6 Reasons Why Butterflies are Important for the Planet

Butterflies are a common sight in meadows, forests, and gardens across the world. They are integral to ecosystems and have big effects on their environment.

What are Butterflies?

Butterflies are flying insects with scaled wings. They are often covered in intricate patterns and bright colors.

There are over 20,000 species of butterfly with most living in tropical rainforests.

Butterflies go through metamorphosis, which means their appearance changes after they hatch from an egg. They often begin life within an egg laid on a leaf.

The butterfly’s next stage is as a larva or caterpillar, where they eat large amounts to grow as big as possible. It is then time to transform as they change into a chrysalis, where they stay suspended within a cocoon.

The butterfly’s cells become liquid within this chrysalis before forming again. Once complete, they exit the cocoon as a butterfly, ready to mate, and begin the cycle again.

Top 6 Reasons Why Butterflies are Important?

1. Butterflies are valuable pollinators

These pretty insects have an important role in the pollination of plants.

Butterflies feed on nectar deep within flowers and rub up against pollen. This contains genetic material which attaches to the butterfly and is deposited in other flowers they visit.

The pollen ends up in the female part of another flower of this plant, allowing for reproduction.

We can thank pollinators like butterflies for food like the fruits and vegetables we eat. They are responsible for one in every three bites of food we consume and contribute over 200 billion dollars to the food economy worldwide.

Butterflies are important pollinators as they travel long distances.

The pollen attached to their bodies and legs is spread further than that of a honey bee which stays close to the hive. This is beneficial to plants and the planet as it promotes genetic variation and resistance to diseases.

2. Butterflies show the health of an ecosystem

Ecosystems rely on every animal, insect, and plant to maintain balance and thrive. Research into the size of butterfly populations shows whether the ecosystem is stable.

Butterflies, in their various life stages, provide food for many animals like birds, small mammals, and other insects.

Certain species of butterflies eat aphids which help to control these pests. They provide an important service by controlling populations of other animals and insects.

Butterflies are usually found in large numbers at specific times of the year. This makes them an important part of the food chain for many species.

Butterflies are integral to many ecosystems as food for other creatures and pollinators for plants.

3. Studying butterflies lead to important scientific research

Butterflies are unique in the insect world because of their intricate life cycle and impact on the natural world. This has resulted in butterflies being the focus of studies and in-depth research.

Monarch butterflies choose specific plants, like milkweed, as food for their larvae. They lay eggs on toxic leaves ready for the caterpillars to emerge and eat. This reduces parasites in larvae and caterpillars and stops predators from eating them. This leads to more caterpillars surviving and becoming butterflies, increasing the population.

This discovery into butterfly behavior shows how plants might be useful for medicine. Scientists are investigating how plants with anti-parasitic properties like milkweed could benefit people. Butterflies’ research might one day lead to an important medicinal discovery.

4. Butterflies offer educational benefits

Alongside the honeybee, butterflies are one of the key insects that are taught in school. The metamorphosis from a larva into a butterfly is a great way to share the magic within nature.

This helps to engage children in science and biology and could lead to careers in these fields. There is a need to diversify careers in the Science, Technology, Engineering, and math (STEM) fields.

Black and Hispanic groups make up only 17% of those in STEM. Encouraging interest early in education could help to increase these figures.

5. Butterflies are an indicator of the effects of climate change

Butterflies are sensitive to changes in the environment and have been a focus of studies. They rely on specific conditions and environmental cues to complete their delicate life cycle.

When there are changes to their environmental conditions, there is a decline in population numbers.

Butterflies are an excellent subject for research when looking at the impact of climate change on many ecosystems. Butterflies can often be the first indicator that the ecosystems are facing issues.

Scientists are also studying species of butterfly that have been able to adapt to changes in the climate, which brings hope for the future.

6. Butterflies promote tourism

Butterflies have been admired for hundreds of years with specimens displayed in museums. In the last five years, butterfly tourism has increased in popularity as people from around the world enjoy the beauty of these insects. This intrigue is not just for scientific purposes, but also to experience the joy of butterflies in their natural habitat.

In Texas, there is an annual butterfly festival where you can see over 400 species of butterfly. This contributes to the local economy, with tickets costing hundreds of dollars.

Butterfly tourism is simple to arrange, as they are found in large numbers and do not need much infrastructure. Butterflies are important within wildlife tourism and contribute to local economies worldwide.

What Challenges do Butterflies Face?

Butterflies have been declining in numbers for over 50 years. Worldwide, there has been a 2% drop in populations and in Europe, 30% of all butterfly species are in decline, with 10% likely to become extinct.

Climate Change

Climate change has led to temperatures changing in unpredictable ways. Butterflies rely on environmental cues to know when to emerge from the egg.

If this happens earlier than usual, then the food sources they rely on could be unavailable or it may be too cold for them to survive.

Severe Weather

Severe weather can hurt butterflies as temperature changes, wind and rainfall can destroy their eggs and habitat.

Habitat Loss and Deforestation

Habitat loss and deforestation are also affecting butterflies. Many species of butterfly have adapted to their environment, meaning they rely on certain plants for food or for laying their eggs. If this habitat is destroyed, the population can quickly decline.

Pesticides and Insecticides

Pesticides and insecticides are also damaging butterfly populations.

The chemicals kill plants that the butterflies rely on and pesticides containing neonicotinoids harm the butterfly. These chemicals can linger in the soil where they enter the water cycle, posing a threat to butterflies everywhere.

Urbanization

Butterflies are heavily affected by urbanization. There are many species of butterfly that migrate long distances but cannot complete the journey because of the introduction of new buildings and walls. This has led to populations declining, as they cannot reach the area where they reproduce.

There may be many species of butterfly that become extinct in the next few years because of these physical barriers.

What Can You Do to Help Butterflies?

There are things you can do to help these important insects. It is vital that butterfly populations are stabilized by protecting existing habitats and increasing access to new areas.

We should also focus on funding further research into insects and sharing this information with the public.

1. Make Outdoor Spaces Insect-friendly

One way of helping local butterflies is to make outdoor spaces insect-friendly. Plant native flowers like Buddleia, Phlox, or Marigolds that butterflies can feed on.

It is also important to have areas of shade with water for butterflies to rest.

Butterflies can also feed on fallen fruit, so it is important to leave this on the ground.

2. Support Charities

Supporting charities that are working to protect butterflies and their habitats is another good way to help these insects.

Save Our Monarchs is dedicated to saving the iconic Monarch butterfly, which has declined 90% in the last 20 years in North America.

Xerces Society for Invertebrate Conservation is a worldwide charity that protects all invertebrates, including butterflies.

3. Reduce Your Impact

Reducing your impact on the environment will also help butterflies. They are sensitive to changes in climate, therefore you can help by adjusting your lifestyle to limit the effects of global warming.

Switch to renewable energy sources to reduce your carbon footprint, or make eating more plant-based foods.

4. Advocate for the Protection

Advocate for the protection of insects by bringing this to the attention of your government. Insects, including butterflies, are often overlooked when it comes to environmental protection.

The plight of mammals like the polar bear is more enticing than small creatures like insects.

Encouraging governments to place protections on butterflies and insects will help many ecosystems.

Specifically, this could be done by banning the use of pesticides that harm butterflies and other creatures.
