Those look like eggs and since the leaves are eaten I would assume that they were caterpillar eggs. And the best way to eliminate caterpillars is with a Bt spray.
Greetings, welcome to the Forums.
The marks pictured are neither insects nor eggs of any kind. They are extra-floral nectaries, an innate part of the plant itself.
Such nectaries occur on the leaves of English Laurel (Prunus laurocerasus), and in various places on numerous other plants. The nectaries serve as food for one or more beneficial organisms that the plant wishes to attract. Often these are predatory insects, such as ants or wasps that will protect the plant from herbivory in order to protect their nectar source.
Schipka Cherry-Laurel (Prunus laurocerasus 'Schipkaensis'), also known as Skip Laurel, is a dwarf form of English Laurel collected near Schipka Pass in Bulgaria. Schipka Cherry-Laurel also has narrower leaves than typical English laurel.
