kaksisiipiset

Kaksisiipiset is the Finnish term for the insect order Diptera. This order is characterized by having only one pair of functional wings, with the hind wings reduced to small, club-shaped structures called halteres. These halteres are believed to aid in balance during flight. Diptera is a highly diverse and widespread group, encompassing a vast array of species found in nearly every terrestrial and freshwater environment.

Common examples of kaksisiipiset include flies, mosquitoes, gnats, midges, and crane flies. Their mouthparts vary greatly depending on their feeding habits, ranging from piercing-sucking in mosquitoes to sponging in houseflies. The life cycle of kaksisiipiset typically involves complete metamorphosis, with four distinct stages: egg, larva (often called a maggot), pupa, and adult.

Many species of kaksisiipiset play important ecological roles. Some are vital pollinators, while others are crucial decomposers, breaking down organic matter. However, some species are known as pests, affecting agriculture, and others are vectors for diseases that impact human and animal health. The study of kaksisiipiset is known as dipterology.
