Because the bug and nymphs feed on the underside of the
Rhododendron and Azalea leaves, the damage caused is not often found
until considerable.
The adults insert their eggs into the leaf tissue of
the Rhododendron, and covers them with a varnish-like splodge.
A natural predator of the Rhododendron Lace Bug, is
the Lacewing. Please do not confuse, for the Lacewing - much
larger and lime green - is a very beneficial insect in the garden. (Lacewing).
Chemical control might be necessary - especially in
warm weather. Imidacloprid - Provado (systemic) or Bifenthrin -
(contact) can be used. Imidacloprid can also be applied to the soil as a
drench.
