When it comes to the food they eat, there is a much bigger difference between the two. As mosquitoes often feed on animal and human blood, crane flies do not. Crane flies are also called mosquito hawks, which somehow do not help in detaching them from the stereotype that crane flies are just another species of mosquitoes. And contrary to popular belief, crane flies do not eat mosquitoes. So, what do crane flies eat?
What Do Crane Flies Eat?
During their adult stage, crane flies seldom eat as they are primarily focused on mating and laying down eggs. But when the rare need arises, adult crane flies eat nectar and pollen from flowers and other outdoor plants. Crane fly larvae, on the other hand, eat roots of grass, decaying wood, seedlings, fungi, algae, and other vegetation. Adult crane flies live only for a very short period of time. They go through a few stages in their life cycle until they finally reach adulthood that usually lasts for only 10 to 15 days. Only their larval stage eats, and as they reach adulthood, they often use most of their time searching for a partner to mate with and laying eggs before their time is up. Adult crane flies are rarely seen feeding, but whenever they feed, they often eat nectar and pollen. Yet, crane flies do not really need to feed on anything during their adult stage. In fact, they become completely harmless during this stage as they do not have mouth parts that can help them suck blood like mosquitoes or eat and destroy crops and vegetation like their larval counterparts.
What Do Crane Fly Larvae Eat?
Unlike adults, crane fly larvae are voracious eaters. These larvae, also called leatherjackets, feed on decaying wood, roots of grass and flowers, decaying organic matter and plant life, fungi, and other vegetation. Crane fly larvae are often a problem to many farmers all over the world. In fact, of their four life stages, the larval stage poses the most threat to farmers and their plantation. They can be harmful for gardens, yards, and other plantation and vegetation areas as they often eat roots and stems just below the ground’s surface, damaging many plantations and flowers. The crane fly larva eats the roots of vegetation and other plants, and it does this till it reaches adulthood. As the larva grows, it does not run out of food as adult crane flies deposit their larvae in soil that is moist and surrounded by healthy vegetation. Given this, the larval stage is the most important part of the crane fly life cycle as a larva’s main role is to feed on plant matter in order to help it grow.
Are Crane Flies Harmful to Humans?
Crane flies, in contrast to mosquitoes, are not dangerous to humans. They are, however, quite harmful for plants and vegetation. Their larval stage can damage grass and other vegetation to a great extent, which may cause the need for the removal of the affected plant. Crane flies often don’t bite or sting people but can be a big problem for grasses, pastures, golf courses, and crops. Their ravenous larvae are to blame for this, since they can turn grasses yellow and thin, and even strip the soil bare. As crane fly larvae eat the roots and lower stems of plants and other vegetation, the surface layer of the soil held together by the plant’s roots can turn yellow, signaling damage on the whole plant. Once pulled lightly or even accidentally, these grasses, plants, and vegetation that have been eaten upon can loosely detach from the soil, as there are no more roots left for them to stay attached to the ground. During the autumn and winter seasons, crane fly larvae often damage farmers’ plants and vegetation, and it gets worse in the spring, when the larvae are completely grown. Skunks and moles may excavate the ground to forage and eat crane fly larvae. This event, however, worsens the damage that crane fly larvae are already bringing to plantations and gardens.
Do Crane Flies Eat Mosquitoes?
Crane flies are not generally known to eat mosquitoes. However, there are some types of crane fly larvae that feed on mosquito larvae, although this instance only happens rarely. Some crane fly larvae may eat mosquito larvae, which is where the nicknames “mosquito eater” and “mosquito hawk” come from. Mature crane flies don’t sting humans or other animals, and because mosquitoes are not a regular part of their diet, it is crucial to stress that they are completely harmless to both. Carnivorous crane fly larvae, on the other hand, may prey on mosquito larvae, tiny insects, aquatic insects, and other invertebrates, depending on the species.
How Do Crane Flies Eat?
Crane fly larvae have distinctive and customized parts of their mouths that help shred their food into tiny little pieces. Some crane fly larvae also gather food from decaying matter found in animal feces and other decomposing materials.
How Big Can Crane Flies Grow?
As crane flies are longer than mosquitoes, they can grow up to 1.5 inches in length, with a wide wingspan that can extend up to 2.5 inches. Crane fly larvae, on the other hand, range from 5 mm to 4 cm before transforming into pupae. Because of their thick skin during their larval stage, crane fly larvae are frequently called “leatherjackets.” The crane fly larvae also lack legs and resemble worms in appearance.
