Why Do Desert Sun Spiders Chase?

Share

Understanding Desert Sun Spiders


Desert sun spiders, also known as camel spiders, wind scorpions, and solpugids, are large, hairy arachnids found in deserts worldwide, including Borrego Springs, California. Known for their speed and aggressive appearance, they are often mistakenly believed to chase humans.


Misconceptions About Chasing


Despite popular belief, desert sun spiders do not chase humans. They are skittish and only attack if they feel threatened. They might appear to chase people because they are attracted to light and shade. When you stand in the desert sun, a sun spider may mistake your shadow for a shade source and run toward it.

Curiosity is another reason why these spiders might seem to be chasing people. They are often attracted to movement but typically lose interest and wander away if the person remains still.


Encountering Sun Spiders in Borrego Springs


If you see a desert sun spider in Borrego Springs, there is no need to worry. It is likely attracted to light or shade or simply curious about you. Standing still will usually cause it to lose interest and move away.


Benefits of Desert Sun Spiders


Despite their fearsome appearance, desert sun spiders play a crucial role in the desert ecosystem:


  • Predators: They help control insect populations by eating beetles, scorpions, and other sun spiders, benefiting other animals in the desert.
  • Decomposers: When they die, their bodies decompose and release nutrients into the soil, helping to fertilize it and make it more productive for plants.


While they may not be the most lovable creatures, desert sun spiders are essential for maintaining the balance of the desert ecosystem. Next time you see one in Borrego Springs, let it go about its business—it’s more beneficial than you might think.


Tips for Avoiding Desert Sun Spiders


If you are concerned about encountering desert sun spiders in Borrego Springs, here are some tips to avoid them:

  • Avoid hiking or camping in areas where these spiders are common.
  • Wear long pants and sleeves when in the desert.
  • Use a flashlight at night to avoid stepping on them.
  • If you see a desert sun spider, do not approach it. Stand still, and it will eventually wander away.

By Karen Pearlman, East County Magazine July 20, 2026 (Ramona) — San Diego County’s aerial firefighting capabilities have been boosted with the reopening of the modernized Ramona Air Attack Base, where state and local officials on Monday morning unveiled nearly $20 million in upgrades designed to get aircraft back into the air faster and expand around-the-clock wildfire response. The renovated base at 2498 Montecito Road now houses a new 4,000-gallon CAL FIRE C-130 Hercules air tanker, a night-capable S-70 CAL FIRE Hawk Helicopter, two S-2 air tankers and an OV-10 Air Tactical aircraft. The group of aircraft is creating what officials called one of California’s most advanced aerial firefighting hubs. The base’s aging infrastructure has been replaced with a modern retardant mixing plant capable of storing 20,000 gallons of fire retardant, redesigned aircraft loading bays that dramatically reduce turnaround times, and expanded ramp space to accommodate additional air tankers during major wildfire incidents. “This base is a regional asset,” CAL FIRE/San Diego County Fire Chief Tony Mecham said at a press conference that was livestreamed on YouTube . “When there is smoke in the sky, the citizens don’t care what color the fire engine is or what patch is on the uniform. They just want people to show up quickly.” The improvements come as California faces increasingly destructive wildfire seasons fueled by hotter temperatures, prolonged drought and more extreme weather conditions. CAL FIRE Director and Fire Chief Joe Tyler said the Ramona facility reflects years of investment in modernizing California’s aerial firefighting fleet. Over the past two years, CAL FIRE aircraft have flown more than 11,500 flight hours annually while maintenance crews logged more than 90,000 hours keeping aircraft mission-ready, Tyler said. Among the most significant additions is the C-130 Hercules air tanker, capable of dropping 4,000 gallons of fire retardant — more than three times the capacity of CAL FIRE’s traditional S-2 air tankers. The aircraft is part of the state’s new fleet of converted military transport planes that entered service beginning in 2024. Also based in Ramona is the county’s new S-70 Firehawk helicopter, which can perform water drops after dark — a capability officials said is already proving invaluable. It has an integrated 1,000-gallon water tank with hoist rescue capability and the ability to transport helicopter crews into remote terrain. San Diego County Board of Supervisors Chair Terra Lawson-Remer pointed to last week’s Thorn Fire, where the Firehawk flew nighttime suppression missions that slowed the fire’s progression and helped prevent flare-ups the following morning. “Our days are getting hotter, our nights are getting warmer, the winds are stronger and fuels are drier,” Lawson-Remer said. “Wildfire does not stop when the sun goes down.” She urged residents to prepare for wildfire emergencies by signing up for emergency alerts, planning evacuation routes and heeding evacuation orders when issued. For East County backcountry communities, the upgrades could mean quicker aerial response to fires threatening homes. Aircraft assigned to Ramona regularly respond throughout the county. Mecham twice shared the importance of coordinated and consolidated efforts between firefighting agencies across the county. “We fight fire without boundaries and without egos,” he said. Mecham said the modernization project focused on improving efficiency as much as expanding capabilities. Previously, air tankers were forced to maneuver awkwardly into a single retardant loading area, creating backups during major wildfire incidents. The redesigned facility features three drive-through loading pits that allow aircraft to taxi in, reload and immediately return to the fire. “The S-2s can reload in about two to three minutes,” Mecham said. “The C-130, under 10 minutes, it’s on the ground here at Ramona before it’s back in the sky responding to the next fire.” The expanded ramp now allows up to six air tankers to stage simultaneously. During last week’s Thorn Fire, officials said 11 air tankers were assigned to the incident, underscoring the need for increased loading capacity. Additional improvements are in the planning stages. Construction is expected to begin next year on a 14-person barracks to support future 24-hour operations, along with further expansion of the helicopter facilities. Monday’s ceremony also highlighted the historical significance of the Ramona Air Attack Base, which opened in 1957 as CAL FIRE’s first aviation base. While the facility received new buildings in 2000, much of its underground infrastructure — including water lines, electrical systems and retardant delivery equipment — had remained unchanged until the recent reconstruction. San Diego County Supervisor Joel Anderson, who lives in the fire-prone area of Alpine, thanked leaders for their understanding of the importance of the Ramona airport site… “not just in San Diego County but for Southern California in general.” “CAL FIRE has been an essential partner for the County Fire, providing joint fire protection in emergency services for more than 1.7 million acres,” Anderson said. “Since CAL FIRE’s creation in 2008, the Board of Supervisors have invested over a billion dollars into fire protection in emergency medical services. “In the years since we created County Fire, we have also expanded our partnership in collaborations. In 2022, CAL FIRE successfully collaborated with the Ramona Municipal Water District to establish the Ramona Airport as a hub for aerial firefighting teams, in addition to replacing fire engines and adding a third ambulance, which was so important to the backcountry and to all my constituents.”

Don't Miss These Summer Night Sky Events
June 21, 2026
Prepared with information from ABDNHA's Dark Sky resources, Michael Poirier, Astrophotographer, and the Sky Calendar from Michigan State University. Learn more about Borrego Springs dark skies at: https://abdnha.org/darksky/sky / Note: You can subscribe to the Sky Calendar from Abrams Planetarium, Michigan State University, 755 Science Rd, East Lansing, MI 48824. Borrego Springs offers some of the darkest skies in Southern California, making summer an excellent time to observe the Milky Way, planets, meteor showers, and other celestial events. Here's what to look for in June and July 2026. Early June Sunrise: 5:38 a.m. Sunset: 7:50 p.m. PST Day Length: 14 hours 12 minutes June Highlights June 1 (Monday) Venus and Jupiter appear within 8° of each other in the west-northwestern sky after sunset. June 3–16 Milky Way viewing conditions are excellent, with dark, moonless skies after nightfall. The Milky Way rises at 10:57 p.m. on June 7 and as early as 10:30 p.m. on June 14. It remains visible for up to 4 hours and 29 minutes. June 6–13 Grand Canyon Star Party, Arizona. Learn more at www.grandcanyon.org . June 11 (Thursday) Venus, Jupiter, and Mercury span their shortest angle in the evening sky, just 13.2° apart. June 15 (Monday) New Moon — one of the darkest nights of the month for stargazing and astrophotography. June 15 (Monday) Mercury reaches greatest elongation, 24.5° from the Sun, making it the best evening appearance of the year shortly after sunset. June 21 (Sunday) June Solstice marks the beginning of summer in the Northern Hemisphere. It is the longest day of the year with 14 hours and 20 minutes of daylight. June 22–July 2 June Bootids Meteor Shower. June 29 (Monday) Full Moon rises at 8:17 p.m. and sets at 5:04 a.m. June 30 (Tuesday) Asteroid Day. Early July Sunrise: 5:41 a.m. Sunset: 7:59 p.m. Day Length: 14 hours 18 minutes July Highlights July 5 (Sunday) The Milky Way rises at 9:38 p.m. and remains visible for 3 hours and 58 minutes. July 12 (Sunday) The Milky Way rises at 9:34 p.m. and remains visible for 3 hours and 35 minutes. July 14 (Tuesday) New Moon — ideal conditions for stargazing and astrophotography. July 15 (Wednesday) Mercury reaches greatest elongation, 24.5° from the Sun. July 28–29 (Tuesday–Wednesday) Delta Aquariids Meteor Shower peaks. July 29 (Wednesday) Full Moon rises at 8:17 p.m. and sets at 5:04 a.m. The Planets and the Milky Way in June Evening Planets Venus and Jupiter dominate the western sky after sunset throughout June. Around June 8–9, the two planets appear in conjunction, creating a striking close encounter in the west-northwestern sky. Venus, often called the "Evening Star," shines brilliantly as it moves from Taurus toward Gemini and climbs higher in the evening sky each night. Jupiter remains nearby and is also easily visible. Mercury becomes visible low in the western sky during the second half of June. June 15 offers the best viewing opportunity, as Mercury reaches its greatest elongation and highest apparent position above the horizon. Morning Planets Saturn and Mars are visible before sunrise. Mars remains low in the east-northeast, while Saturn rises higher from the east to east-southeast. Early June provides a chance to see the two planets relatively close together. Summer Milky Way Summer is the prime season for viewing the bright central core of the Milky Way. From June through August, the galaxy's core rises in the southeastern sky and becomes one of the most spectacular sights available to dark-sky observers. June Bootids Meteor Shower The June Bootids occur annually from June 22 through July 2 and peak around June 27. Most years produce only one or two meteors per hour. However, this shower has occasionally surprised observers with dramatic outbursts. In 1998, rates briefly reached approximately 100 meteors per hour. The shower originates from debris left by Comet Pons-Winnecke, which orbits the Sun every 6.3 years. June Bootids are known for their unusually slow speed, entering Earth's atmosphere at approximately 14 kilometers per second. Asteroid Day – June 30 Asteroid Day is a United Nations-sanctioned global awareness campaign held annually on June 30. The event educates the public about asteroid impacts, planetary defense, and ongoing research into near-Earth objects. The date commemorates the Tunguska Event of June 30, 1908, when a massive airburst explosion flattened approximately 830 square miles of Siberian forest. The blast is estimated to have released energy equivalent to between 3 and 50 megatons of TNT, making it the largest recorded impact event in modern history. For more information, visit www.un.org. Delta Aquariids Meteor Shower The Delta Aquariids meteor shower peaks on the night of July 28 and the morning of July 29. This annual shower can produce up to 20 meteors per hour under ideal conditions and is associated with debris from Comets Marsden and Kracht. The shower runs from July 12 through August 23 each year. Unfortunately, the 2026 peak coincides with a Full Moon, which will wash out many fainter meteors. Patient observers may still catch some of the brighter meteors throughout the night. The meteors appear to radiate from the constellation Aquarius but can be seen anywhere in the sky.

Regional event celebrates the night sky, science, and dark sky preservation Borrego Springs residents who enjoy stargazing, astronomy, and protecting the night sky may want to mark their calendars for the 2026 San Diego Dark Sky Festival , scheduled for August 15 from 3 p.m. to 11 p.m. at Julian Union High School in Julian. The festival will feature distinguished speakers, telescope viewing, hands-on activities, educational exhibits, and opportunities to learn more about the growing dark sky movement throughout San Diego County. The event is organized by DarkSky San Diego County and regional partners committed to reducing light pollution and preserving access to natural darkness. Activities are designed for families, students, amateur astronomers, and anyone interested in the night sky. Festival organizers describe it as a celebration of stars, science, and community. For Borrego Springs residents, the festival highlights a cause that has become part of the community's identity. Borrego Springs was California's first International Dark Sky Community , earning recognition for its efforts to reduce light pollution and preserve exceptional night-sky viewing. Julian followed with its own International Dark Sky Community designation in 2021, creating a network of dark-sky advocates in San Diego County's backcountry. The festival also showcases the growing regional movement to protect dark skies. Organizations from Borrego Springs, Julian, Fallbrook, Mission Trails Regional Park, and the Laguna Mountain area are working together to promote responsible lighting and preserve natural darkness for future generations. Visitors can expect telescope viewing, astronomy demonstrations, educational booths, and presentations on the importance of natural darkness for wildlife, human health, and energy conservation. Similar festivals have drawn large crowds and provided opportunities for the public to experience some of Southern California's best night skies. For many Borrego Springs residents, the event offers a chance to connect with neighboring dark-sky communities while celebrating one of the region's greatest natural resources—the star-filled skies that make both Borrego Springs and Julian special destinations for stargazing. ------------------ Fun Local Fact: K-RAM 90.5 FM at 730 Christmas Circle recently received a Night Sky Friendly Business Certificate of Merit from the Borrego Springs Dark Sky Coalition. The building also houses a Dark Sky visitor center and Borrego Valley Realty, where realtor Mary Watkins helps visitors learn more about protecting Borrego Springs' famous night skies.

One of the things that makes Borrego Springs special happens after the sun goes down. Borrego Springs became California's first International Dark Sky Community in 2009 and was only the second community in the world to receive the designation. The certification recognizes communities that actively work to reduce light pollution and protect the night sky for future generations. Earlier this year, a Dark Sky presentation highlighted K-RAM 90.5, XL Fuel Stop, and Borrego Holiday Homes as examples of businesses using responsible lighting practices that help preserve Borrego Springs' internationally recognized night skies. Ram Media Foundation Updates Exterior Lighting The Ram Media Foundation building at 730 Christmas Circle, now home to K-RAM 90.5, the Borrego Sun, and Borrego Valley Realty, removed older unshielded, high-lumen fixtures that reflected light outward around the property. The updated lighting includes shielded fixtures and a downward-facing reflector along the front walkway. These improvements provide lighting where it is needed while reducing unnecessary glare and light escaping into the night sky. XL Fuel Stop Reduces Sky Glow XL Fuel Stop was highlighted for using fully shielded lighting that directs light where it is needed instead of into the night sky. According to the presentation, a bright light mounted atop a high pole was turned off, and after-hours lighting levels were reduced. These changes help minimize sky glow while maintaining safety and visibility for customers. Borrego Holiday Homes Improves Efficiency Borrego Holiday Homes was highlighted as another example of responsible lighting practices. The property reduced excessive brightness by lowering lumen levels and using shielding that directs light downward. The result is reduced glare, improved efficiency, and lighting that better serves guests without unnecessarily illuminating the surrounding area. Why Dark Skies Matter According to the Borrego Springs Dark Sky Coalition, light pollution is the human-made alteration of outdoor light levels from those occurring naturally. Excessive brightness can create visual discomfort, affect wildlife behavior, disrupt human circadian rhythms, and diminish our ability to see the stars. Responsible lighting does not mean eliminating outdoor lighting. Instead, it means using the right amount of light, directing it where it is needed, and avoiding unnecessary brightness. The Borrego Springs Dark Sky Coalition was formed in 2007 by local residents seeking Dark Sky certification. Facilitated by the Anza-Borrego Desert Natural History Association (ABDNHA), the coalition continues to educate residents, businesses, and visitors about responsible lighting practices that help preserve Borrego Springs' exceptional nighttime environment. The improvements made by K-RAM 90.5 , XL Fuel Stop, and Borrego Holiday Homes demonstrate that protecting dark skies can go hand in hand with safety, efficiency, and good business practices. For residents and visitors alike, these efforts help ensure that Borrego Springs remains one of the best places in Southern California to experience a sky filled with stars.

A recent KPBS report shared heartbreaking news: an endangered Peninsular bighorn sheep was found dead after becoming entangled in concertina wire near the U.S.-Mexico border in the Jacumba Wilderness. The story highlights growing concerns from wildlife biologists and conservationists about how border fencing and razor wire can affect protected species, including bighorn sheep, mountain lions, and wild horses. Wildlife biologist Christina Aiello has been among those warning that barriers can cut animals off from food, water, and safe movement corridors. This issue matters to Borrego Springs and the surrounding desert region because Peninsular bighorn sheep are part of our shared desert landscape. Protecting wildlife movement, water access, and habitat is essential to the long-term health of the Anza-Borrego region.
