Geranium. Leaves eaten?

[Astra99]

Hi

I am hoping someone with greener fingers than mine will be able to help. We have five pots in a line containing geraniums. In two of the pots the leaves appear to have been eaten by something, but there is no evidence of slug or snails. Under the stones (on which the pots stand) is a plastic membrane. I have attached a JPG of one of the two affected pots.

Thanks in advance.

they look like classic slug bites

they are not a common choice for slugs or snails, looks like caterpillars to me

^^^^^ This. Don't look like slugs/snails to me.

Thanks to everyone who answered. I have put some slug pellets in the affected pots for the time being. Does anyone have any other suggestions or remedies?

Don't think it will be slugs,more than likely a caterpillar,have a good look in and around the plants the blighters will be there some where.
