Hi Marcie,
Thank you for your question about your plant leaves being eaten. There are many insects that could be causing the damage. Without photos I cannot determine what insect is causing the problem.

The following publication describes some insects and their damage:
Common Insects that Cause Plant Damage in Central Oregon | OSU Extension Service (oregonstate.edu)

I recommend you contact the Plant Clinic at the OSU Deschutes County Extension in Redmond. You can call the phone number listed below, or send photos of the damage and your question to <personal data hidden>

The person on duty will review your information, conduct necessary research, and contact you with findings and management options.

The Deschutes County Extension Service Office is located on the fairgrounds in Redmond, near parking lot J.

Summer Hours: Monday through Thursday, 9:00 to 5:00 pm, Friday 9:00 am to 1:00 pm.

Phone:<personal data hidden> x79630

We always welcome your home garden questions at the OSU Plant Clinic.
