Just been checking spring cabbage & PSB and today I found one green caterpiller ( who is no more ). Some of my leaves have had a good chomp as a result but I what I have noticed is that most of the leaves are scattered with tiny pin prick holes. Who or what is the culprit of these holes?
Probably flea beetles as they make tiny holes in leaves & really love brassicas xJane
Yes, flea beetle.
