Did you know that scientists are always finding new kinds of insects? There are already about 160,000 different types of butterflies and moths in museums around the world. Every year, around 800 new species are discovered! Flies are another fascinating group of insects. We know about nearly 160,000 different kinds of flies, but that’s not the whole story. In just one year, 30 new fly species were found in Los Angeles alone! There might even be more flies than beetles, but since flies aren’t as popular, fewer people are looking for them. That’s a shame because flies are quite beautiful when you take a closer look.
Flies are like tiny machines with incredible features. They have special parts called halteres, which are like gyroscopes. These are their hind wings that have evolved into long stalks with a heavy club at the end. As flies fly, these halteres move up and down. At the base of the halteres, there are tiny sensors that measure how the stalks bend and twist. This information is sent to the fly’s brain, helping it control its flight. This allows the fly to adjust its flight path with precision, even when the wind or other factors try to throw it off course.
Flies also have interesting mouthparts designed for feeding on liquids. Imagine a sponge on a stick—that’s how a fly’s mouth works! While insects sometimes get a bad reputation, especially those that live near humans, we can appreciate how they make the most of their surroundings. For example, bean weevils can live their entire lives inside a single bean, growing from egg to adult. Beetles are another type of insect that can thrive in many environments, from our homes to distant rainforests. Some beetles even eat a variety of foods, from grains to unexpected things like pasta and mouse droppings.
Insects are incredibly adaptable creatures. They can live in many different environments, including our homes, thanks to their flexible body design. One key feature that helps them survive is their hard outer skeleton, known as an exoskeleton. This exoskeleton provides protection and support, allowing insects to thrive in various conditions.
Flies and other insects are more than just pests; they are fascinating creatures with amazing adaptations. By understanding their unique features, we can appreciate the incredible diversity of life that exists right under our noses.
Start your own insect discovery journal! Spend a week observing different insects in your backyard or local park. Draw sketches of the insects you find and note down their unique features. Try to identify them using an insect guidebook or online resources. Share your findings with the class and discuss the diversity of insects you discovered.
Create a 3D model of a fly using craft materials. Focus on replicating the fly’s unique features such as the halteres and mouthparts. Use materials like clay, pipe cleaners, and paper to construct your model. Present your model to the class and explain how these features help flies survive in their environment.
Conduct a simple experiment to understand how halteres work. Use a small fan to create wind and try to keep a paper airplane steady in the air. Discuss how the fly’s halteres help it maintain balance and control its flight path, even in windy conditions. Reflect on the engineering marvels found in nature.
Participate in a role-play activity where you act as different insects adapting to various environments. Consider how your insect’s body structure and features help it survive. Share your adaptation strategies with the class and discuss the importance of adaptability in the insect world.
Create a diorama showcasing a specific insect’s habitat. Include elements that represent the insect’s environment and the resources it needs to survive. Explain how the insect’s adaptations make it well-suited for this habitat. Display your diorama in the classroom and explore the diverse habitats insects can thrive in.

Museums around the world already house 160,000 different butterflies and moths, but every year we discover about 800 new species. Flies are another group of insects; there are nearly 160,000 different kinds that we already know about, but that’s just part of the story. Recently, in just one year, 30 new species were discovered within the city of Los Angeles alone. It might be that there are even more flies than beetles, but they are not as popular, so fewer people are searching for new ones. This is unfortunate because they are just as beautiful when observed closely.
Flies are remarkable examples of microengineering, equipped with advanced features. They have gyroscopic stabilizers, and their hind wings are reduced to long stalks with a heavy club at the tip called halteres. These halteres beat up and down as they fly. At their base, there is a complex arrangement of tiny sensors that measure stresses along the stalk. These little knobs behave like gyroscopes, always beating in the same direction as the fly’s body turns. The halteres bend and twist at their base, and the sensors send this information to the fly’s brain, providing continuous feedback on its flight attitude, including roll, pitch, and yaw. This gives the fly precise control of its flight path, regardless of external factors.
Their mouthparts are also beautifully engineered, designed like a sponge on a stick for liquid feeding. Insects often receive negative attention, especially those that interact with humans. However, we can admire how they take advantage of opportunities that often go unnoticed. For example, many generations of bean weevils live out their lives in a jar of dried beans, growing from egg to adult inside a single bean. Beetles thrive in both our world and remote rainforests, with species that consume various types of grains, including flower beetles and rice weevils. Some beetles are even known to eat a wide range of materials, from pasta to mouse droppings.
Insects have successfully adapted to various environments, including ours, due to their flexible body design, which is largely attributed to a key feature shared by all insects: their hard outer skeleton, known as an exoskeleton.
