Kaksisiipisten

Kaksisiipisten is the Finnish word for the insect order Diptera. This order encompasses a vast array of insects commonly known as flies. Diptera are characterized by having only one pair of functional wings, with the hindwings reduced to small, club-like structures called halteres. These halteres are used for balance during flight.

The order Diptera is incredibly diverse, with tens of thousands of described species found worldwide. They occupy a wide range of ecological niches, from decomposers and pollinators to predators and parasites. Their life cycles typically involve complete metamorphosis, with egg, larval, pupal, and adult stages. The larval stage, often referred to as a maggot, is usually found in moist environments like soil, decaying organic matter, or aquatic habitats.

Flies play significant roles in ecosystems. Some, like mosquitoes, are vectors for diseases, while others, such as hoverflies, are important pollinators. Many species are scavengers, aiding in the decomposition of dead organisms and waste. The ecological and economic impact of Diptera is considerable, making them a crucial group of insects to study.
