Antlion Versus Dragonfly: An Epic Insect Showdown

Antlions and dragonflies are fascinating insects that are often found in similar environments, captivating the attention of nature enthusiasts.

These creatures, although similar in appearance at first glance, vary in many ways, including their ecology, behavior, and life stages.

Differences In A Nutshell

The antlion (Myrmeleon sp.) is best known for its larvae, commonly called “doodlebugs,” which create funnel-shaped pits to trap ants and other small insects.

Adult antlions resemble drab-colored damselflies but have clubbed or curved antennae.

Adult Antlion

Dragonflies, on the other hand, belong to the order Odonata and include many species. Adult dragonflies are generalist predators, feeding on various day-flying insects such as flies.

Known for their agility and speed, these insects are an amazing sight to behold as they skillfully navigate through the air.

While adult antlions prey on insects, their primary focus is on mating and laying eggs. Dragonflies, however, have a more predatory lifestyle throughout their life stages, with their aquatic nymphs feeding on various aquatic organisms.

Furthermore, antlions lay their eggs in sandy or loose soil where their larvae create cone-like traps, whereas dragonflies lay their eggs in water, allowing their nymphs to live in an aquatic environment.

Antlion and Dragonfly Overview

Origin and Classification

  • Antlion: Belongs to the family Myrmeleontidae and order Neuroptera.
  • Dragonfly: Belongs to the order Odonata.

These insects are related to one another but belong to different orders within the class Insecta.

Physical Appearance and Structure


  • Adult antlions have long, slender bodies and large, transparent wings.
  • Larval antlions, or “doodlebug larvae,” are oval, plump, flattened, and soft-bodied with large, sicklelike pincers on their heads.


  • Adult dragonflies have elongated bodies, large eyes, and two pairs of transparent wings.
  • Dragonfly larvae, also called “nymphs,” are aquatic, drab in color, and have small wing buds on their thoraxes.

Below is a comparison table of their features:

Typical habitatSandy or soft soilFreshwater environments
Adult wings2 pairs, large, transparent2 pairs, large, transparent
Adult eyesSmaller and less round than those of dragonfliesLarge and round
Larvae pincersLarge, sicklelike on the headAbsent
Larvae habitatBeneath soil surfaceAquatic environments
Larvae feedingPredatory, ambush preyPredatory, actively hunting
GillsAbsentLocated inside the rectum of nymphs

It is essential to note that although antlions and dragonflies have similarities in their adult forms, they show significant differences in their larval stages and habitats.

Life Cycle and Development

Reproduction and Offspring


  • Female antlions lay eggs in soil or sand
  • Larvae emerge from eggs and dig pits to catch prey


  • Female dragonflies lay eggs in or near water
  • Larvae, called nymphs, hatch and live in water

Metamorphosis and Stages


  1. Larvae: Antlion larvae, also called doodlebugs, have:
    • Six legs
    • Oval, plump, flattened bodies
    • Large, sickle-like pincers to catch prey
  2. Cocoon: Fully-grown larvae form a cocoon in the ground to transform into the adult stage
  3. Adult: Adult antlions:
    • Resemble fragile, drab damselflies
    • Have an elongated body and four intricately veined wings
    • Live for about one month
Doodlebug (Antlion larva)


  1. Eggs: Laid in or near water, hatch into nymphs
  2. Nymphs: Dragonfly nymphs:
    • Live in water
    • Grow and shed their exoskeleton multiple times (incomplete metamorphosis)
  3. Adult: Adult dragonflies:
    • Emerge from the water after approximately 25 days (can vary depending on species)
    • Live several weeks to a few months (depending on species)

Habitat and Behavior

Preferring Surroundings

Antlions and dragonflies exhibit distinct preferences when it comes to their habitat.

  • Antlions: They primarily dwell in sandy, dry soil, making it easier for them to create pit traps for ants and other prey.
  • Dragonflies: Favoring areas near water sources, such as ponds, marshes, and lakes, providing them access to their preferred prey, including mosquito larvae and small aquatic insects.

Predatory Habits

Both antlions and dragonflies are predators with unique hunting strategies.


Antlions lay in wait in their pit traps, which they create by digging into the sand or soil. When an unsuspecting ant or other small insect falls in, the antlion quickly grabs it with its mandibles and pulls it under.


Dragonflies are agile, fast fliers that capture their prey while in flight. Their long and slender forewings, coupled with their large anal region, enable them to perform complex aerial maneuvers as they hunt.

HabitatSandy, dry soilWater sources (ponds, marshes, lakes)
PreyAnts, small insectsMosquito larvae, small aquatic insects
Hunting MethodPit trapsAerial capture

Physical Adaptations

Wings and Flight


  • Short, plump body
  • Elongated, club-like antennae

Antlions have a short body and elongated, club-like antennae. Their wings are transparent, with a wingspan of about 30-65 mm and a network of veins that provide support and flexibility.


  • Streamlined body
  • Long, slender abdomen

Dragonflies have a streamlined body and a long, slender abdomen. Their wings, also transparent, have a wingspan ranging from 50-110 mm, and their structure consists of a more complex network of veins.

Comparing wing features:

Wingspan30-65 mm50-110 mm
Vein ComplexitySimpleComplex
Wing FlexibilityModerateHigh

Catching and Consuming Prey

Antlion larvae:

  • Pitfall traps
  • Mandibles for piercing and sucking

Antlion larvae catch prey through pitfall traps, with their large mandibles that are adapted for piercing and sucking. One specific prey of the antlion larvae is ants.


  • Aerial predation
  • Agile and fast flight
  • Catch prey using legs

Dragonflies are aerial predators, both agile and fast in flight. They catch their prey mid-air using their legs to form a “basket” and consume them with their powerful jaws.

Mating Process


In the antlion mating process, the male grasps the female’s wings, ensuring proper alignment for mating.


Dragonfly mating involves the male clasping the female’s head or thorax, while the female reaches the male’s reproductive organs with her abdomen. This unique formation is commonly called the “mating wheel.”

Role in Ecosystem

As Pollinators and Food Sources


  • Predominantly consume ants and other small insects
  • Larvae create intricate pitfall traps to capture prey
  • Not known for their role as pollinators
  • Provide food for larger predators like birds and spiders


  • Eat significant amounts of smaller flying insects, including mosquitoes
  • Dragonfly larvae are essential food for fish
  • Not pollinators, but do help control insect populations
  • Adults are often seen around ponds and lakes hunting for food

Beneficial and Detrimental Impacts


  • Beneficial: Control ant and small arthropod population
  • Detrimental: Can cause a decline in some insect species due to predation


  • Beneficial: Natural pest control, reducing mosquito and other insect populations
  • Detrimental: Limited; may slightly affect other insect populations through predation

Common Species and Distributions


Dragonflies belong to the order Odonata and the suborder Anisoptera. They are agile, fast fliers and generalist predators.

Some common species include the Roseate Skimmer Dragonfly, which can be found across the southern United States, including Florida (source). You can often spot them in gardens during the day.


  • Bristly legs to scoop up insects
  • Long, slender bodies
  • Large, multifaceted eyes


Antlions are part of the Neuropteran family and are related to dragonflies. Adult antlions resemble damselflies but have clubbed or curved antennae (source).

In contrast, antlion larvae, also known as doodlebugs, have a more oval and flattened appearance (source).


  • Elongated body
  • Four intricately veined wings
  • Large, sickle-shaped pincers (larvae)

Comparison Table:

HabitatGardens, pondsSandy/loose soil
Activity TimeDaytimeEvening/night

Antlions are often found in the South, where they create conical pits in sandy or loose soil. They are usually active during the evening and are sometimes called evening owlflies.


In summary, dragonflies and antlions share a place in the animal kingdom but have differences in their features, habitats, and activity patterns.

While dragonflies are typically seen in gardens during the day, antlions are more active during the evening in sandy environments.

Understanding the difference between the two can help to identify the benefits they provide to the ecosystem. It can also help to know and prevent the possible damage that they can cause.

Lovely adult antlion
Just thought you might like a gander at this lovely creature. . . clinging to a jasmine branch. . . Florida, mid-August. . . very shy . . . kept creeping to the opposite side of the branch from my camera. . . love the diaphanous wings.

Hi Diane,
Thanks for the awesome Antlion photo.

Letter 2 – Antlion

Antlion pics
Thank you for creating a wonderful site that serves so many people. Your site answered my question about the huge antlion adults I’ve been seeing. I was pretty sure they were antlions, but the size seemed to rule out antlions because I’d never seen a larva big enough to create such monstrous adults.

These pics are of one 3.5 inches long overall – far too but to be from a larva that makes the familiar funnel-shaped pit in sand or sandy soil (the pit would be a foot across).

Can you tell me where these larvae live, what they look like and what they eat? I suppose they would take forever to get this big eating the occassional ant. What could they be eating, grasshoppers?

Feel free to post the pics if you want, although you already have some nice ones. Maybe this is a different species. By the way, the antlion/lacewing-looking larva from Thailand could still be an antlion, though found on a bush and not in the soil.

I’ve seen antlion larvae crawling on trees, bushes, and rocks, possibly looking for better soil. They are awkward, but they get around. Lacewing larvae are far more agile, so observing the larva in question might help identify it.

Now if you can get that photo to move… Thanks again for a great site,
Martin Adams

Hi Martin,
Thank you for your wonderful letter and your gorgeous Antlion image. Adults, according to the Audubon Guide, drink nectar, eat pollen, or do not eat at all. Eric Eaton provided this information:

“Ok, before I forget, the ant lion is Vella fallax, or another species in the genus Vella. Yes, they are huge! Remember, in North America, only the larvae of the genus Myrmeleon make the pits.

That means the larva of THIS beast must simply wait in ambush somewhere, perhaps half-buried on the surface of the sand.”

Letter 3 – Antlion Studying Algebra!!!

Bug studying geometry
Location: Sulpher Springs Valley, Cochise County, Arizona

This beautiful insect landed on my mother’s notes for her Geometry students.

I’d assumed it was a dragonfly, but this is southeastern Arizona near the Cochise Stronghold (in the Dragoon Mountains) and the nearest source of water is a small pond which I believe is man-made.

I searched websites of Arizona dragonflies and came up with nothing, and someone said it was not a dragonfly (though they didn’t know what it was). I don’t know if any genus has a penchant for geometry, so I suppose the setting isn’t much help!

Signature: Timothy J


Hi Timothy,
Thank you for submitting such a humorous and amusing photograph.  Though it superficially resembles a Dragonfly, this Antlion is not even closely related.

Thanks for the very quick response! My mother corrected me and said she thinks she was teaching Algebra, not Geometry, though the appearance of Pi had me fooled.

So if scientists ever use this photo for behavioral studies in entomology it is Algebra, not Geometry, which the Antlion has an affinity to, which I might have guessed if the climates of Arizona and Arabia (from which Algebra comes)  are to be compared.

For reference, two common insects in the vicinity are the notorious Fire Ant, and the Horse Lubber (which we refer to as the “Mexican Grasshopper,” perhaps improperly).

You can verify our identification on BugGuide.  If you and your neighbors are not familiar with the winged adult Antlion, perhaps you recall as a child playing with the larvae, commonly called Doodlebugs, which dig a pit in loose sandy soil. 

The saber-jawed larva buries itself at the bottom of the pit and waits for unwary insects to tumble into its jaws.

Hi there! My son and I have been visiting this site ever since he started showing interest in bugs (he LOVES them).

We looked over your site trying to identify this one and the closest we came was an antlion (unless we missed something…there are a lot of bugs!). Were we right?

This guy was nearly three inches long and appeared on the exterior wall of our house in July. Thanks!
Signature: M. Conway



Dear M. Conway,
You are correct that this is an Antlion, and we believe we have correctly identified the species as
 Myrmeleon exitialis based on photos posted to BugGuide and this statement on the genus page of BugGuide

“6 eastern and 5 western spp.; M. exitialis is the only one that ranges into Canada.”  BugGuide also notes:  “the only genus in our area whose larvae make the funnel-shaped pits.”

I have never seen this bug before. Is it some kind of dragonfly?
Signature: Nikon



Dear Nikon,
You are not the first person who has written to us mistaking an Antlion for a Dragonfly.  In our minds, the greatest similarity they possess is the way the wings move, but not the way the wings are held. 

The wings of both orders, Neuroptera and Odonata, are able to move independently of one another.  Of Neuroptera, BugGuide states:  “Four membranous wings: FW and HW about same size or HW a little wider at base;  wings usually held rooflike over body at rest; wings generally with many veins.” 

Of Dragonflies in the suborder Anisoptera of the order Odonata, BugGuide states:  “Wings usually held outstretched horizontally at rest. Hindwing is broader at base than the forewing.

Male has three terminal appendages on abdomen; female has only two.  Males and females often colored differently.

Details important to identification include face color, eye color, color and markings on the thorax and wings, color of the pterostigma (small colored area near the front edge of the wing), color and markings of the abdomen and shape of the abdomen.

Recently emerged (teneral) individuals are often pale, unmarked, and impossible to identify until they develop the adult color pattern. Some change color several times on the way to sexual maturity (within a few days); some change color with temperature, and some also change color after death.” 

Additional differences include the complexity of metamorphosis.  Dragonflies have incomplete metamorphosis with aquatic nymphs known as Naiads.  Antlions have complete metamorphosis which includes a dormant pupa, and the terrestrial larvae are known as Doodlebugs.

Someone suggested it could be a salmon fly. It’s similar but not the same as the photos I’ve found. It is on my front porch. No water nearby, though we’ve had a little rain this past week.

Neighbors down the street have a pool but would like fly eggs to survive the chlorine. Even with rain, it’s very dry in zip code 86326.

Dear Bug aficionado,
This is most definitely NOT a Salmonfly.  It is an Antlion in the family Myrmeleontidae and we believe we have correctly identified it as
Vella fallax thanks to images posted to BugGuide where it states: 

“very large, wingspan to circa 120 mm, with tropical specimens even larger.”  Antlion larvae are sometimes called Doodlebugs.  The larvae of many species lie buried in the sand at the bottom of a pit where they wait with only their mandibles exposed for hapless creatures to fall into their jaws. 

We suspect the creators of the “graboids” from the movie Tremors used Doodlebugs as inspiration.

Thank you! I used to recite the “doodlebug” poem when I was a child visiting cousins in NC. I had no idea they were ant predators.

I and my friends keep disputing whether it is a dragonfly or not my mother passed away on Sunday and Monday at 1 AM and there was this insect flying around at my window pain and I’m just curious what kind

Signature: The truth



Dear The Truth,
This is an Antlion, and it is more closely related to Neuropterans like Lacewings and Owlflies than it is to Dragonflies, which belong to a distinctly different insect order.

  Many Antlion Larvae, which are commonly called Doodlebugs, live with only their mandibles exposed at the bottom of a small pit they excavate, awaiting Ants and other insects to fall into their waiting jaws. 

We just posted several images of Bee Flies from Los Angeles that parasitize the pupae of Antlions.  We don’t see many Antlions, but we do see Bee Flies, leading us to believe our Antlion population is being kept in check by the Bee Flies. 

Your Antlion may be Vella fallax based on this and other BugGuide images.
