Every fall, one of nature's most spectacular phenomena takes flight in California - the annual migration of the monarch butterfly. These delicate insects make the incredible journey down from Canada and the Pacific Northwest to overwinter in the relatively balmy climes of coastal California. Their migration path covers thousands of miles, an astonishing feat for a creature that only weighs about half a gram.
The monarch's migratory cycle is nothing short of remarkable. Up to a billion monarchs will stream south from September through November, traveling up to 100 miles a day. The generation of monarchs that migrates is different from the ones that started the journey north in spring. These super-monarchs live for 6 to 8 months instead of just 2 to 6 weeks. Their incredible longevity allows them to complete the entire two-way migration over multiple generations.
Once they reach California, they converge by the tens of thousands on small groves of trees along the coast. These groves in Pacific Grove, Pismo Beach, Santa Cruz and elsewhere provide shelter and warmth for the butterflies to wait out the winter. Clinging to branches in massive clusters, they enter a state of dormancy. This seasonal roosting behavior isn't fully understood but seems to provide safety in numbers while conserving energy.
In spring, the monarchs become active again. After mating, the females lay eggs and the cycle begins anew as caterpillars hatch. This new generation makes the return trip north and along the way lays eggs that will become the next migratory generation. And so the incredible migration continues, year after year.
For lepidopterists and nature lovers, few sights compare with expansive monarch overwintering sites literally fluttering with activity. The vivid orange and black insects carpeting trees and fluttering through the air delight both scientists and tourists who flock to see them. Though fragile as individuals, together they create an impervious blanket that protects them from wind and rain.
Flutter By: Chasing Monarchs on a California Road Trip - Ideal Itineraries for Optimal Sightings
Timing is everything when it comes to witnessing the magical monarch migration in California. Plan your road trip between mid-October and mid-November for peak sightings of these fluttering wonders. Their numbers swell into the millions during this period as clouds of late arrivals join the masses already sheltering along the coast.
Most monarch groves don't open to visitors until November 1st to minimize disturbances. Plan to spend a few days exploring top sites like Pacific Grove Monarch Sanctuary, Pismo Beach Monarch Preserve, and Natural Bridges State Beach. Weekdays tend to be less crowded than weekends at these popular spots. Arrive early in the morning or in the late afternoon when the monarchs are most active. Cool, overcast days may inspire them to cluster tightly to stay warm. But bright sunny days bring welcome warmth that energizes them to take flight.
Venture down the coast to check out additional sites around Santa Cruz like Lighthouse Field State Beach and Francis Beach. Or head inland to Ellwood Bluffs just north of Santa Barbara. More monarchs congregate here later in November. There are also small roosts dotting the coast around Ventura and Los Angeles for southerly sojourns.
While fixed preserves safeguard main groves, monarchs often create transient roosts in trees throughout coastal towns. Spy on them by poking around eucalyptus groves or asking locals for tips. Quiet walking paths make impromptu viewing spots. Or simply keep your eyes peeled when exploring charming beach communities. From neighborhood parks to backyard gardens, monarchs can appear when you least expect them.
Embark from Los Angeles or San Francisco so city sightseeing can pad your itinerary between grove visits. Overnight stays in Santa Cruz or San Luis Obispo provide easy access to top sites. Luxury resorts like Ventana Big Sur nest you right among frequented groves. Most regions also offer budget-friendly hotels, motels, Airbnbs, and campgrounds.
Flutter By: Chasing Monarchs on a California Road Trip - Pacific Grove Landing Party
Perched on the edge of the Monterey Peninsula, Pacific Grove has been rolling out the welcome mat for migrating monarchs since the late 1800s. Back then, monarchs would arrive in such great numbers that they alighted on everything in sight. Roads, rooftops, fences - nothing was off limits to the indiscriminate insects. Amused locals dubbed November “butterfly month” as clouds of monarchs descended en masse. Newspapers chronicled their arrival and celebrations welcomed them to town.
Over the decades, Pacific Grove has continued the tradition of celebrating the monarch return. Each October, they hold a lively Landing Party right before the monarchs begin trickling in. Locals gather at Lovers Point Park dressed in orange and black finery. Face painting, butterfly arts and crafts, and monarch-themed treats add to the festive atmosphere. Musicians and dancers entertain as people eagerly await the monarchs.
When the first monarch sails in, the revelry crescendos. Cheers erupt, paparazzi cameras flash, and a symbolic red ribbon is cut. Chased by excited children, the butterfly embarks on a route dotted with nectar stations to help fuel its journey. The gentle insects follow cues along a specially designated “Butterfly Trail” through Pacific Grove's Pine Woods. For weeks after the Landing Party, residents keep watch for winged visitors in their yards and gardens. Temporary clusters coat trees and bushes as monarchs pause to rest and refuel. But the main attraction is the Monarch Sanctuary situated within a eucalyptus and pine grove near the coast.
From October through February, you can visit the Sanctuary and witness a true natural wonder. The signature clustering behavior peaks in November when masses of monarchs drape the grove like orange and black tinsel. Docents give free tours explaining the insects’ incredible migration and life cycle. Gaze up in awe as thousands of monarchs flutter overhead or cling to branches in colorful clusters. This protected haven provides both shelter and community for the overwintering insects. Many have traveled thousands of miles to reach its boughs.
Flutter By: Chasing Monarchs on a California Road Trip - Butterfly Buffets - What They Love to Eat
Though adult monarchs fuel their ambitious migration with nectar, their caterpillars have more particular palates. Understanding what these finicky eaters love to munch helps us support them along their extraordinary journey.
Milkweed takes center stage as the caterpillar's cuisine of choice. These wildflowers in the genus Asclepias contain toxic compounds that make monarchs poisonous to potential predators. But caterpillars have evolved to safely consume the plants and sequester the toxins in their own bodies for protection. There are over 140 species of Asclepias milkweeds native to North America. Regrettably, many have declined as prairie habitat dwindled.
Recognizing this threat to monarch survival, conservation initiatives encourage planting milkweed corridors across the country. Tropical milkweed varieties, while well-intentioned, may not promote migration. Some enthusiasts stick to local native species like California milkweed in the west. But non-native milkweeds are certainly better than no milkweed at all. Just uproot them after fall migration to avoid disrupting winter dormancy.
Though milkweed reigns supreme, caterpillars and butterflies sip nectar from diverse wildflowers too. Effective nectaring plants entice them with bright colors, abundant blooms, and accessible, tubular flower shapes. Native species suited to local soils work best. Some west coast favorites include asters, lupines, goldenrods, phacelias, ceanothus, and salvias like hummingbird sage.
Non-native flowering plants still offer nutrition. Buddleia, pansies, zinnias, and marigolds are tried-and-true butterfly buffet options. Certain tropical trees like lantana and cassia alata also produce heavy blossoms that butterflies flock to. Plant red, orange, pink, or purple flowers to attract the most monarch attention. They don’t see yellows or greens well.
Avoid modern flower varieties with fancy double blooms. Their nectar can be hard to access. And skip pesticide use which endangers butterflies. Also provide damp patches of dirt or add water features so butterflies can take moisture while feeding. Ultimately any pretty, pesticide-free flowers will likely lure in fluttering diners.
Flutter By: Chasing Monarchs on a California Road Trip - Photographing the Wings of Beauty
Capturing the ephemeral beauty of monarchs in flight presents a special photographic challenge. Unlike birds, butterflies can’t be counted on to return to the same perches. And the erratic nature of their flutter makes snapping that perfect shot tricky. But with some strategic techniques, you can frame gorgeous portraits of monarchs mid-journey.
First and foremost, shutter speed is key for crisp photographs of moving monarchs. Aim for speeds around 1/1000th of second or faster to freeze their wings during active flight. That typically requires shooting in shutter priority or manual mode. Aperture can float more - somewhere between f/8 and f/16 generally keeps the wings sharp while softly blurring the background.
Since light is critical, seek out bright spots in open groves. Position the sun behind you when possible for backlighting that makes wings glow. An overcast day with diffused light works great too. Early morning or late afternoon hours often provide ideal illumination when sunlight filters through at an angle.
Now comes the fun part - finding photogenic subjects. Scan trees and shrubs for resting monarchs that you can approach up close without disturbing their repose. Or observe clusters flying around flowers until one pauses to sip nectar. This presents a perfect opportunity for a portrait.
Patience wears many rewards when it comes to photographing wildlife. Sit and wait for monarchs to come to you. Have your camera ready to shoot multiple frames when one wanders into the scene. Capturing take-off or landing moments provides exciting action sequences. You can literally hear the click of shutter mirroring the flap of wings.
Telephoto zoom lenses allow framing tight shots of individual monarchs. But don’t forget wide angle lenses to capture the big picture of swarms spotting eucalyptus groves. An intermediate 80-200mm zoom range works for both intimate and expansive views. And don’t forget your macro lens for ultimate detail on these miniature creatures.
Post processing lets you optimize color, contrast, and composition. Slight brightening brings out the vivid orange hues against dark wings. Careful cropping hones the focus to patterns, shapes and textures within the frame. Don’t forget to back up those butterfly beauties since film cards fill fast when shooting bursts.
Flutter By: Chasing Monarchs on a California Road Trip - Citizen Science Opportunities
Monarch mania inspires many enthusiasts to look beyond passive appreciation and become actively involved in conservation. Citizen science projects allow people of all ages and backgrounds to contribute to the study and protection of these captivating creatures. And opportunities abound for both field work and virtual research.
Hands-on initiatives like the Monarch Larva Monitoring Project rely on volunteers to track caterpillars and milkweed habitat. Participants keep an eagle eye out while exploring parks and nature preserves. When they spot a caterpillar munching away, they record critical data like its stage of development and milkweed species. This helps scientists assess how breeding success correlates with location and diet. Folks eager to get even more hands-on can raise caterpillars themselves and tag the emerging butterflies.
Tech-savvy initiatives, like Journey North, cater to virtual volunteers. This online platform collects monarch sightings and also invites people to track spring migration. Using the app lets you directly upload pictures and location information to contribute. This real-time data creates a detailed map that scientists analyze for migration timing and population trends. They can quickly identify potential threats and respond to protect monarchs on the move.
For data-driven researchers, Project Monarch Health enlists help assessing population health. Volunteers collect and test monarch specimens for infection with the debilitating Ophryocystis elektroscirrha (OE) parasite. This sometimes deadly disease makes the arduous migration impossible for infected monarchs. So tracking OE prevalence and distribution is crucial for safeguarding the butterfly’s future. The project ships sampling kits that allow people to easily submit specimens by mail.
Hands-free computer tasks also advance understanding of the monarch's plight. Data entry on platforms like Zooniverse lets citizen scientists convert raw research into usable formats. Projects might involve identifying and labeling butterfly features or counting individuals within photos. Pattern recognition and image processing algorithms rely on this human-generated data to become more accurate.
Flutter By: Chasing Monarchs on a California Road Trip - Threats Along the Route
The monarch's extraordinary migratory journey faces escalating threats that jeopardize this natural wonder. Habitat loss across their range in the U.S. and Canada takes an extreme toll on breeding, migrating, and overwintering populations. Pesticides and herbicides reduce milkweed and nectar sources while directly poisoning adults and larvae. Climate change disrupts delicate timing and conditions the migration relies on. And car strikes take a deadly toll when monarchs traverse highways on the move.
One of the biggest challenges is the shrinking supply of milkweed that caterpillars depend on. Agricultural practices eliminate wildflowers from farmland where monarchs once thrived. Urban and suburban development pave over breeding habitat. Declines up to 90% in the monarch's eastern population get attributed to milkweed eradication. Out west, over 60% of overwintering sites have been lost to human activities. Groves sheltering western monarchs lack strong legal protections. Key sites succumb to development pressures or inappropriate tree management.
Climate change also threatens to derail the monarch’s time-honored migration. Warming fall temperatures may spur premature departure from northern latitudes. Southerly sites could become too hot and dry if conditions don’t sync with later arrival. Critical timing mismatches could leave monarchs stranded without milkweed or winter shelter. Extreme weather like droughts, storms, and wildfires also endanger migrating and overwintering monarchs.
Vehicles take a shockingly heavy toll when migrations cross highways. Researchers estimate car strikes could kill up to 108 million monarchs every year in the U.S. alone. This frightening figure underscores the need for safer roadways like wildlife bridges and underpasses. It also shows why citizen scientists must get involved tracking road mortalities. Targeted rescues help too. In California, a Butterfly Highway Patrol documents hotspots to address and rushes winged accident victims to a butterfly trauma center for care.
Though daunting, the threats monarchs face inspire action rather than apathy. Media coverage showcases conservation success stories that offer hope, not doom. And individuals feel empowered to make an immediate difference in their own communities. People plant milkweed corridors along sidewalks, in schoolyards, and across their yards to facilitate migration. Gardeners reduce pesticide usage and increase flowering plants. Teachers introduce students to monarch life cycles up close and spark curiosity. Tourists trade trampling for treading lightly in overwintering groves. And ordinary folks help scientists track monarch populations year after year.
