CLOSED: they are eating hole into hibiscus

Damascus, MD(Zone 7a)

These caterpillars are turning hibiscus leaves into nets. Can anybody please tell me what they are? If they are butterfly caterpillars, I will keep them there. At the moment, they are a bit less than half an inch in length. Thanks.

They're Hibiscus Sawfly larvae. If you grow hollyhocks, they'll go after them too. Big pest.

Thank you for the quick reply. I will get rid of them tonight.
