could be it grabbed a small green caterpiller (I think) in its beak and happily hopped away to eat breakfast. Problem solved.

Wish I had a picture.

Don't need pesticides when you get service like that from your feathered friends.
