Aphytis Wasp
A tiny golden-yellow parasitoid wasp that is the primary biocontrol agent of California red scale on citrus. It lays eggs beneath the scale cover where its larva feeds externally on the host.
Did You Know?
California produces over one billion of these wasps per year for release in citrus orchards.
Gum-Tree Pergid Sawfly
A robust Australian sawfly with a dark, polished body. Its gregarious larvae cluster on eucalyptus branches and produce a strong eucalyptus odor when disturbed.
