Mosquitoes cause irritation, disease spread, and endless summertime frustration, but nature provides powerful allies that help keep them under control. Several insects—both aquatic and airborne—actively hunt mosquitoes at different stages of their life cycle. Some devour mosquito larvae in water, while others chase down adult mosquitoes mid-flight. This guide explains which insects truly eat mosquitoes, clears up myths like crane flies being “mosquito eaters,” and reveals which predators play the biggest role in natural mosquito control.
Key Insects That Eat Mosquitoes
Nature has a surprisingly efficient system for managing mosquito populations. Many insects prey on adults, larvae, or both. These predators thrive around ponds, marshes, backyards, wetlands, and anywhere mosquitoes breed or fly.
Dragonflies (Mosquito Hawks)
Dragonflies are among the world’s most effective mosquito predators. Often called mosquito hawks, they hunt with exceptional speed and accuracy. Both adult dragonflies and their aquatic nymphs consume mosquitoes. Nymphs live underwater for months or even years, devouring mosquito larvae whenever they are available. Adults snatch mosquitoes mid-air, using their superb vision and agile flight.
Damselflies
Damselflies are close relatives of dragonflies but smaller and more delicate. Like dragonflies, both adults and nymphs prey on mosquitoes. Damselflies are not as fast or aggressive, yet they still play a meaningful role in controlling local populations by feeding on small flying insects that include mosquitoes.
Water Striders & Backswimmers
These aquatic insects specialize in surface hunting.
They eat mosquitoes primarily during the larval stage.
Common surface predators include:
- Water striders
- Backswimmers
- Water boatmen
- Pond skaters
Water striders glide across the surface tension of ponds and streams, grabbing mosquito larvae or pupae near the top. Backswimmers dive and swim upside-down, preying on larvae below the surface.
Predatory Diving Beetles
Diving beetles and their larvae are powerful aquatic hunters. Their larvae, often called water tigers, are particularly aggressive. They pierce mosquito larvae with sharp jaws and suck out the internal fluids. Adult beetles eat larvae too, although less frequently. Their presence in ponds and wetlands significantly reduces mosquito breeding success.
Flying Insects That Eat Adult Mosquitoes
Adult mosquitoes are small, fast, and difficult to catch—but several predators are specialized or opportunistic hunters that feed on them.
Robber Flies
Robber flies are fierce aerial predators capable of catching mosquitoes in mid-flight. They seize prey with long legs, inject enzymes to immobilize it, and then consume the liquid contents. They hunt many flying insects, and mosquitoes are a suitable size for them.
Spiders That Capture Mosquitoes
While spiders aren’t insects, they play a major role in reducing mosquito populations. Web-building spiders catch adult mosquitoes that fly into sticky webs. Orb weavers, cellar spiders, and garden spiders commonly trap mosquitoes—especially in humid areas where mosquito activity is high.
Bats (Not Insects but Important Predators)
Bats often appear in lists of mosquito predators, though they’re mammals. They eat mosquitoes, but they don’t rely on them as a primary food source. Instead, they consume a wide range of flying insects, including moths, beetles, and crop-damaging pests. Their presence still contributes to a natural reduction in mosquito numbers, especially near water and wooded areas.
Myths About Mosquito Eaters
Misidentification often leads to confusion about what actually eats mosquitoes. Several insects are commonly mistaken for mosquito predators—but the truth is more nuanced.
Do Crane Flies Eat Mosquitoes?
Crane flies are frequently called “mosquito eaters” because they resemble oversized mosquitoes. However, this name is misleading. Adult crane flies do not eat mosquitoes. Many species don’t feed at all, while others consume only nectar. Their larvae live in soil and feed on decaying vegetation, not mosquito larvae.
Insects That Eat Mosquito Eggs & Larvae
Mosquitoes spend the first part of their lives in water, and this stage is where they are most vulnerable. Several aquatic predators specialize in hunting eggs, larvae, and pupae before they ever become biting adults.
Dragonfly Nymphs
Dragonfly nymphs are among the strongest larval-stage predators. They stalk mosquito larvae using jet-propelled bursts and grab them using extendable jaws. Since nymphs remain underwater for months or more, they can significantly cut mosquito populations in a pond or wetland.
Diving Beetle Larvae (“Water Tigers”)
These larvae are brutal hunters that puncture mosquito larvae with sharp mandibles. Their powerful bite allows them to overpower other aquatic insects as well, making them highly effective at controlling early mosquito life stages.
Predatory Copepods
These microscopic crustaceans hunt mosquito larvae by ambushing them in still water. They are so effective that some mosquito-control programs intentionally release copepods into standing water to suppress breeding.
Water Spiders & Surface Hunters
Water spiders, along with water boatmen, pond skaters, and backswimmers, feed on mosquito larvae they encounter near the surface. They target larvae that come up for air or rest just below the waterline.
Mosquito-Lookalike Predators
Some insects resemble mosquitoes so closely that they’re mistaken for “mosquito eaters.” While they may not always feed on mosquitoes, understanding their differences helps prevent unnecessary fear or misidentification.
Crane Flies
Often called mosquito eaters, crane flies do not actually hunt mosquitoes. They have long legs and slender wings, which cause confusion, but adult crane flies usually feed on nectar—if they feed at all.
Non-biting Midges
These look like mosquitoes but do not bite or spread disease. They feed on algae and organic material and may appear in large swarms, especially around lights. They contribute to ecosystems by supporting fish and bird populations.
Phantom Midges & Mosquito-Like Aquatic Predators
Larvae of some midge species actually prey on small aquatic organisms, occasionally including mosquito larvae. They look similar to mosquito larvae but behave differently, acting as tiny predators in freshwater habitats.

Boosting Mosquito-Eating Insects in Your Area
Supporting natural mosquito predators is an eco-friendly strategy for reducing pests around your home or property. Many beneficial insects simply need suitable habitat to thrive.
Create Water Features
Small ponds, rain gardens, or natural water areas attract dragonflies and damselflies. Ideally, the water should be clean and surrounded by native plants that offer perching and breeding spots.
Add Native Plants
Flowering plants attract predatory insects like robber flies and beneficial spiders. Dense vegetation near water sources also helps dragonflies hunt and rest.
Avoid Chemical Pesticides
Chemical sprays kill beneficial predators along with mosquitoes. Reducing pesticide use encourages a stronger natural predator community, helping control pests long-term.
Encourage Biodiversity
A yard rich in plants, shade, water, and open areas supports the full chain of predators that naturally keep mosquitoes in check—from aquatic hunters to flying insect predators.
FAQs
What insect eats the most mosquitoes?
Dragonflies are widely considered the most effective mosquito-eating insects. Both adults and nymphs hunt mosquitoes aggressively. Nymphs devour larvae in water, while adults catch mosquitoes mid-flight, making dragonflies the top natural predator in most ecosystems.
Do crane flies actually eat mosquitoes?
No. Despite being called “mosquito eaters,” crane flies do not eat mosquitoes. Many adults don’t feed at all, and others sip nectar. Their larvae live in soil and feed on decaying plant matter, not insects. Their name is purely a myth.
What insects eat mosquito larvae?
Common larval predators include dragonfly nymphs, diving beetle larvae, predatory copepods, water boatmen, and backswimmers. These species attack larvae in water, preventing them from maturing into biting adults.
Are there insects that look like mosquitoes but are harmless?
Yes—non-biting midges and crane flies look like mosquitoes but are harmless. They do not bite or spread disease. These mosquito-like insects often swarm near lights or wetlands but pose no threat to humans.
Do mosquitoes eat other insects or eggs?
Mosquitoes do not eat insects. Adult mosquitoes feed mainly on nectar; only females bite for blood to develop eggs. Mosquito larvae filter-feed on algae and microorganisms in water. They do not hunt eggs or other insects at any stage.
