sukkiaisia

Sukkiaisia is a Finnish term that translates to "long-legged flies" or "stilt-legged flies" and refers to the family Dolichopodidae. These are small to medium-sized predatory flies, typically found in moist habitats such as near streams, ponds, and wetlands. They are characterized by their long, slender legs, which they use to walk on water surfaces or to quickly move among vegetation.

Dolichopodidae are an extremely diverse family, with thousands of described species worldwide. Their coloration can vary significantly, often exhibiting metallic green, bronze, or blue iridescence, which can be quite striking. Both males and females are predatory, feeding on small invertebrates like springtails, mites, and other small insects, which they often capture while walking or flying.

Many species of Sukkiaisia are known for their elaborate courtship rituals. Males often perform intricate aerial dances or present gifts, such as prey items or specially constructed silk structures, to entice females. The larvae of these flies are also predatory and typically inhabit damp soil, decaying wood, or aquatic environments. Due to their predatory nature and association with clean water sources, some dolichopodid species are considered indicators of healthy ecosystems.
