Moths in Arizona

You’ve probably noticed a lot of moths fluttering around your porch light lately. With the massive amount of rain we have received this year, it’s no wonder there’s been a huge influx of bugs. Don’t be annoyed. This is a good thing!

Arizona’s successful monsoon season turned the desert into a green oasis. The more rain we have, the more plant growth, which gives insects like moths and butterflies more food to eat and contribute to our ecosystem.

With a diverse topography, Arizona is considered one of the most insect-rich places in North America. Here is everything you need to know about these winged insects.


Moths do more than fly around and chew through fabric; they play an important role in our ecosystem. Insects like moths are food sources for other animals and pollinators for plants.

“Birds eat moths, bats eat mosquitoes, all these non-insect groups, mammals, reptiles and amphibians, they feed on insects. And so, they’re all connected with each other,” said Gene Hall, insect collection manager at the University of Arizona in Tucson, Arizona.

The insects that feed on the plants also act as natural pruners to the flowers and plants. They typically do not damage the plant to the point of killing it because they will have to find another food source.

Arizona is home to hundreds of species of moths. The most common moths are hawk and sphinx moths. These moths have long narrow wings and thick bodies. They have the longest tongue of any other moth. The caterpillars of this species feed on wild grape leaves. 

Bent-line carpet moths are another common species in Arizona. A bend can be seen in the dark colors by the wing edges. Males are mostly gray while females have darker colors. Their coloring makes it difficult for predators to see them because they can camouflage in tree bark.

Giant silk moths are seen in higher elevations like Sedona and Flagstaff. These moths are usually known for their size and range in size from 40 to 50 mm (about 2 inches). Silk moths draw their name from the silk they spin for their cocoons.

Moths are nocturnal meaning they use the light from the moon and stars to navigate their way. Streetlights and lights from our home are similar light sources.


Hall suggests taking the time to observe the insects in their natural habitat. They won’t be here for long and you may learn something new.

To get rid of moths, adapt your surroundings to make your home less moth-friendly. Turn off exterior and interior lights when not in use. Replace bright lights with yellow bulbs. Make sure there are no holes or gaps in screens and windows.

Will We Have Enough Water?

Water conservation is common practice in this very dry state. If you’ve lived in Arizona for any amount of time, you know we have a declining water supply.

But what measures are we taking to ensure enough water for decades to come?

Carbon-Free Electricity

Arizona Public Service (APS) is committed to carbon-free electricity. Since they are amongst the only companies that received a double-A score for their climate and water stewardship, they have a goal by 2050 to be 100 percent clean and carbon-free.

Carbon-free energy is the energy that is produced by generating no carbon emissions; the thing our cars emit. Hydroelectric plants are one of the ways Arizona is using this type of energy. As the water flows into the dam, it flows through a narrow pipe then pushes against turn blades in a turbine to spin a generator and produce electricity. The Hoover Dam and the Glen Canyon Dam were constructed for such resources. Our water supply comes from these dams through our canals. Learn more about our canals HERE.

Battery Energy Storage

The APS utility has been adding battery energy storage to its solar plants and expanding its renewable energy. They have signed an agreement that purchased 200 megawatts of additional wind energy. This has helped reduce the amount of groundwater consumption by 22 percent from 2014 to 2019. This utility is also used at Palo Verde Generating Station, the largest generator of carbon-free electricity in the U.S.


The Salt River Project (SRP) has created the Four Forest Restoration Initiative, which replenishes the state’s water supply through a massive public-private reforestation. Reforestation helps with climate change. More trees mean less heat. They absorb the carbon dioxide that would otherwise be put back into the air. If the temperatures can stay consistent and lower, less energy would be used. This allows SRP to refrain from tapping into more water consumption that’s used for energy.

Plan in Advance

EPCOR is the proven leader in managing our water supply. They have secured up to 5.87 billion gallons of water supplies by signing an agreement with Maricopa Water District. This adds to the amount of surface and groundwater offered to Valley residents.  

Join the Cause

Be conscientious and use common sense when using water. Phoenix is now considered to be the hottest city, according to national climate data. With heat comes less water. But if you are practicing conservation, you are headed in the right direction.

We all have to share this desert and showing a little care can go a long way.
