Crane flies are often mistaken for giant mosquitoes due to their similar appearance. However, these large, gangly insects play a different role in the ecosystem. Despite being commonly referred to as “mosquito hawks” or “skeeter eaters,” adult crane flies do not actually consume mosquitoes source.
Their larvae, known for causing damage to lawns, also have a different diet. Preventing this damage can be achieved through simple maintenance and irrigation practices source. So, although they may look menacing, crane flies pose no threat to mosquitoes and have a unique place in the ecosystem.
Crane Flies and Mosquitoes
Misconceptions about Mosquito Eaters
Crane flies are often mistaken for mosquitoes due to their long legs and elongated, slim bodies1. They are known by various nicknames, such as “mosquito hawks,” “skeeter eaters,” and “daddy long legs.” Despite these nicknames, crane flies do not consume mosquitoes2.
Although they may appear similar to mosquitoes, crane flies are mostly harmless to humans. They do not bite, sting, or transmit diseases3. Adult crane flies live for a short period of time, usually about two weeks4.
There is a widespread belief that crane flies are predators of mosquitoes. This is not true. In fact, they serve as a food source for insectivores like frogs, swallows, and armadillos5. They play an important role in maintaining a healthy ecosystem.
Crane Flies vs. Mosquitoes: A Comparison
Feature | Crane Flies | Mosquitoes |
---|---|---|
Size | 0.5-1.25 inches1 | Smaller |
Diet | Not predatory5 | Blood feeders6 |
Harmful to humans | No3 | Yes6 |
Lifespan | Up to 2 weeks4 | Variable7 |
Key characteristics of crane flies:
- Long legs and slim bodies
- Do not consume mosquitoes
- Harmless to humans
- Short lifespan
In conclusion, crane flies are not predators of mosquitoes. They do not eat mosquitoes, and both insects have different feeding habits and overall characteristics. It is essential to differentiate between the two organisms to understand their roles and functions in the ecosystem.

Life Cycle of Crane Flies
Eggs and Larval Stage
Crane flies start their life cycle as eggs, which later hatch into larvae. The larvae, also known as leatherjackets, are small and brown with a segmented body. They can be tan, gray, or greenish, with a definite head and tiny, fleshy projections at the hind end. Despite not having legs, crane fly larvae are able to move and feed.
Crane fly larvae primarily inhabit moist soil, where they feed on decaying organic matter and plant roots. Some species might have multiple generations per year, such as the marsh crane fly, while others, like the common European crane fly, only have one generation annually.
Pupae and Adulthood
When fully grown, the larvae metamorphose into pupae which are gray to brown in color and about 1 inch long. Pupae do not feed and eventually transform into adult crane flies.
Adult crane flies have long legs and elongated, slim bodies that are often mistaken for mosquitoes. They typically range in size from 0.5 inches to 1 inch, depending on the species. Adults have very short lives, usually lasting just one to two weeks. Contrary to popular belief, adult crane flies do not feed on mosquitoes; instead, they consume nectar or may not feed at all in their brief adulthood.
In summary:
- Larvae:
- Small and brown with segmented bodies
- Feed on decaying organic matter and plant roots
- Inhabit moist soil
- Pupae:
- Gray to brown color
- Non-feeding stage
- Adults:
- Long legs and slim bodies
- Life span of one to two weeks
- Do not feed on mosquitoes

Crane Flies’ Diet and Feeding Habits
Adult Crane Flies
Adult crane flies belong to the family Tipulidae and are members of the order Diptera. They have a slender, mosquito-like body with long legs. Interestingly, adult crane flies do not feed on mosquitoes nor do they have a substantial diet. Their primary purpose is to mate and lay eggs.
Larval Stage of Crane Flies
The diet and feeding habits of crane fly larvae are significantly different from the adults. Larvae, also known as leatherjackets, mainly feed on:
- Grass: They consume plant material in various stages of decomposition.
- Roots: Crane fly larvae feed on the roots of grasses and other plants, which can cause damage to turf and lawns.
- Soil debris: Organic matter found in soil is an important food source for the larvae.
- Algae: They might feed upon algae in moist environments.
Different species of crane flies might have varying preferences for food sources during their larval stage. The impact of their feeding can be significant, particularly on lawns and grassy areas, as they consume the plant roots and other organic materials close to the soil surface.
In summary, adult crane flies do not have a significant diet, while their larvae feed on various plant materials found in the soil, such as grass, roots, and algae. The feeding habits of crane fly larvae can sometimes cause damage to lawns and other grassy environments.
Crane Flies’ Role in the Ecosystem
Predators and Prey
Crane flies play an important role in the ecosystem as a food source for various insectivores. Some of their predators include:
- Frogs
- Swallows
- Armadillos
- Spiders
- Fish
- Birds
Contrary to popular belief, crane flies are not significant predators of mosquitoes, and they are not called “skeeter eaters.” Instead, they are mostly harmless creatures that do not bite humans or pets 1.
Impact on Vegetation and Lawns
Crane flies can have both positive and negative impacts on vegetation and lawns. As larvae, also known as leatherjackets, they sometimes feed on roots and stems of plants, causing minor damage to gardens, meadows, and pastures2. However, they are also a valuable part of the ecosystem, contributing to nutrient cycling and providing a food source for other organisms.
Impact on Vegetation | Pros | Cons |
---|---|---|
Crane flies | Contribute to nutrient cycling | Can cause minor damage to plants |
In conclusion, it’s essential to recognize the role that crane flies play in maintaining a healthy ecosystem. While they may not be the mosquito-eating heroes that some people believe them to be, they serve as a crucial food source for various insectivores and contribute positively to the natural environment.
Controlling Crane Fly Populations
Natural Methods
-
Introduce nematodes: These microscopic worms can target and kill crane fly larvae. Apply them to the soil where crane fly populations are high.
-
Predatory insects: Encourage hoverflies, beetles, and other insects that prey on crane fly larvae by planting flowers and shrubs that attract them.
-
Eliminate standing water: Crane flies are attracted to moist environments, so removing sources of standing water like tires, toys, and puddles can help reduce their presence.
-
Use window screens: Installing window screens on windows and doors can prevent adult crane flies from entering your home or other structures.
Method | Pros | Cons |
---|---|---|
Nematodes | Highly effective; environmentally friendly | May require reapplication |
Predatory Insects | Chemical-free; promotes healthy ecosystem | May not control large populations |
Standing Water Removal | Disrupts breeding habitats; reduces mosquito populations too | Requires diligence; labor-intensive |
Window Screens | Physical barrier against adult crane flies | Installation and maintenance |
Chemical Treatments
-
Insecticides: Apply chemical treatments targeting crane fly larvae to your lawn or garden. Follow the manufacturer’s instructions for proper use and application rates.
-
Consider environmental factors: Crane fly populations can vary yearly due to differences in weather patterns. It’s important to take environmental factors into account before deciding on chemical treatments to avoid excessive use or overreliance on chemicals.
When selecting a chemical treatment, consider its impact on non-target species and the environment. Some chemicals may pose a danger to beneficial insects or organisms, so it’s essential to follow the recommended safe application guidelines. Remember to weigh the pros and cons of chemical treatments before using them to control crane fly populations.
Treatment | Pros | Cons |
---|---|---|
Chemical Insecticides | Often effective at reducing crane fly populations | May be harmful to beneficial insects; environmental impact |
Environmental Factors | Aids in proper treatment selection and timing | Unpredictable; requires monitoring |

Thank you for having a page for info on such things as insects and bugs. These are things that my children and I talk about and often come up with questions about. I will be returning to your page when we wonder about bugs again. And it looks like you have some animal information on here too. Thanks again.
so are you saying that there’s nothing to do about these crimes lies and just live with them their bombard in my entire garage and anytime I open the door they fly in
Thanx for the info!! I’ve been wondering if they were what many people claimed……”the eater of mosquitos'” It seems I had read an article looong time ago that they were actually male mosquitos!!
