Palo Verde Beetle Description

You’re probably wondering, “why would I want to know more? They’re disgusting!”  Well, although they are pretty big, they actually look pretty cool. They have a few spikes on their outer body with a unique texture for their hard shell. Their antennae uniquely look like long horn cows, which is why the Palo Verde Beetle gets classified under the long horn beetle family.

How’d They Get Their Name?

The Palo Vedre Beetle gets it’s name from the Palo Verde Tree. These beetles lay their nests at the feet of these trees as well as other trees, but primarily the Palo Verde trees. Palo Verde trees are quite beautiful, having a unique yellow coloring that flowers the whole tree. These flowers branch out in a way that almost makes the tree look like a big yellow bush that helps attract many pollinators. These trees serve a big purpose in helping saguaro cacti as they will,  at times, shade them to strengthen their growth.

Though Palo Verde Trees are beautiful, unfortunately, these beetles are not found only at them, they range to other trees as well. This means they could be found closer to your home than you think.

Do They Bite?

Now, the question you’ve been waiting to be answered, are they harmful? These 6 inch beetles that can fly, if that’s not bad enough, nest around trees, and put cockroaches to shame actually are not known to bite or sting at all. After you’ve sighed with relief, you should know that  as great it is that they don’t bite or sting, they do, however, lay nests that are not good for the trees they choose to inhabit.

That’s right, surprisingly, the most dangerous things these beetles do is in their larvae state. The Palo Verde Beetles are in their larvae state for about 3-4 years. When they mature and mate they only live as fully adult beetles for about a month!

Are They Harmful?

The problem is that the larvae slowly eat away at the roots of the trees which will eventually kill the host tree. By the time you find their nests it may be too late. The best way to keep your trees alive in these situations, is to take really good care of your trees. Water them, keeps animals away from them, etc. and they should be able to fight them off.  As you do that, less beetles will come by your house.Unfortunately, that doesn’t always help get rid of them all.
