I have noticed a few leaves being almost totally eaten - they look like a
cobweb with the majority of the leaf having been eaten.

When I looked closely I found a number of small caterpillars - about 1mm to
2mm diameter - upto 1cm long.

Plain light green - with a yellowish light line down the body just above legs.


I have grown tomatoes for years - and have never seen them before.

Any ideas please?
