These beetles are eating my daylillies!!!! they are striped and very aggressive! HELP

Dear Dianne, you need a good spray for beetles...go to your local feed/supply store or plant supply store to get one, make sure it says it is for beetles...and spray weekly, especially after it rains. Fortunately, day lillies are tough, and will come back again next year, fresh and ready to delight you...but spray from the beginning of the budding to discourage these bugs.
