The majority of the beetles found in Utah are deemed serious pests causing immense damage to plants and household properties. Those of the skin beetle family mainly infest homes found in woolen garments, furniture, flour, bird’s nest, cabinets, etc.
The state even has a stable population of the Velvet longhorn beetle. However, the Japanese beetle, a common pest in most states, does not thrive here in significant numbers. Another beetle worth mentioning is the ten-lined june beetle, mostly spotted in the morning, flying around lawns or gardens, making a hissing sound when disturbed.
The largest beetle species in Utah is the big black Prionus heroicus of the longhorn beetle family, while the skin beetles are the smallest.
