Insect Infestations

Crane Fly vs. Mosquito – Giant Mosquitoes or Two Different Insects?

People tend to mix up crane flies with mosquitoes due to their similar physical features. Significantly larger, crane flies can seem intimidating, but they are not as scary as our imagination depicts. Crane flies are not harmful to people, however, they can affect the health of your lawn. 

In this post, we’ll explain how to differentiate crane flies from mosquitoes and, based on that, find a proper solution to your problem. So, if you:

  • Have noticed mosquito-like insects in your house;
  • Can’t identify which kind of insect infestation you are dealing with;
  • Wish to know the proper solution to your problem;

Then keep on reading!

What are the similarities between crane flies and mosquitoes?

The biggest and the most noticeable similarity between crane flies and mosquitoes are their appearances. No wonder crane flies are commonly mistaken for large mosquitoes. These flying insects have extremely long legs, elongated faces that are often mistaken for proboscis, and widely spread wings. Unless you have both types of insects in front of you, it’s easy to assume that a large mosquito has gotten into your house.  

Just like mosquitos, crane flies can sometimes lay eggs next to water sources. They choose undisturbed water surfaces, so their larvae can be safe there and have all the important nutrients to consume for healthy development. 

What is the difference between a crane fly and a mosquito?

Despite the small resemblance in appearances and sometimes habitat, mosquitoes and crane flies have barely anything in common. If you look closer at the anatomy of a crane fly, you will notice that it has a prolonged body with slender legs. Crane flies have straight bodies, whereas mosquitoes have a bent thorax and abdomen. However, the biggest difference between the two is the size – crane flies can grow up to 8 cm long, and a mosquito is usually small, about 0.5-1.5 cm long. 

Their infestation patterns are also quite different. Even though both of the insects infest outdoor spaces, they choose their breeding grounds differently. Mosquitoes lay eggs on water, because the larvae will later feed on the microorganisms in it. Crane fly larvae, also called leatherjackets, live off plant roots, grasses, and algae. This is why they can be found in your lawn and sometimes next to bodies of water. 

Another significant difference between crane flies and mosquitoes is that crane flies do not bite. If you see one in your house, it most likely got attracted by the light and got stuck inside. Mosquitoes, on the other hand, can choose your house as a breeding ground, if they find an open-water source, and will feed on you. 

Characteristics of a crane fly

Now that you know the similarities and the differences between mosquitoes and crane flies, let’s take a look at each of them individually.

What is a crane fly?

Crane fly is the common name for any insect of the Tipulidae family. This thumb-sized flying insect has a slender body, long legs, and smoke-coloured wings. The prolonged body makes it an extremely clumsy flier, which is why their flying looks more like wobbling. 

When do crane flies emerge?

In the UK, adult crane flies emerge in late summer up until mid-autumn. For 10 to 15 days of a crane fly’s life, its sole purpose is to find a mating partner and lay eggs in a moist vegetative habitat. Shortly after, the eggs will hatch and the off-white larvae will start feeding. The leatherjackets remain in the soil throughout the winter or until they are fully grown to pupate. In 2-3 weeks of pupating, the new “batch” of crane flies is ready to reproduce.

What do crane flies eat?

The majority of the feeding happens during their larval stage. They eat plant roots, decaying leaves, and other organic matter in the soil. The adult species occasionally feed on nectar.

What are crane flies attracted to?

More often than not, we notice crane flies when we hear them banging on a ceiling, around a light source. It happens because the adult insects are nocturnal and attracted to light. On the other hand, the larvae live underground and search for roots, leaves, and grass to feed on during their development.

Are crane flies harmful?

Crane flies don’t bite people or animals, therefore they can not transfer diseases and harm people’s health like mosquitoes. However, the larvae of these flies are considered pests and can damage your lawn. The lawn can turn yellow and develop brown patches. 

How to keep crane flies away

You might try to kill crane flies with a bug zapper or even a sandal, however, it may not make any difference, because this will not put an end to the problem. That said, here is how to handle the situation properly: 

  1. Identification

    The first thing that you need to do is make sure that you are dealing with crane flies.

  2. Lawn examination

    If you suspect that you have larvae infesting your lawn, look for birds pecking the grass. They will leave a lot of small holes in an attempt to pull out the worms. Also, your lawn might start looking patchy closer to spring, as this is the time when leatherjackets feed more actively.

  3. Control

    The best way to control the crane fly infestation is by exterminating the insects during the larval stage. Nematodes are the natural and the most effective way of killing leatherjackets. All you need to do is add them to the moist lawn during spring or autumn, when the weather is not hot.

  4. Prevention.

    To make sure that the leatherjackets will not come back the next season, you need to keep your lawn healthy. Check if your garden drains well, mow your lawn regularly, and remove debris from your yard. And if you struggle to find time to maintain your garden, you can always book a professional garden maintenance service

Characteristics of a mosquito

We’ve all been bitten by a mosquito at least once. But do we really know why they need our blood? Well, let’s find out.

What is a mosquito?

Just like crane flies, mosquitoes have thin bodies and long legs, but they are significantly smaller. Using the antennae on top of their head, these insects can sense the carbon dioxide that people and animals breathe out and the movement of the air. Female mosquitoes use a proboscis, an elongated part of the month, to suck out blood. Both males and females have it. However, the male’s proboscis is too weak to pierce through skin, so they use it to drink nectar, which also makes them good pollinators. 

Mosquitoes are also quite good at flying. Their wings and high sensitivity allows them to move fast and avoid any obstacles around them. 

Are there mosquitoes in the UK?

The short answer is yes – there are mosquitoes in the UK. In fact, the UK is home to 34 native mosquito species. Luckily, there are no vector mosquitoes (those that spread pathogens), so, if you get bitten, you shouldn’t worry much. 

When do mosquitoes emerge?

Mosquitoes are seasonal pests and mainly associated with summer. However, they can start being active as early as April and continue terrorising the population until September. During this period, female mosquitoes will lay eggs. Once they are ready, they will search for an undisturbed water surface. One female can lay up to 200 eggs. Eggs will hatch within several weeks, and larvae will develop in water sources. In the next stage, the larvae will pupate, still underwater, and soon after that, adult mosquitoes will emerge.

What do mosquitoes eat?

Mosquito larvae feed on bacteria, algae, and other microorganisms in water. Pupae remain still and go through a transformation process for several days, therefore they don’t eat at all. Adult mosquitoes’ diet includes not only blood, but also flower nectar. This fact is overlooked by many, as we often see mosquitoes only when they decide to hunt on us. 

Unfortunately, their passion for blood turns some of them into dangerous transmitters of harmful and even fatal diseases. Malaria, dengue fever, and yellow fever are some of many others. Vector mosquitoes (those that transmit diseases) often thrive in hot and humid climate conditions.

What attracts mosquitoes?

The way mosquitoes choose their prey is quite fascinating. There are several criteria that make you more susceptible to mosquito bites. They include:

  • Clothing – Mosquitoes see dark and bold colours the best. Colours, such as red, black, and navy blue can easily attract them;
  • Smell – These insects are drawn to smells. Not only sweet perfumes and deodorants attract mosquitoes, but any type of human odour (sweat, for example) allows them to recognise and locate you;
  • Exercising – Mosquitoes are attracted to the carbon dioxide we exhale. When we exercise, we produce more carbon dioxide, as breathing becomes faster. Additionally, sweating can also attract these insects;
  • Body temperature – The higher your body temperature, the more chances you have to get bitten;
  • Blood type – Mosquitoes are more interested in people with type 0 blood.
 

How can I avoid getting bitten by a mosquito?

There are several proven ways to prevent mosquito bites:

  1. Dispose of any standing water

Mosquitoes breed in stagnant water. A flowerpot, uncleaned gutter, or dog bowl can serve as a perfect breeding ground for mosquitoes.

  1. Don’t let them into your house

Installing a mosquito screen on your windows or doors can prevent mosquitoes from entering your house. 

  1. Use repellents 

Different brands of mosquito repellents are available in shops and vary in concentration and active ingredients. If you spend a lot of time outdoors, search for the ones with the higher concentration. Check the instructions to find out how often you need to use it. Effective repellents should contain DEET (diethyltoluamide), Icaridin (Picardin), Lemon Eucalyptus (PMD), or IR3535.

  1. Make yourself less appealing to mosquitoes

Try to avoid dark clothing or floral perfumes. Consider wearing loose-fitting clothes, as mosquitoes can bite through clothing that fits tightly. Long sleeves, high necklines, long trousers, and skirts can save you from nasty mosquito bites. 

  1. Air-conditioning and ventilators 

Mosquitoes avoid entering properties with constant air-conditioning. Because they are cold-blooded, they seek warmer places. By turning on air-conditioning, you can suppress the mosquito activity in your house.
