Kransvener

Kransvener, also known as the *crane fly* in English, is a common name for several species of large, delicate-looking insects belonging to the family Tipulidae. These insects are often mistaken for small mosquitoes due to their long legs and slender bodies, but they are harmless and play an important ecological role.

Adult crane flies are typically winged and exhibit a slender, elongated body with long, thin legs. Their wings are often transparent or lightly veined, and their antennae are long and segmented. While they lack the proboscis of true mosquitoes, their appearance can be alarming to some people. Crane flies are generally found near water sources, such as ponds, marshes, and streams, where their larvae develop.

The larvae of crane flies, known as leatherjackets, are aquatic or semi-aquatic and feed on organic matter, including decaying plant material and small invertebrates. They play a role in nutrient cycling by breaking down organic debris in their environment. Some species, however, can be pests in lawns and gardens, as their larvae may feed on grass roots, leading to patches of dead or dying turf.

Kransvener adults do not feed on blood or plant sap; instead, they primarily consume nectar and other plant fluids. Their short adult lifespan, often just a few days, is spent mating and laying eggs. Females deposit eggs in moist soil or near water, ensuring the continuation of the life cycle.

While crane flies are not considered harmful to humans or plants, their abundance can sometimes be a nuisance. They are most active during warm, humid weather and are commonly observed in late summer and early autumn. Efforts to reduce their presence in lawns often focus on improving drainage and maintaining healthy soil conditions to discourage larval activity.
