Butterflies: Their Natural History and Diversity

 


 Butterfly lovers will be enchanted by this coffee table book by Ronald Orenstein and Thomas Marent (photographer). The exquisite photography showcases the images of butterflies from all over the world along with interesting facts about them.

 The symbolism of butterflies is as rich as the imagination of passionate artists. Different cultures attach various meanings to them. In Japan and Mexico, for example, butterfly life cycles represent birth, death and rebirth. Mexicans associate the arrival of Monarch butterflies on their wintering grounds with the souls of their ancestors; it coincides with the Day of the Dead.

 Different Native American cultures view butterflies as symbols of transformation, change, comfort and hope.

 Butterflies captivate the interest of scientists, artists and engineers. The study of these mesmerizing insects relates to aspects of technology and design. Butterflies offers several amazing facts about these intriguing creatures.

 You will probably be surprised to learn that Monarchs are not the only migratory butterflies. For example, whites, sulphurs and swallowtails are accomplished long-distance migrants.  

 Another remarkable example are the Painted Ladies (Vanessa cardui). Their route is much longer than that of the Monarchs. It involves a round trip from tropical Africa to the Arctic; as they cross the Mediterranean they are propelled by the tailwinds from North Africa.

  Adult Painted butterflies live only for a few weeks, so it takes six generations to complete the migratory cycle.

 Tropical butterflies migrate too. Butterflies from the forests of the northwest of Costa Rica migrate during the dry season toward humid areas.

 You may already be familiar with the migration of Monarch butterflies.

 


 Northern Monarch butterflies fly southward to their wintering grounds in central Mexico, although a few of them stay in Florida and Cuba. The following spring they migrate north again, but only one-tenth of them live long enough to return to the north. Most lay their eggs on southern milkweeds and die. Their offspring  head north in less than a month.

 Monarchs do not tolerate freezing temperatures, so they are well adapted to migration. Their wings are equipped for this purpose, and they have a structure in the brain that reacts to the position of the sun and the patterns of polarized light in the sky. There is also a so-called clock in the antenna that detects the sun’s position changes. The combined information from the clock and the compass in the brain keeps the butterflies on track toward their destination. Painted ladies, however, lack the antennal clock.

The variety of colorful butterflies and the incredible facts included in the book make the read fantastic; it sparks a sense of wonder to get to know butterflies in places we may never get to visit.


Meet the Panacea prola in Ecuador. They land on animals - humans included - to drink their sweat. They also drink from puddles, rotting wood or wet leaves.






The dazzling Dryas iulia can be found in the southern United States, Central America, the Caribbean and parts of South America (Brazil and Peru, for example). Males spend much of the day searching for females. They sip liquid and minerals from the eye secretions of caimans in Brazil and from the eyes of turtles in Peru. I had to find a photo to believe it.

 For Monarch butterflies the presence of milkweed is essential for the survival of their caterpillars. Without milkweed, Monarch butterflies will go extinct.

 


 In the American Midwest, vast fields of genetically modified herbicide - and - pesticide resistant- crops (corn, soybean and cotton) are sprayed with chemicals that destroy milkweed and kill off butterflies.

  Butterflies are disappearing in many parts of the world due to chemical pollution, habitat destruction and climate change.

The more we learn, the more we can support their survival.

Avoid spraying herbicides and pesticides in your yard; let wildflowers thrive. Plant milkweed to support Monarch butterflies

 There are various Citizen science projects in North America that study and protect butterflies: The Monarch Watch, The Western Monarch Count, The Vanessa Migration Project, and the Los Angeles Butterfly Survey are some examples.

  In Britain you can search for the United Kingdom Butterfly Monitoring Scheme and the New Millenium Project. Do your research where you live and learn what is going on there. You may come across opportunities to cooperate with projects.


 Find out what wildflowers in your area are beneficial to butterflies and plant something to support them. Whether you have a garden, a patio, a balcony or just a window sill, planting something can brighten up your space, support your mental health and attract butterflies.

Butterflies was published by Firefly Books.

Bicycling with Butterflies has a special place in my heart because it is the book that inspired me to come back to write book reviews.

Enjoy My Writing Life ride, and go plant some flowers.
