Lacewings are one of the most important pest controllers and beneficial insects in the world. Here, we tell you everything you might like to know about them.
A common generalist predator in North America, Lacewings are considered to be a gardener’s friend.
There are about 1300 species of lacewings spread across 87 different genera around the world.
Lacewings are one of the most economically important families under the order Neuroptera, thanks to their ability to keep pest populations in control.
Let’s dive into it right away and find out more about these helpful insects.
What Are Lacewings?
Lacewings are a large group of insects under the order Neuroptera, known for their insectivorous feeding habit.
They feed on a variety of common garden and agricultural pests during the larval stage of their lives.
While there are more than a thousand different species of lacewings, we can broadly divide them into two families – green lacewings and brown lacewings.
All lacewing species share several common characteristics, such as chewing mouthparts and two pairs of wings.
Divided into three segments like all other insects, their long and thin bodies are akin to that of a dragonfly.
However, unlike dragonflies, lacewings keep their wings folded over their backs. These insects earn their name from the veins that crisscross their transparent wings to create a lacy appearance.
Types of lacewings
When talking about lacewings, people usually mean the green lacewing family.
They’re much more common than brown lacewings and are often called “common green lacewings” and “common lacewings.”
Scientifically known as Chrysopidae, this family comprises several genera, among which Chrysopa and Chrysoperla are the most common in North America and Europe.
Green lacewings grow up to 0.50 to 0.75 inches and feature a slender, greenish body with delicate and long antennae.
They have copper-colored eyes that have earned them the name “golden-eyed lacewing,” too. Another common name for the green lacewing is “stink fly”, thanks to the unpleasant odor they release in self-defense.
Many species of green lacewings turn brown as they age, which makes them impossible to distinguish from brown lacewings visually.
These lacewings belong to the family Hemerobiidae and share a similar appearance as green lacewings apart from the color difference.
They have brown bodies, as their name indicates. The wings may sometimes have dark spots too. Like green lacewings, the brown ones feed on various common plant pests too.
However, they are relatively rarer, and the chances of sighting them in your garden are lower too.
The brown lacewing larva displays an interesting behavior – it carries various debris, including bits of its prey, using hooks and bristles on its back.
Such behavior has led to people commonly referring to these insects as the “trash bug”. By camouflaging themselves with the debris, brown lacewings can stay hidden from predators and prey alike.
How To Identify Green Lacewings That Have Turned Brown?
Some species of green lacewings change their color as they age, taking up a reddish, grayish, or brown shade.
This usually occurs during early spring, making it difficult to distinguish the color-changing species from the actual brown lacewings.
Here are some other differences between brown and green lacewings besides their colors:
- The coastal cross veins on the wings of a brown lacewing are Y-shaped, while a green lacewing has straight and unbranched coastal cross veins.
- In brown lacewings, the first abdominal segment is longer than the second and third ones. This makes their necks more prominent as compared to green lacewings.
- Green lacewing larvae have an empodium (a trumpet-like appendage) between their tarsal claws and the end of their feet. This appendage is missing in brown lacewings.
Where Do lacewings Live?
Thankfully, these natural predators are present all over the world. You can find different lacewing species throughout North America.
The US and Canada house 87 different species of lacewings distributed across 14 genera.
As for their habitat, lacewings typically prefer plenty of vegetation. You’ll usually find them in wildlands, gardens, tree crops, farmlands, and fields.
This is because the adult lacewing lives on a diet comprising nectar, honeydew, and yeasts – all of which they have to collect from plants.
What Do They Eat?
It’s the feeding habit of the lacewing larvae that make these insects so beneficial.
Also known as aphid lions and aphid wolves due to their ability to eat hundreds of aphids, they feed on a variety of soft-bodied insects.
These include common garden pests like aphids, mites, caterpillars, mealybugs, leafhoppers, lace bugs, thrips, scales, etc.
Although not all lacewing species display an equally impressive appetite, many of the common ones can eat up to 200 aphids in a single week.
The Green lacewing adult usually feeds on plant-based foods like pollen, nectar, and honeydew.
However, some of them are predaceous and also prey on the soft-bodied insects mentioned earlier.
The brown lacewing adult and larvae are both insectivorous and can help with pest control too.
What is the Lifecycle of Lacewings?
Lacewings have a rather short lifespan, ranging from about six to ten weeks in total.
They undergo a full metamorphosis, consisting of four life cycle stages like other insect species, emerging as larvae and pupating into adults.
- Eggs: Adult female lacewings lay about 100 to 300 eggs on average, usually on plant hairs or underneath leaves. Although a green lacewing egg is an initially pale green, it turns gray before hatching.
- Larvae: This is the most important stage in the lacewing’s role as a natural pest control agent. Lacewing larvae range from yellow to brown, with a mottled appearance. Their spindle-shaped structure is somewhat similar to that of alligators, and they even have spines at the sides. Lacewing larvae possess strong mouthparts that allow them to kill their prey and inject them with digestive juices.
- Pupae: After three instars and two to three weeks of development, the lacewing larvae are mature and ready to pupate. Lacewing pupae are usually green, surrounded by opaque, silken cocoons that are yellow or white. This stage lasts around five days.
- Adults: The adults emerge at the end of pupation and live for 20 to 40 days. As mentioned earlier, they have green or brown bodies and large eyes. During the few weeks, they spend as adults, the lacewings mate and lay eggs for the next generation to hatch from.
Where Do They Lay Eggs?
Female lacewings might lay the eggs in groups or singly. Many species of female lacewings lay them individually on the tips of stalks.
This helps prevent the newborn larvae from resorting to cannibalism. You may also find clusters of lacewing eggs around prey infestations.
Do They Bite or Sting?
Lacewings do not possess stingers and are, therefore, incapable of stinging. However, their bites are still painful and can cause a red and itchy bump on the skin.
This isn’t anything serious, and you’ll lose the bump and the discomfort within a day.
Adult lacewings don’t bite humans very often, but the larvae might get provoked if you come in contact with them while working in the garden.
Are They Poisonous or Venomous?
Although their bite can be painful, lacewings aren’t venomous or poisonous. The itchiness and the bump are caused by the caustic acid in their saliva.
Although the saliva is corrosive enough to break down their prey and make them more digestible, it doesn’t pose much of a threat to humans.
Are They Harmful to Humans as Pests?
Lacewings are quite the opposite of what we’d define as a pest. Many gardeners even buy lacewings or raise them from eggs to use for pest control purposes.
With their seemingly insatiable appetite and their tendency to lay hundreds of eggs, lacewings can quickly clamp down on garden pests.
If you find lacewing eggs in your garden, you can spread them around plants prone to pest infestations.
Can They Come Inside Homes?
Lacewings generally tend to live outdoors, where they can easily find suitable food sources.
However, the adults often enter homes in autumn and winter, drawn by the warmth.
They seek cozy hibernation sites around this time, and warm indoor environments are perfect for this.
What Are Lacewings Attracted To?
Adult lacewings are typically drawn to places with a variety of colorful flowers. As mentioned previously, they need pollen and nectar to sustain themselves.
If you’re trying to attract more lacewings to your garden, planting flowers like Queen Anne’s lace, goldenrod, marguerite daisies, cosmos, and yarrow should help.
How To Get Rid of lacewings?
You don’t need to get rid of lacewings from your garden as they’re harmless and help protect your plants from pests.
However, if too many of them start entering your home during the colder months, it might pose a problem. The best way to get rid of them is to pick them up by the wings and gently release them outside.
If there are too many lacewings for manual removal, you may consider using pest control products instead.
Interesting Facts About lacewings
Before I end finish, here are some interesting facts about these delicate insects that you might want to know:
- Lacewings kill their prey by piercing them with needle-like teeth and injecting digestive juices. The juices dissolve the prey’s body from the inside, which the lacewing can then suck up.
- Adults have ears located at the base of their wings and are capable of hearing the echolocation signals released by bats. This gives them time to close up their wings and potentially avoid detection.
- When lacewings feel threatened, they release an unpleasant smell. It helps them deter predators from eating them.
I hope you enjoyed learning about this delicate insect and that the article has answered all the queries you had about them.
If you’re a plant parent, feel free to get some lacewings in your garden. By feeding on adult pests, their larvae, and insect eggs alike, they’ll significantly reduce your pest control expenses.
You’ll have to stay away from using pesticides, but that’s not necessarily a bad thing. Thank you for reading, and I hope you’ll manage to include lacewings in your pest control strategy.
Over the years, lacewings have been a hot topic for our readers.
They have asked about various things related to these beneficial insects, including where they live, what they eat, and even where to buy lacewing eggs or how to bring them to gardens.

This bug is about 1/4” across and bites!
On the lower portion of one of your somewhat blurry images, it is possible to make out the mandibles of the insect that created this elaborate protective covering from debris. This is a camouflaged Lacewing Larva, and we have received numerous reports of people being bitten by Lacewings and Lacewing Larvae. Both adults and larvae are predatory and they are important natural predators of Aphids and other plant pests. Lacewing Larvae are called Aphid Wolves and Green Lacewings are sometimes called Goldeneyes.

A friend of mine recently found a strange bug inside a cabin she’s staying at for the weekend, and we’ve been trying to find what kind of insect it is but with no luck. It moves slowly, is slightly smaller than a dime, and is covered in shiny black bumps, so that it almost looks like a miniature blackberry. We can identify small pincers but she wasn’t able to see how many legs there were. Someone mentioned that it could be a transport unit for ticks, but I wasn’t aware that there was such a thing. Any insight would be greatly appreciated. Thanks!
This is a predatory Lacewing Larva, and larval Lacewings frequently camouflage themselves with the carcasses of prey. It appears as though your individual has been eating Black Ants, which explains its resemblance to a blackberry.

Several days ago I released some ladybugs on my milkweed plants. They have all disappeared, which is befuddling as the plants are in an enclosed pool cage and there is a generous supply of aphids to munch on. Today (September 27, approximate temperature 87° ) I noticed these beauties. I can’t imagine this is any part of the ladybug lifecycle. I was wondering if you might know what they are? They appear to be about the size of a pencil eraser and seem to get around quite well. I can’t tell if they are eating the aphids or not, although that would be great.

While you might be distressed at the disappearance of your Ladybugs, you should be aware that Lady Beetles can fly and they can also be adept at squeezing through small openings in your enclosure. On a positive note, this is a camouflaged Lacewing larva, sometimes called an Aphid Wolf, and many gardeners believe Lacewings, both adults and larvae, are more effective at eating Aphids than Lady Beetles are.
Letter 5 – Debris Carrying Lacewing Larva
Have I discovered a new bug?!
The diameter of the ball on top looks like mabe 1.5 mm. When not walking it retreats to some extent under it’s ball. When it walks, viewed from above it looks as though it is riding on wheels, so perfectly smooth is its motion. I found it in a canyon in Los Angeles. Thank you very much.
This is a Debris Carrying Lacewing Larva. Some Lacewings carry debris, including the carcasses of prey, as protection and camouflage.
Letter 6 – Debris Carrying Lacewing Larva
Need bug identification please
Hi, my husband and I discovered the weirdest, oddest bug we have ever seen in our lives tonight. See attached pics. At first we thought it was some sort of spider with a whole bunch of dead ants on it’s back, but then discovered that it has jaw-type pinchers. It’s like a moving junk bug with a mess of “stuff” on it’s back. I actually saw it take a part from a dead ant that fell off of it’s back and put it in it’s pinchers and reattached it to it’s back. It’s like it was camouflaging itself (?). The bottom of it looks grey and from what we can tell, there’s no tail – just “junk” and ant parts on it’s back. It seems to be able to crawl & attach to anything and crawl around. It’s pretty small, about the size of an eraser on the top of a pencil. Thanks in advance – we’re real curious to know what this is!
This is a Debris Carrying Lacewing Larva. Not all Lacewing Larvae exhibit this characteristic. Some Green Lacewings in the Family Chrysopidae exhibit this behavior, and BugGuide has numerous images.
Letter 7 – Debris Carrying Lacewing Larva
Okay, what’s this one?
Thank you Daniel,
I was surprised and gratified to hear from you – and of course you’re very welcome to the photo! I have a few additional shots for you – and I don’t have any idea as to what this might be. This tiny critter had evidently glued a lot of other bug parts (even a few minuscule snail shells) onto its back and was waiting to ambush something even smaller when he first caught my eye. Any ideas?
Hi again Henry,
This is a Debris Carrying Lacewing Larva. Some Green Lacewings in the family Chrysopidae have larvae that camouflage themselves with debris, including the remains of their prey.
Location Request: (07/18/2007) Debris carrying lacewing larva
I wanted to tell a malacologist friend about the neat larva that has some snailshells cemented on him. Did Henry tell you where it was from? The small white shell seems to be a Vallonia, I think maybe Vallonia eccentrica. Thanks,
Update: (07/18/2007) Lacewing location
I took those shots in Titusville, Florida, about six or seven years ago. I saw several at that time, but haven’t noticed any more since then, which is too bad, since I could probably take better photos now. Again, thanks in advance, – and keep up the good work! Henry
Letter 8 – Debris Carrying Green Lacewing Larva
Bug with carapace made of OTHER BUGS!!
Mon, Oct 13, 2008 at 6:03 PM
Dear What’s That Bug Man, my computer just crashed, so if you’re seeing this email for a second time, that’s why. This very tiny (about 1/2 the size of my little fingernail) bug is, from the underneath (not shown in these photos), gray and somewhat louselike. From above, it appears to be wearing a little house made of DEAD, OTHER BUGS. The false carapace is topped with a whitish object–an egg? From the side, I can see its little legs–a lot of them–and pincers, but I can’t tell if the pincers are its own or belong to one of the dead bugs. You helped me once with my Very Special Spotted Bug (an ironclad beetle) and I hope you can help me again! Thank you! p.s. I love the updated website!
Dripping Springs, TX (west of Austin)
Really? Well all right then! We have lacewing eggs all over the place, even inside. But what the heck is up with it carrying around the little house made of dead bugs? Do you have information about this? It’s quite fascinating. And quite bizarre. I desire explanation on top of identification! But perhaps I can do that for myself, now that I know what bug to research!
Thank you so much for your speedy reply! Your website is one of my constant favorites.
We often write a very short response before doing a lengthier answer for posting. This is a Green Lacewing Larva. Some species carry debris like your specimen. According to BugGuide: “It seems that the trash carried by these larvae confers some protection against predatory ladybeetles. “
Letter 9 – Debris Carrying Green Lacewing Larva in Australia
Friend of The Ants
January 15, 2010
This unidentified creature was found along an ant trail in the window frame of our bathroom in the Northern Beaches area of Sydney, Australia. Although it looks like a lump of glue with some dirt sticking to it, underneath is has six widely spaced white legs with which it moves very slowly. There were two or three of these hanging about with the ants. Any ideas?
Coastal Region, Sydney, Australia
We believe this is a Debris Carrying Larva of a Green Lacewing, and we don’t think it is a friend to the ants. It may be preying upon the ants. According to BugGuide: “It seems that the trash carried by these larvae confers some protection against predatory ladybeetles.“ The Insects of Brisbane website also contains some images of the larvae and adults of species from Australia.

Your image is awesome. This is one of the best images we have ever received of a debris-carrying Lacewing Larva.
Thanks for the kind words and the identification. 🙂
It is indeed a lacewing larva. Do you know wich region of the world it can be found ? I saw pictures from Europe and America. Seems like a quite common insect, but it is the first time i saw one of those.
Apparently there are debris-carrying Lacewing Larvae in many parts of the world, including Australia.

Awesome thanks a bunch! Shortly after I posted this I had the idea to Google “debris bug” cause I had no idea what would use literal debris and body parts. We discovered it was a lacewing larvae and we were so intrigued. I went out and put him on a plant in our garden and we watched him climb around for a few minuts. We actually got to watch him eat aphids as well! It was so cool to see life on such a small scale still taking it’s course as normal, like I wasn’t even watching!
We wish we could get away with checking our emails every two months.

Heidi and Keiffer
Hello there Heidi and Keiffer,
This is a Giant Lacewing, Polystoechotes species. These are the largest North American Neuropterans. At night they are sometimes attracted to lights which probably explains its presence in your home. According to the Audubon Guide, little is known of the life cycle.
Letter 17 – Giant Orange Lacewing from Australia
Subject: Yellow Dragonfly moth
Location: Woy Woy, New South Wales, Australia

This dragonfly looking insect flew in at about 9:30pm while very dark outside and was attracted to the light like a moth, however it looks much like a dragonfly. I’m living in the Central Coast about 1.5 hours north of Sydney.
We quickly identified your Neuropteran as a Giant Orange Lacewing or Blue Eyes Lacewing, Nymphes myrmeleonides, on the Brisbane Insect website where it states: “They have a pair of transparent wings of about equal size. When fly, they may be mistaken as dragonflies. But their wings are fold in tent shape whish dragonflies do not do. They can also distinguished by their long antenna. Adult body is orange-brown in colour, with iridescent grey eyes. The moniliform antennae are black with pale apex. Legs are pale yellow. Their transparence wings are narrow with a white marking on the wing tips.” According to OzAnimals: “It is one of the largest lacewings with a body growing to about 4 cm long and wingspan of up to 11cm. Despite the large wings, they are not strong fliers.”
Hey there, I just about 10 to 15 minutes ago submitted a photo post about a “dragonfly moth looking insect” however I’ve just been browsing online and have stumbled across the identification myself it being a “blue eyes lacewing”. So just letting to know thats one submission you dont have to worry about anymore. 🙂
Letter 18 – Lacewing Carnage
Smelly Green Fly
I’m from Wisconsin and this fly landed on my desk out of nowhere. I squished it and it instantly released this smelly odor. I’ve never seen anything like this. It smells similar to a musty old basement (if not worse). Can you tell me what kind of bug this is? (Pictures are attached) Thanks!!
If you hadn’t squashed this beneficial Lacewing, your sensitive nose would not have been subjected to the offensive odor it emitted as a defense mechanism. Lacewings are important biological control agents for Aphids, which if their populations were left unchecked, just might overpopulate the planet. We are going to take the liberty and be blunt here. If someone squashed you, you probably woundn’t smell very good either.

Blue bug with translucent wings
September 6, 2009
I was laying in bed with the TV on at night and my cats kept indicating there was a bug (they usually meow a certain way). I looked at the ceiling and could see the shadow of some sort of flying bug. I turned the light on and the bug was not there. I looked hard for it and couldn’t find it. I turned the light and a minute later the cats were freaking out again. I looked up and there was the shadow. I turned the light on again and I could not see it. So I stood on the bed and looked closer at where the shadow at been. There was a small flying bug, about an inch long and maybe 2 inches or width, with almost translucent blue/green wings. I killed it immediately but it was odd b/c I’ve never seen anything like that.

This Lacewing is a [relatively] harmless, beneficial predator and it did not deserve to be smashed for entering your home.
Letter 20 – Thai Caterpillars identified as Leopard Lacewings
I saw these caterpillars while on vacation on the island of Samui in Thailand. I thought they were beautiful and wanted to know more about them.
We have no idea what these caterpillars are, but they are so beautiful, we are posting the letter hoping someone will identify them. If we were on a game show and had to venture a guess, we would say a butterfly in the Nymphalidae Family. Certain members of that family have spines and social behavior, like the Mourning Cloak.

Here are the adult’s. The one with more colour I think is the male.
Thanks for sending some butterfly images to accompany the Caterpillar image you sent previously. One image appears to be a male Leopard Lacewing, Cethosia cyane, but we believe the other image is another species of Brushfooted Butterfly. We quickly identified it as a Jewelled Nawab Butterfly, Polyura delphis, thanks to Getty Images. Learn About Butterflies uses the common name White Nawab and states: “The butterflies are characterised by their distinctive wing shape with twin tails on the hindwings, a feature strongly reminiscent of the African Charaxes. Most have dark brown uppersides with bands of dazzling creamy white which vary in size and shape from one species to another. These bands are usually repeated on the underside in a beautiful shade of pale green, but in the case of delphis the underside is white, and marked with orange, yellow and grey spots and lunules, hence its alternative name the Jewelled Nawab. Polyura delphis is one of the scarcer species, and is found in Assam, Sikkim, Myanmar, Thailand, peninsular Malaysia, Sumatra, Sabah, Brunei, Kalimantan, Palawan and Java.”

What a fantastic site you guys have!!! I just found out it the pic I sent is a Ribbon Winged Lacewing, a Neuropteran – could you help with the species id? Have now attached another pic, which presumably are its eggs (since they have the characteristic stalk-shape, just like other lacewings). Best,
Hey Guys, I stay in Mumbai, India and found this fly (?) in my house. At first glance, it looks like a large mosquito but has these two long appendages that stream behind it as it flies around in a seemingly “drunken” fashion, ducking and weaving crazily about.

Letter 23 – Two Neuropterans from Capetown: Antlion and Ribbon Winged Lacewing
I’m living in CapeTown, South Africa and stayed in Cederberg for a week in December 2005 I managed to capture a dead species of one unidentified insect (which looks like a dragonfly/normal flying insect with its second pair of wings slightly modified)and missed the other (which resebles a cross breed butterfly/dragonfly??), but i did manage to capture them both on camera. Please could you have a look and see if you’ve ever come accross something similar or the same. I have contacted our Dr’s at the museum of CapeTown SA. but i still havnt recieved any reply yet??? Anyway maybe you guys could come up with something and hopefully get back to me. Many thanks
|Ribbon Winged Lacewing
One of your exotic insects is an Antlion. We are going to see if Eric Eaton will help us on the long tailed specimen. Here is Eric’s input: ” With the antlion is another Neuroptera, actually, but I can’t blame anyone for not having a clue. The Nemopteridae family is so bizarre. These are the spoon-winged, ribbon-winged, and thread-winged lacewings. I believe they are all found only in the Old World. The larvae are REALLY strange, many of them looking like giraffe-necked versions of antlion larvae!”
Many Thanks for your speedy reply, I have to say that I am a little too excited than I should be…lol, but its great to know that I’m not the only one that has seen these insects… You have a brilliant site and is great for the “ento-enthusiasts”, will be definantly spreading the word about your site, its a warm welcome from the far cry of insect websites. Many thanks and kind regards

This is an amazing insect with very long hindwings (not used in flight). At fist I thought they might be long halters, making it a fly or a mosquito. Then I noticed the net-forewings, and the resemblance to insects in the Neuroptera order. Any idea what it is? This photo was taken in Jordan.
Ribbon Winged Lacewings, also known as Thread Winged Lacewings, Spoon Winged Lacewings, or Thread Winged Antlions, are in the order Neuroptera. They are old world insects in the family Nemopteridae. Here is a nice link to some images of Lacewings on Stamps.

aegean sea coast, west anatolia, izmir, turkey
This is a Ribbon Winged Lacewing in the family Nemopteridae and the order of Neuropterans. We have no idea what the species is and a cursory search did not show any matching images online. Ribbon Winged Lacewings are also commonly called Thread Winged Lacewings, Spoon Winged Lacewings, or Thread Winged Antlions. Your photos are quite lovely and they have jumped the queue of letters that arrived November 5.
Letter 26 – Ribbon Winged Lacewing from India
Subject: Which insect is this? Pls tell if its harmful ?
Geographic location of the bug: India ; U.P.

Your letter to the bugman: Please identify this insect and tell me about it
How you want your letter signed: Imrose
This is a Ribbon Winged Lacewing in the family Nemopteridae, and we believe it might be in the genus Chasmatoptera because of a drawing posted to Wikipedia. It is not harmful. Lacewings are predators that will help control populations of other insects.

Is this a butterfly, cranefly or what?
April 29, 2010
These insects emerged recently (April – springtime) in the meadows here. They look and behave similar to butterflies except that the second pair of wings appear elongated to form tails. They are blue-green in colour with darker markings. They seem to favour the various grasses. They were quite difficult to photograph and the images are not very clear, but you should be able to see the basic shape. I also took some video.
Southern Peloponnese, Greece
Even with the blurriness of your photo, we are quite certain this is a Spoonwing Lacewing in the family Nemopteridae. We posted an example from nearby Turkey this past June. The Nemopteridae website devoted to the family identifies it as Nemoptera bipennis.
Hi Daniel, thanks very much for the info on spoonwing; its been driving me mad not knowing, yours gratefully sue

I have seen many of those things flying around the countryside, but I was always wondering what exactly is that thing. To me as a kid, it was a hybrid of butterfly and mosquito(haha), but when I grew up I realise that this is not possible, so I came up with an other idea. I suspect that this is a kind of “liveloula” (dragonfly).
Signature: I do not understand that question. By the person who will find out what that thing is….
This unusual creature is a Spoonwing Lacewing, possibly Nemoptera bipennis. Your individual is missing one of its distinctive tails.Hello Daniel,
Thank you very much for your reply. I really appreciate it. Unfortunately this little guy died during the night, for unknown reasons, but at least now I know the name of this beautiful insect. I am sorry about the missing wing/tail I forgot to mention about it, but you figured it out anyway…

Hello, I saw this very interesting creature flying above me, than managed to catch it on cam. Do you know what it is? I’d really appreciate it.
This delicately beautiful insect is a Spoonwing Lacewing or Threadwing Lacewing in the genus Nemoptera.
Thank you so much for your quick response, you are awesome!

Saw this ”Butterfly” on a trip to the ancient ruins of Perge in Turkey, near Antalya. Was spotted in late may around mid day. Have tried to look it up on various site but have had no luck!
We have, in the past, identified creatures like this as Spoon-Winged Lacewings, but a new web search has turned up the common name Thread-Winged Lacewing, Nemoptera sinuata, on a photo taken in Turkey on the TrekNature Website.
Letter 31 – Thread-Winged Lacewing from Spain
Subject: CAN ANYBODY IDENTIFY THIS BUTTERFLY PLEASE?

I photographed this butterfly on the mountains above Benalmadena (Spanish Costa Del Sol) early this week but I have no idea what it is and Googling ’Long Tailed Butterfly’ does not bring any results.
The photo shows the underside of it’s right hand wings and the very long ’tails’ which must surely help in identification.
Do these long ’tails’ have a scientific name?
Many Thanks in anticipation.
Though it looks like a butterfly, it is not. Rather, it is a Thread-winged Lacewing or Ribbon Winged Lacewing, Nemoptera bipennis, which you can view on the Panoramio website as well as numerous other places on the internet.
Wow, I had no idea it wasn’t a butterfly. Many thanks for your reply – and so quick too!

Thank you very much for the identification. At the risk of being greedy, could I also ask you to identify this lovely two tailed fly. Found near a stream in the same area, its wingspan and tails are about two and a half inches long. What does it use these amazing tails for?
Hi again Peter,
This is a Thread-winged Lacewing or Ribbon Winged Lacewing, Nemoptera bipennis. We are not certain why the wings have evolved to have such delicate tails.
Many thanks for this. It is wonderful to have your expertise available on the internet.
With bets wishes, Peter

Sciencebase Q&A (from David Bradley)
UPDATE: We think it is: Nemoptera bipennis
A photographer friend snapped the attached insect. The presence of long
“halteres” suggests it is a member of the diptera family, possibly
related to lacewings…not sure. I am hoping that Daniel will be able to
ID it quickly and give us an excuse to mention his book again 😉
Please let me know as soon as possible
Hi David and Angela,
You are mostly correct. This is a Spoonwing or Threadwing Lacewing, and it may be Nemoptera bipennis, though there is no location provided for the photograph. If the photograph was taken in Europe or Western Asia, the chances are very good it is Nemoptera bipennis. The error is in the insect order. Diptera is an order, not a family. Diptera is the family of Flies, and halteres are the vestigial second pair of wings that are underdeveloped knob-like structures that are believed to serve to stabilize insects in flight. Most true Flies have halteres, and the name Diptera refers to the fact that most Flies only have two pairs of functioning wings. The thread or spoon wings on this Lacewing are tails on the hind wings, not halteres. This Spoonwing belongs to the order Neuroptera, not Diptera. Hope that helps.
We had a doubter.
Someone reckons N coa ranges across Greece (which is where the photo was taken) whereas N bipennis is Iberia/France…
They look almost identical to my eye…
Any further thoughts welcome, although please don’t be obliged to spend time on this.
Letter 34 – Debris Carrying Green Lacewing Larva
Moving Moss…Can you identify this Bug?
February 15, 2010
My son and I found two of these bugs in our back yard in Central Florida. At first they appeared to be small patches of moss, but then they started moving. When touched they would ball up. They have multiple legs with two pincher looking arms at the head. I do have some video of the two if you would like. They really are greyish looking with some brown spots that look like very much like sand or bark.
Winter Park, FL
We received two letters today, both from Florida, requesting that we identify this Debris Carrying Green Lacewing Larva. The larva carries debris as both camouflage and protection. You can see a photo on BugGuide with the larva showing.

Weird bugs in Afghanistan

While in some of the greener parts of Afghanistan where the camel spiders, scorpions, and giant ants are present everywhere these almost out of place insects fly around with no since of direction. I am curious to know what it is and what it is closely related to. Thnx

Your insect is a Spoonwing in the family Nemopteridae, and another common name is Thread-Wing Antlion. Spoonwings are classified in the insect order Neuroptera which also includes Lacewings, Antlions and Owlflies.
I truly appreciate you replying to my inquiry I looked forwarded to information on the insect I seen. You all do a wonderful job thank you.
Letter 36 – Spoonwing from Turkey
Unknown yellow insect
June 20, 2009
Hi, I’ve been trying to figure out what the name of this insect is, but it hasn’t been easy. I saw it on a vacation to Turkey, Marmaris, and now it’s just bugging me that I don’t know it’s name. Can you help?
This unusual insect is a Spoonwing or Threadwing Lacewing in the family Nemopteridae. It looks rather like a specimen from Portugal on the Nemopteridae website that is identified as Nemoptera bipennis.
