The collective imagination of humankind envisions animals to be big and in most cases to be mammals. However, insects, in fact, make up a population of about 10 quintillion. So, it's worth understanding more about the different species in this class of animals.

In this article, we will learn about the intriguing creature that is the Crane fly. Crane fly is the common name that has been given to insects that belong to the family Tipulidae. The crane flies are often referred to as 'Daddy long legs' or 'mosquito hawk'. While they resemble mosquitoes, they are not as harmful in any meaningful way. There are about 15,000 crane fly species. As crane fly larvae, they are voracious eaters as they feed on decaying wood and vegetation like algae and microflora. Surviving only for days as adult crane flies, its purpose is to seemingly mate before dying. While they are harmless to humans directly, they can be pests to crops. Thus, pest management is an important service when their population is out of control. Having been around at least since the Barremian stage and being found in every part of the world from tropics to temperate regions, it is a shame that we know very little of these creatures. Read on to learn more Crane fly facts for kids and even a few phantom crane fly facts.

When the eggs hatch, the crane fly larvae that emerge from the eggs have a slug-like look with a tough outer skin which gives them the nickname 'leatherjackets'.

Crane fly are called 'daddy long legs' because of their extremely long and thin legs.

In some parts of the world, Crane flies are considered to be pests. An example of this is the United States, where they have become invasive. Although they do not bite humans and cannot transmit any disease, unlike mosquitoes, they are pests to turf, field crops, and pasture grass. Thus, the answer to whether you should kill a crane fly depends on whether it's causing harm. In isolation, they are harmless and do not need to be killed.

Did you know...

The Crane fly larvae can actually serve as an important element in the upkeep of the soil ecosystem. The larvae do so by increasing the organic content of the soil and in general increasing the microbial activities in the soil. They also serve as part of the larger ecosystem where they serve as reliable prey to animals like spiders, fish, frogs, and birds.

Crane Fly bites

A Crane fly bite is almost a misnomer as these insects, although look like big mosquitoes, do not actually bite. There is in fact a myth that their venom is the deadliest in the world, which does not make sense as the insect does not even bite to begin with, let alone bite with venom (which also is obviously not there).

Crane Fly vs. mosquito

Mosquitos measure at just 0.3-0.5 in (0.7-1.3 cm) compared to 1-1.5 in (2.5-3.8 cm) long like the crane fly. Crane flies have a V-shaped body that is paired with long slender legs which makes them unstable fliers in contrast to the agile mosquito. As opposed to the mosquito, Crane flies do not spread any disease and are, in general, harmless to humans. Crane flies are incorrectly labeled as 'mosquito eaters' or 'mosquito hawks' as they do not hunt or eat mosquitos. In fact, as adult Crane flies, they don't eat anything at all.
