The Incredible Insects of Hawaii

Hawaii is known for its tropical climate, beautiful beaches, and vibrant culture, but it is also home to a variety of insects. These include both native and introduced species that have adapted to the unique environment of the Hawaiian Islands. In this article, we will explore some of the common insects found in Hawaii and their characteristics.

The Insect Diversity in Hawaii

One of the most interesting aspects of Hawaii is its unique and diverse ecosystem. The islands are home to a wide range of plants and animals, including a fascinating array of insects. Hawaii has over 6,000 species of insects, a staggering number for such a small landmass. In fact, Hawaii has more insect species per square mile than any other place on Earth.

The Native Insects of Hawaii

Of the 6,000 species of insects in Hawaii, over half of them are native to the islands. These insects have evolved over millions of years to survive in the unique environment of Hawaii. Some of the native insects of Hawaii include the Kamehameha butterfly, the Oahu tree snail, and the Kauai cave wolf spider.

The Invasive Insects of Hawaii

Unfortunately, Hawaii’s delicate ecosystem has been disrupted by the introduction of non-native species. Invasive insects, brought to the islands by humans, have wreaked havoc on Hawaii’s native flora and fauna. Some of the most destructive invasive insects in Hawaii include the coqui frog, the Argentine ant, and the little fire ant.

The Most Fascinating Insects in Hawaii

Hawaii’s insect population is incredibly diverse, with many fascinating species. Here are some of the most interesting insects found in Hawaii:

Key takeaway: Insects play a vital role in Hawaii’s delicate ecosystem as pollinators, decomposers, and food sources for other animals. However, they are facing threats such as habitat loss, climate change, and invasive species, which could lead to a decline in insect populations and a loss of biodiversity.

The Kamehameha Butterfly

The Kamehameha butterfly, also known as the Pulelehua, is a beautiful butterfly found only in Hawaii. It is named after King Kamehameha I, who united the Hawaiian Islands. The butterfly is bright orange with black markings and is often seen fluttering around flowers.

The Hawaiian Happy Face Spider

The Hawaiian happy face spider is a small spider with a unique pattern on its abdomen that resembles a smiling face. It is found only in Hawaii and is quite rare. The spider is harmless to humans and feeds on insects.

The Hawaiian Sphinx Moth

The Hawaiian sphinx moth is a large moth with a wingspan of up to 5 inches. It is known for its long proboscis, which it uses to extract nectar from flowers. The moth is an important pollinator and is found throughout Hawaii.

The Importance of Insects in Hawaii

Insects play an important role in Hawaii’s ecosystem. They are pollinators, decomposers, and prey for other animals. Without insects, Hawaii’s delicate ecosystem would be thrown off balance, affecting everything from the plants to the animals.

Key Takeaway: Insects play an important role in Hawaii’s ecosystem as pollinators, decomposers, and a food source for other animals. However, they are facing threats such as habitat loss, climate change, and invasive species, which can disrupt the delicate balance of the ecosystem.


Many of Hawaii’s plants rely on insects for pollination. Bees, moths, and butterflies are just a few of the insects that help to pollinate Hawaii’s flowers. Without these insects, many of Hawaii’s plants would not be able to reproduce.


Insects also play an important role in decomposing organic matter. They break down dead plants and animals, returning nutrients to the soil. This process is essential for maintaining healthy soil and promoting plant growth.

Food Source

Insects are an important food source for many animals in Hawaii. Birds, lizards, and other animals rely on insects for their survival. Without insects, these animals would have a difficult time finding food.

The Threats Facing Hawaii’s Insects

Despite the important role that insects play in Hawaii’s ecosystem, they are facing a number of threats. Habitat loss, climate change, and the introduction of invasive species are just a few of the factors affecting Hawaii’s insects.

Habitat Loss

As more and more land is developed in Hawaii, insects are losing their habitats. This can lead to a decline in insect populations and a loss of biodiversity.

Climate Change

Climate change is also affecting Hawaii’s insects. As temperatures rise, some insects may not be able to survive in their current habitats. This could lead to a decline in insect populations and a loss of biodiversity.

Invasive Species

Invasive species, such as the little fire ant and the coqui frog, are a major threat to Hawaii’s insects. These species can outcompete native insects for resources and disrupt the delicate balance of Hawaii’s ecosystem.

FAQs – What Insects are in Hawaii

What are some common insects found in Hawaii?

Hawaii is home to various insect species, but some of the most common include mosquitoes, ants, roaches, centipedes, and termites. Mosquitoes can be found on all islands and are active throughout the year, while ants can be found in many different habitats such as forests, grasslands, and urban areas. Meanwhile, roaches can be found in dark and damp places like basements and sewers, while centipedes are common in rainforests and other damp areas. Termites are also prevalent, especially in residential areas throughout the state.

Are there any dangerous insects in Hawaii?

While most of the insects in Hawaii are harmless, there are some that can pose a danger to humans. For instance, centipedes have a painful bite that can cause swelling and discomfort. Some species of ants, like the little fire ant, can also cause painful stings. In rare cases, mosquitoes in Hawaii can carry diseases like dengue fever or the Zika virus. However, with proper precautions, such as using insect repellent, the risk of insect-related injuries can be minimized.

Can insects in Hawaii impact the environment?

Insects can have a significant impact on the environment, both positive and negative. For example, honeybees and other pollinators play a critical role in maintaining the ecological balance and supporting Hawaii’s agriculture industry. However, invasive insect species, such as the coffee berry borer, have caused millions of dollars in damage to coffee crops. Additionally, some insects, like the coqui frog, can be detrimental to the natural habitat of Hawaii and its native species.

What steps are being taken to control insect populations in Hawaii?

The Hawaii Department of Agriculture takes several measures to control invasive insect populations on the islands. These include quarantine regulations, Monitoring and surveillance programs, and biological control measures. Quarantine regulations are in place to prevent the spread of invasive species into Hawaii. Monitoring and surveillance programs help to detect new pest arrivals as soon as possible so they can be assessed and managed effectively. Biological control measures involve the use of natural predators or other environmentally-friendly methods to control invasive insect populations.

Can tourists bring insects into Hawaii?

Hawaii has strict regulations in place to prevent the introduction of new insect species to the islands. Tourists are prohibited from bringing certain items, such as plants or animals, into Hawaii that can carry invasive species, including insects. Visitors should always check with the Hawaii Department of Agriculture before bringing any items to Hawaii to ensure they are not violating any regulations. Accidentally introducing an invasive species can have major consequences for the ecosystem, agriculture, and the economy of Hawaii.
