HEMEROCALLIS INSECT PROBLEMS
Flower thrips feed on flower buds and tips of the branches
killing the flower cluster. The scapes have corky
lesions.
Mites cause the leaves to turn yellow and have a dusty
appearance. Heavy infestations form fine webbing.
Slugs leave a slime trail which looks like part of the
leaf was varnished.
Japanese beetle can feed on the leaves and flowers.
