Symptoms
|
Root weevil tends to concentrate on new or current growth. Most damage will be noticed on rhododendrons, azalea and viburnum. Larvae hatch from eggs laid in the soil or, in the case of the obscure root weevil, from eggs laid on leaves. These munchers spend the winter eating plant roots, weakening them. In mid-spring, the young mature into adult offenders, damaging plants by climbing up the trunk and eating the leaves, usually at night. They make a characteristic notching pattern, on the edges of the leaves. Most root weevil species are all female so they reproduce by cloning in the summer.
