Palo Verde beetles are often the cause for a shriek due to their appearance and their menacing looking pincher mandable. But the truth is these beetles, which are also known as Palo Verde root borer (scientific name: Derobrachus geminatus), are harmless. These beetles do not sting and won’t pinch unless bothered or provoked.
Facts About Palo Verde Beetles
These beetles belong to the beetle family known as Cerambycidae, which are longhorn beetles. Almost all of the types of beetles belonging to this group have distinguishing long antennae.
The larva are creamy white in color, while adult Polo Verde beetles are often mistaken for large cockroaches. Adult beetles have long antennae and spines on their thorax. They have wings and they can fly. They are colored brown or black. The larvae (also called grubs) reach up to 5 inches long while adult beetles can grow up to 3 1/5 inches long.
They don’t just live in native trees, they can also be found in rose and olive plants, and Mexican Palo Verde trees. Females normally lay their eggs into the soil near tree roots. Once these eggs are hatched, the larva will bore into the roots of the trees and begin to feed on them. Adult males fly about in search of mates.
They are commonly seen living in the Phoenix and Tucson areas in Arizona.
Grubs eat the woody tissue of the root of trees. Adults beetles feed on the nectar of flowers or even fruits.
Grubs would live in trees for about 3 to 4 years before they become adults. On the other hand, adult beetles actually die as soon as after mating, thus making their life span to only just one moth.
Did you know that different species of beetles make up approximately 1/3 of all described animal species?
During the summer months when adult beetles are seen flying, motorcycle riders tend to drive more carefully. They also need to put the face shield down of their helmets. It is quite painful to be hit by big flying beetles in the face.
Palo Verde beetles were named after the Palo Verde tree, which is a beautiful desert tree with green bark. The Palo Verde tree is native to the Sonoran Desert. People say that if you dig up these trees, you are supposed to find several larvae eating away the tree roots. These beetles are often considered as pests.
They are Harmless
These beetles are large bugs. Adults can grow up to the size of your hand. They may startle you when you see one flying towards you.
They may give you a painful pinch, but they are not known to attack humans, only when they are bothered – these are peaceful creatures. These beetles are not toxic to humans and animals, and other living things. They are in fact good for your plants since they feed on nectar and fruit.
So, the next time you see these beetles, it is best to just let them be.
