FOLIAGE-CHEWING INSECTS
Leaf-Feeding BeetlesLeaf beetles and the adults of certain weevils chew holes in foliage
or skeletonize leaves. Heavy infestations of elm leaf beetle can
cause serious damage to susceptible elm species. In general, leaf
feeding by most beetles or weevils is not harmful unless a tree is
repeatedly defoliated.Elm leaf beetles are small, yellow-green, and marked with
black, longitudinal stripes. Their larvae are dull and yellow-
green, and resemble small caterpillars.
Eucalyptus tortoise beetle adults and larvae chew notches in
the edges of eucalyptus leaves and may consume entire leaves.
Weevil adults chew irregular notches in the edges of leaves.
What to DoProvide adequate but not excessive irrigation to keep trees
healthy and vigorous.Most leaf beetles do not cause enough damage to warrant the
use of insecticides.When planting, choose elms that are resistant to elm leaf beetle
and rhododendrons that are resistant to weevils.
Decide to tolerate some degree of defoliation before you make
any insecticide applications.Where elm trees are seriously damaged, you can apply a trunk
banding of a persistent insecticide or a soil application of imi-
dacloprid. See Pest Notes: Elm Leaf Beetle for details.
To manage weevils on shrubs, pick off and destroy adults and
trim back any branches that provide a bridge to other plants
(the adults cannot �y). Soil-dwelling larvae can be controlled
with bene�cial nematodes.For More Information (See “Suggested Reading” on

BENEFICIALS
General Predators
Many of the insects found in gardens and landscapes are consid-
ered bene�cial because they feed on pest insects and mites. The
term general predator is used for those species that feed on a vari-
ety of different pest species. Besides insects such as those shown
here, spiders are important general predators in the landscape.
Syrphid �y larvae are legless maggots that consume aphids and
other soft-bodied insects. Adults resemble honey bees or small
yellowjackets and are often seen around �owers, where they
feed on pollen and nectar.
Lacewing larvae feed on many different soft-bodied insects and
mites. Adults are often seen around light sources at night. Adult
food includes insect honeydew and plant nectar. Adults of some
species (Chrysopa spp.) also feed on small insects.
Soldier beetle adults, also called leatherwings, feed on aphids
and pollen. Larvae live in the soil, where they feed on insects
and other arthropods.
Both immature and adult minute pirate bugs are very small and
feed on mites, thrips, and insect eggs. Immatures are pear
shaped and yellow or reddish brown.
What to Do
To
protect bene�cial insects, rely on nonchemical pest control
methods such as squashing, trapping, washing off, or pruning
out pest infestations.
Avoid using broad-spectrum pesticides such as organophos-
phates and pyrethroids.
Include �owering plants in your landscaping to provide pollen,
nectar, and shelter for bene�cials.
Control insect-tending ants with baits and use barriers to keep
them off landscape plants. Ants drive predators away from aphids
and other honeydew-secreting insect pests.
