Beginner Gardening: Bugs eating my dahlia blooms!, 1 by GardeningMommy

Help! This is my first summer gardening, so I have no idea what to do. I'm growing some Dahlia 'Duet', which is red with white tips. I keep finding that bugs are eating off the white tips just as they emerge from the bud! You can see from the picture that they eat the tips and then stop. After all the tips are gone, they then take a litle break before devouring all of the petals (I'll post another picture of that). Any ideas for keeping pesky pests away from my blooms?
