Summary of Butterflies: Featuring Monarchs – Connecticut’s Beardsley Zoo:
The content written by Aimee Turcotte, a Zoo Educator, focuses on butterflies, highlighting their unique characteristics such as size, shape, color, and their role in pollination. It discusses how caterpillars feed on specific plants like dill and milkweed before transforming into butterflies that rely on nectar for sustenance. Butterflies contribute to plant reproduction and biodiversity but are less efficient pollinators than bees and hummingbirds. The blog emphasizes butterflies’ role as ecosystem health indicators.
Turcotte is particularly interested in Monarch butterflies, detailing their physical characteristics, toxic defense mechanisms, and mimicry by other species. Monarch butterflies are endangered, facing threats from climate change, habitat destruction, and pesticide use. The decline in their population and habitat in Central Mexico is noted, with the number of occupied forest acres significantly reducing over decades.
Conservation efforts are highlighted, including programs such as MonarchWatch at Connecticut’s Beardsley Zoo, which tags Monarchs to track their migration. The zoo also offers educational activities like a scavenger hunt in June to raise awareness about monarch butterflies. The blog concludes by inviting readers to participate in these conservation activities and learn more about Monarch butterflies.

Butterflies are among the most colorful and fascinating insects. There are many species, each distinguished by unique traits such as size, shape, color, and pattern. Caterpillars, the larval stage of butterflies, depend on plants like dill, passionflower, chokecherry, and milkweed for nourishment. This early diet is crucial as these larvae transform into butterflies, primarily feeding on nectar, a sugary fluid from flowering plants.
During the process of feeding on nectar, butterflies inadvertently contribute to pollination. Pollen adheres to their bodies as they travel from one flower to another and is transferred. Though they are not as efficient as bees, butterflies still play a vital part in pollination. Compared to bees, butterflies have specific limitations; their long, thin legs prevent them from getting as close to the pollen, and they lack the acute sense of smell that bees possess. However, butterflies can see the color red, making them adept at locating brightly colored flowers that bloom during daylight.
One exemplary species of butterflies is the Monarch. Monarch butterflies are lightweight, tipping the scales at just 0.0095 to 0.026 ounces, with wingspans ranging from 3.7 to 4.1 inches. Their vivid orange wings accentuated with black veins and white spots, are not merely for show but serve as a warning sign to predators about their toxicity. This toxicity results from their diet, which includes milkweed, making them poisonous to many predators. Interestingly, other butterfly species like Viceroy, Queen, and Soldier butterflies mimic Monarchs to deceive predators into thinking they are also toxic.
Despite their resilience, Monarch butterflies face significant threats, primarily from human activities impacting their habitat and migration routes. Each fall, monarchs embark on an arduous journey, migrating from the United States and Canada to Southern California and Mexico, covering distances up to 3,000 miles. Climate change exacerbates their dangers; the increased frequency and intensity of hurricanes, driven by warmer ocean temperatures, adversely affect their migration.
Human-induced habitat loss further compounds the issue. Deforestation, prevalent pesticide use in gardens, and a decline in native plant species have steadily diminished the ecosystems that Monarch butterflies rely upon. Since the 1990s, there has been a steady decline in their populations, especially noticeable in Central Mexico. Monarchs occupied around 45 acres of forest in 1996-1997, but this number had reduced to approximately 2.2 acres by 2023-2024, according to recent reports by the World Wildlife Fund.
Fortunately, numerous conservation initiatives are dedicated to reversing this decline. Connecticut’s Beardsley Zoo, for instance, is actively involved in butterfly conservation through programs like MonarchWatch. This citizen science initiative encourages volunteers to tag Monarch butterflies, aiding researchers in tracking their migration and gathering data crucial for understanding population trends.
As part of their efforts, the zoo also conducts the Cool Blue Bridgeport program in June, a series of educational activities focusing on Monarch butterflies. Visitors can participate in scavenger hunts designed to educate and engage, with the added incentive of winning a water bottle upon completion.
By fostering awareness and participation through such programs, Connecticut’s Beardsley Zoo aims to instill a sense of responsibility and enthusiasm for butterfly conservation among the public. While Monarch butterflies face numerous challenges, ongoing conservation efforts offer hope for their future. By supporting programs like MonarchWatch and participating in local conservation activities, individuals can contribute significantly to preserving these remarkable creatures.
