Tree limb drop season hits Sacramento
Oaks, willow, elm, ash, and eucalyptus are particularly susceptible to limb drop during the summer months.
Palo Verde Borers are root borers and are rarely seen above ground in the larval form. The adult form is a very large (3" to 6" long with antennae nearly as long as their bodies) conspicuous, dark brown cockroach looking beetle. Adults are active July through October. Immature larvae feed on living roots of Parkinsonia (Cercidium) (Mexican Palo Verde) and other non-native trees. Larvae spend up to three to four years underground feeding on roots. Over a 7 to 10 year period Palo Verde Borers will gradually kill a tree. The Palo Verde Borer larvae are large up to five inches long, grayish white to cream colored, with a large, distinct head regions and thick body.
