These represent some of the largest and most visually striking beetles in Utah. While they can be intimidating due to their size, they are a natural part of our mountain and desert ecosystems.
Longhorn BeetlesNamed for their incredibly long antennae, which can be longer than their actual bodies. They are often spotted near Utah's canyon parks.
Scarab BeetlesThese are robust, oval beetles. The most famous Utah scarab is the Ten-Lined June Beetle, which is large, striped with white and green, and makes a distinct "hissing" sound when touched.
The GrubsScarab larvae are the "C-shaped" white grubs found in Utah lawns that eat grass roots and attract skunks or raccoons to your yard.
Wood BorersLonghorn beetle larvae (Roundheaded Borers) spend their lives tunneling through dead or dying wood. If you bring firewood inside, you might hear them "chewing" inside the logs.
The HissThe Ten-Lined June Beetle has a unique defense; it forces air out of its spiracles (breathing holes) to create a loud hissing sound to scare off birds and curious pets.
Night FlightBoth types are clumsy fliers. They often "thud" against windows or patio doors at night as they are drawn toward the light.
Is that giant beetle with the long 'horns' dangerous?No. While they have strong mandibles meant for chewing wood, they are not aggressive toward humans. They are simply attracted to the lights of your home.
Why is my lawn dying in patches?This is often caused by the "White Grub" stage of Scarab beetles. They eat the roots, causing the grass to pull up easily like a piece of carpet.
