Net Winged Beetle: All You Need to Know in a Quick Guide

The Net-winged Beetle is an intriguing species known for its vibrant color patterns and unique visual adaptations. These beetles, belonging to the Lycidae family, are typically soft-bodied and slow-moving with thick antennae and veiny wing covers that showcase an array of colors, often red or orange mixed with black 1. Their bright coloring and noxious odor serve as a defense mechanism by warning potential predators of their unpalatability.

One bizarre variant of Net-winged Beetles is the Trilobite Beetle, which belongs to the Platerodrilus genus (previously Duliticola), native to China, Southeast Asia, and India. Adult males of these species measure about 8-9 mm (1/3 inch) in length 2. Other species, such as the Banded Net-winged Beetle (Calopteron discrepans), feature a distinct orange color with black bands on their elytra and can be between 10-15 mm long 3.

Some fascinating characteristics of Net-winged Beetles include:

  • Vibrant color patterns (usually red or orange combined with black)
  • Soft bodies with thick antennae
  • Unique veiny wing covers held in a delta configuration 1

Net Winged Beetle Overview

Net-winged beetles, belonging to the family Lycidae, are distinctive insects found within the order Coleoptera. They are part of the suborder Polyphaga and the superfamily Elateroidea.

These beetles are soft-bodied and slow-moving. They possess unique features like:

  • Thick antennae
  • Veiny, often red/orange, and black wing covers
  • Delta-shaped wing configuration

A prime example of a net-winged beetle is the Banded net-winged beetle (Calopteron discrepans). They are typically 10 to 15 mm in length, with males being smaller than females. Adult males of the Trilobite beetle (Platerodrilus genus) look like regular net-winged beetles, but measure just 8-9 mm long.

Net-winged Beetle Characteristics Banded net-winged beetle Trilobite beetle
Length 10-15 mm 8-9 mm
Antennae Thick Thick
Wing covers Red/orange and black Red/orange and black

Net-winged beetles are classified under the:

  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Subphylum: Hexapoda
  • Class: Insecta

Physical Features and Identification

The Net-winged Beetle, specifically the Banded Net-winged Beetle (Calopteron discrepans), showcases distinct physical features. Here are some key characteristics:

  • Length: 10 to 15 mm
  • Colors: Orange and black
  • Elytra: Orange with black bands
  • Ridges: Elevated lengthwise and cross ridges

Adult Net-winged Beetles vary in size, with males typically being smaller than females. Their vibrant orange and black coloration serves as warning to predators that they are unpalatable.

The elytra, or wing covers, have an intricate pattern with median and terminal black bands on an orange background. These wing covers are also characterized by their elevated lengthwise ridges and cross ridges, a common feature in Lycid beetles ^(1^).

Here’s a comparison table of the features of Banded Net-winged Beetle:

Feature Description
Length 10 to 15 mm
Colors Orange and black
Elytra Orange with black bands
Ridges Elevated lengthwise ridges

These striking physical features make Net-winged Beetles easily identifiable and serve essential functions in their survival and reproduction.

The exoskeleton of the Banded Net-winged Beetle is soft-bodied, while their head is equipped with thick antennae, which play a crucial role in their sensory perception. In summary, the unique combination of color, elytra patterns, and ridges make the Banded Net-winged Beetle easy to identify and appreciate.

Habitat and Range

Net-winged beetles are found throughout North America, including Canada, the U.S., and Mexico. They occupy a variety of habitats, such as forests, grasslands, and wetlands.

Their preferred habitats include:

  • Trees: Beetles often dwell on tree trunks and branches.
  • Leaf litter: They seek refuge in decaying leaves on the forest floor.
  • Vegetation: Some species live among plants and shrubs in grasslands.

Net-winged beetles have a wide territorial reach, as shown in the territorial map [link to the map]. They are most active around sundown, where they can be seen flying in search of food or mates.

Some key characteristics of net-winged beetles include:

  • Relatively small size, usually less than 1 inch in length
  • Distinctive wing patterns with a network of raised veins
  • Nocturnal behavior, with increased activity around sundown

Comparing the range and habitat preferences of net-winged beetles to other beetle families:

Beetle Family Range Preferred Habitat
Net-winged beetles North America Trees, leaf litter, vegetation
Stag beetles North America, Europe Decaying wood, forested areas
Dung beetles Worldwide Animal waste, grasslands, forests

Diet and Feeding Habits

Banded net-winged beetles, scientifically known as Calopteron discrepans, mainly feed on two primary sources:

  • Nectar: An important food source for adults.
  • Pollen: Additionally consumed by adult beetles.

These beetles are often found on:

  • Flowers: Where they enjoy nectar and pollen.
  • Plants: During the larvae stage, they consume fungi and rotting plants.

Below is a comparison table illustrating the diet of adult and larval net-winged beetles:

Life Stage Food Source
Adult Nectar & Pollen
Larvae Fungi & Plants

Some features of the net-winged beetle’s diet include:

  • Attraction to flowers for food.
  • Consumption of plant-based materials.
  • Ability to survive on a variety of plant sources.

In summary, net-winged beetles have a diet primarily consisting of nectar, pollen, plants, and fungi, depending on their developmental stage. They are often found on flowers, where they can easily access their food sources.

Life Cycle

The life cycle of a net-winged beetle goes through complete metamorphosis, consisting of four stages: egg, larva, pupa, and adult1.

Egg Stage

  • The first stage in the beetle’s life cycle
  • Duration of 7 to 10 days1

Larva Stage

  • Second stage in the beetle’s life cycle
  • Features soft body and thick antennae2

Pupa Stage

  • Third stage before becoming an adult
  • Transformation from larva to adult happens here

Adult Stage

  • Final stage, where beetle has developed wings
  • Males are smaller than females3

Comparison Table

Stage Duration Characteristics
Egg 7 to 10 days First stage, beetle in egg form
Larva Varies Soft body, thick antennae
Pupa Varies Transformation to adult happens
Adult Until death Developed wings, can reproduce

Predators and Defense Mechanisms

Net-winged beetles face various predators such as Thalmor, wolf spiders, and orb-weaving spiders. To fend off these threats, these beetles employ several defense mechanisms.

  • Aposematic warning coloration: Net-winged beetles exhibit bright colors to warn predators of their unpalatable nature.
  • Chemical defenses: These beetles produce chemicals like lycidic acid and fatty acids1 to deter would-be attackers.

A key component of the net-winged beetle’s defenses is its mimicry complex. Some examples include resembling fireflies and soldier beetles2.

Here is a comparison table of some predators and defense mechanisms of net-winged beetles:

Predator Defense Mechanism
Thalmor Warning coloration
Wolf Spiders Chemical defense
Orb-weaving Spiders Mimicry complex

Overall, net-winged beetles have evolved effective strategies to avoid predation by combining their warning coloration, chemical defenses, and clever mimicry.

Interactions with Other Species

Net-winged beetles, particularly those in the genus Platerodrilus, have some interesting interactions with other species. One notable example is their relationship with fungi. These beetles feed on fungal spores and help disperse them throughout their environment source.

Some species, like Pyromorpha and Lycomorpha, have developed vibrant warning colors to deter predators source. The colors serve as a signal that they contain chemical defenses, such as noxious odors, to repel potential threats.

  • Features of Platerodrilus beetles:

    • Feed on fungal spores
    • Disperse fungi throughout their environment
  • Features of Pyromorpha and Lycomorpha beetles:

    • Vibrant warning colors
    • Chemical defenses like noxious odors

Beetles such as Platerodrilus have developed ways to mitigate risks from fungi. They actively remove fungal spores before grooming themselves to prevent infection source.

Some net-winged beetles, including Platerodrilus, are known to engage in mutualistic relationships. Their feeding on fungi can benefit both the beetle and the fungi, as the beetle gets a food source and the fungi get a means of dispersion source.

Feature Platerodrilus Pyromorpha & Lycomorpha
Interaction with fungi Feed on fungal spores Not applicable
Relation with predators Not applicable Chemical defenses
Mutualistic relationships Possible with fungi Not applicable

Overall, net-winged beetles are unique in their interactions with other species by engaging in mutualistic relationships and utilizing chemical defenses against predators.

Research and Scientific Studies

Net-winged beetles belong to the scientific name Calopteron. They comprise several species, including Calopteron terminale, Calopteron reticulatum, and Calopteron discrepans 1. These species exhibit distinct coloration and defensive abilities.

For instance, Calopteron discrepans adults are around 10 to 15 mm long and display orange elytra with black bands2. These beetles are known for their brilliant colors, which serve as a warning to predators of their noxious odors3.

Renowned entomologist Thomas Eisner has contributed significantly to research on these insects4. In his book “Secret Weapons: Defenses of Insects, Spiders, Scorpions, and Other Many-Legged Creatures,” Eisner explores the unconventional protective mechanisms employed by net-winged beetles5.

Here’s a comparison table of the three common net-winged beetle species:

Species Size Colors
Calopteron terminale 10-15 mm Orange and black
Calopteron reticulatum 10-15 mm Orange and black
Calopteron discrepans 10-15 mm Orange and black bands2

In conclusion, net-winged beetles are fascinating insects with their vibrant colors, intriguing defensive strategies, and varying species. Ongoing research, including work by Thomas Eisner, has provided valuable insight into their lives and natural history.

Orange/black mystery bug
Location: Radnor, Pennsylvania (suburban Philly)
August 16, 2011 7:07 am
I saw this insect sitting on my car this past week and don’t recall ever seeing it before. The body/wings are about 5/8” long and with the antennae it was just over 1 inch total length. I’ve so far not been able to get an ID on what it is.

Banded Net-Wing Beetle

Hi Orla,
This little beauty is a Banded Net-Wing Beetle,
Calopteron reticulatum.  It is a generally accepted theory that orange and black insects display aposomatic coloration to dissuade predators, either because they are dangerous, or poisonous, or don’t taste good.  The Banded Net-Wing Beetle is not dangerous or poisonous, and taste is relative.  It may be part of a complex mimicry system that includes some moths and some wasps.  The wasps sting, and insects that mimic them may benefit from the protection the wasps enjoy because of their stinging capacity.  This is speculative editorialization on the part of our staff, and not something we can cite.  You may turn to BugGuide for additional information on the Banded Net-Wing Beetle.

Net-Winged Beetle

Dear Hanri,
This is a Net-Winged Beetle in the family Lycidae, and though it resembles the individuals pictured on Biodiversity Explorer, it is definitely a different species.  According to Biodiversity Explorer:  “Adults are active by day and occur on various plants and grasses and also feed on nectar. The larvae live in decaying wood and possibly feed on fungi. The orange and black colouration is mimicked by various insects as these animals contain cantharadin and are distasteful to birds and other predators.”  Your individual looks exactly like the Hook Winged Net Winged Beetle,
Lycus melanurus, pictured on Blue Gnu, a species also pictured on iNaturalist.

Trilobite Beetle

Hi Brandon,
This unusual creature is known as a Trilobite Beetle,
Duliticola hoiseni, and we first posted an image of this interesting beetle back in 2006.  At that time Eric Eaton wrote in: “The firefly larva from Thailand is actually an ADULT female Demosis species of net-winged beetle (family Lycidae). They are known commonly as trilobite beetles.”  There is now more information online for this fascinating creature, including these great images on Animals, Animals, Animals.  There is a wealth of information but no images on Animal Diversity Web, including this physical description:  “Duliticola hoiseni is an exceedingly segmented creature with a very small head that retracts into the prothorax. The prothorax is a triangular segment that has two small tubercles protruding from the front of the segment near the area where the head extends. Two larger tubercles are near the back of the prothorax segment. The extendable head of the trilobite beetle has very small eyes which sit behind two-jointed antennae. The segment behind the prothorax, the mesothorax, is much wider than the first segment, with four large tear-drop shaped tubercles situated in the middle and a pair of smaller ones near the rear. The next segment, the metathorax, is much like the mesothorax, with the addition of a straight, swept back posterior edge. The nine-segmented abdomen is covered in cylindrical abdominal processes, which originate from the rear of each segment and angle back and upwards. Mature females are yellowish-white, whereas the males and immature females are generally a dark brown color with cinnamon colored processes. The average size of this insect is between 35 mm and 45 mm. (Lok, 2008)”

Hi Leslie and kids,
We really wish your photos of a Banded Net-Wing, Calopteron reticulatum, were clearer. Though it looks like a moth, this is actually a beetle in the family Lycidae. It is found in moist woods and meadows where it feeds on juices from decaying plant matter.

This fellow came to my ”bug fly-in” this morning. After searching around the internet I think I have an ID from bug guide. I believe it is an End Band Net-Wing Beetle (Calopteron terminale) I noticed you do not have one of these on your website. (Not exactly like this one anyway) I don’t think I ever saw one of these before today, but that was probably because I wasn’t looking. Thanks and have a great day.

End Band Netwing Beetle

Hi Richard,
Thank you so much for adding to our archives with this under-represented species, the End Band Netwing Beetle,
Calopteron terminale.  We were, however, disturbed that you indicated we had none in our archive, so we searched and found this old posting from 2008 of Mating End Band Netwing Beetles.  At the end of summer that year, we did a major site migration and an overhaul of the methods we had previously used to make postings.  Our awesome web master, Daniel, transferred the entire archives and set up a system for organizing various categories and subcategories, but much work remained.  Our categorizations got much more specific after that, but the older archives are still categorized in a more general way.  They are in disarray.  Because of your letter, we have identified significantly more Netwing Beetles from the archive than the seven postings that were in that subcategory this morning.  We should really allot more time to cleaning up our archives, but we spend so much time trying to post all of the fabulous new submissions we receive that we have, except in a few cases, left the archives in their jumbled form.  It is always best to try to use our search engine to locate items from our more disorganized early history.

Bug with orange and metallic blue wings
Dear Bugman,
I have another strange insect we can’t identify. My husband took this picture in Sept 2006 of this bug on the leaf of an iris. I tired to find this one on the web and did not have much luck. I figured with such beautiful and distinctive wings that it would be easy, but I don’t even what basic type of bug this is. Thank you for your help.
Peggi Wolfe
Natchez, MS

Hi Peggi,
Judging by the number of visible wings, there is a second End Band Netwing Beetle, Calopteron terminale, hidden behind the visible one. We can only deduce that they are in the process of mating, or attempting to mate. You shouldn’t feel badly that you couldn’t identify them, since Netwing Beetles resemble moths more than typical beetles.

Hi bugman, been a while since i sent you anything. I have went to Australia since my last submission.
What we have here is the Porrostoma rhipidium – Long nose Lycid Beetle. He is a very docile and somewhat curious critter. He crawled around on me while i took many shots.. then as I let him go, he landed beside of me and continued hanging around in the yard for another entire day.

Long-Nosed Lycid Beetle

Thanks so much for sending us this marvelous submission.  The Brisbane Insect Websitehas many excellent images of this species.  Members of the family Lycidae are commonly called Net-Winged Beetles and they are somewhat unusual in that they have soft elytra, unlike most beetles.  Now that winter is approaching in the northern hemisphere, we are expecting a surge in submissions from Australia if our typical annual cycle remains unchanged.

Not a Large Milkweed Bug – what is it
Hi … I think I may have found something new for you. Found this pair of bugs mating on a rock. Looked through your website and it comes closest to the Large Milkweed Bug (LMB). However, look carefully at the segmented antennae. After the base, there are 9 segments on these bugs, whereas the LMB has only 3. Also, the face is black, whereas the LMB’s face is orange. And the backs are somewhat like ‘corduroy’, whereas the LMB has an ‘X’ in the center. Lastly, the size is different. I believe LMB’s are about 1/2″ long, whereas the body of the larger one I captured was about 1″ long. What’s that bug?

Though they look mothlike, there are actually beetles.  Net-Winged Beetles are in the family Lycidae, and we are relatively certain your specimens are in the genus Lycus.  BugGuide has two similar looking species, and we are not certain if your beetles are Lycus arizonensis or Lycus fernandezi.  BugGuide also indicates that adults eat nectar and honeydew.

Neighbor found this insect on her patio. What looks like honeycomb is actually a doormat. To me, it looks like a Lepidoptera (moth) but I can’t see enough of the head to make out the antenna form. Also can’t see the wings on the metathorax. I would appreciate any help or suggestions that you can give me. In the meantime, I will continue to research the internet. Thank you.

Thank you for your prompt response. I continued looking and I now believe that it is a Net Winged beetle. If I had been able to see the head, the antennae would have pointed me to the Coleoptera rather than the Lepidoptera.
“Net-winged beetles (family Lycidae), any of some 2,800 species of soft-bodied, brightly coloured, predominately tropical beetles (insect order Coleoptera) whose wing covers, or elytra, are broader at the tip than at the base and are characterized by a raised network of lines, or veins. The adults feed either on plant juices or on other insects and can easily be seen as they fly slowly between plants or crawl on flowers . The bold colouring of orange and black or blue probably warns predators of their acidic, burning taste. Larvae feed on wet rotting wood and are often found in high numbers.”

Hi Don,
We apologize for the delay.  For some reason, there was a glitch in our email delivery and submissions were being delayed several days.  We agree that this is a Net Winged Beetle in the genus
Dictyoptera, and it is most likely the Golden Net Wing, Dictyoptera aurora.  Of the four species listed on BugGuide, only two are reported from Alabama, including the Golden Net Winged Beetle.  The other, Dictyoptera munda, is represented by a single mounted specimen on BugGuide, but the thorax lacks the dark markings.

Dear Judy,
This Net-Winged Beetle,
Caenia dimidiata, resembles a moth more than it does a typical beetle.  According to BugGuide, it “has comb-like antennae, and scutellum is black.”

Very cool! Thanks for the ID! It looked a lot like a firefly when it was in flight, which makes sense since they’re related. I appreciate the info.

Your letter to the bugman:  We found 3 of these hanging out on Douglas Fir limbs on a very chilly day recently (02/19/2019).  They reminded us a little of fireflies in the manner in which they opened their wings, but we thought that they couldn’t be. They have such strange shaped heads with what seems like very ornamental head gear.

Net-Winged Beetle and Unknown butterfly
Hi Bugman!
I spotted this Net-winged Beetle (Calopteron reticulatum) in my yard today! Once again, I was able to identify it using your site! I didn’t, however, see any photos of my Mystery Butterfly – thought maybe you could help to identify it? I followed this spastic little thing in my yard for an hour trying to get a good shot of it! I was lucky enough to get this one before it took off again, but was unsuccessful in getting a closed wing shot. The underside of its wings are white, and seemed to have a small black mark near the edge of the lower wing. We are in Southwest Missouri. Thanks for your help!
Kris L.

Net Winged Beetle Eastern Tailed Blue

Hi Kris,
You did well on the Net-Winged Beetle identification. Few people would have even guessed it was a beetle. The butterfly is a female Eastern Tailed Blue, Everes comyntas. The Western Tailed Blue would be our second guess as the two are difficult to distinguish, but we don’t believe the Western Tailed Blue ranges as far east as Missouri. The caterpillars feed on leguninous plants.

Dear Ryder,
Congratulations on recognizing that the Net Winged Beetle in the family Lycidae is actually a Beetle because it is frequently mistaken for a moth.  We suspect it might be the North American species
Calopteron reticulatum, the Banded Net Winged Beetle which is reported on BugGuide as being from Mexico as well.  Insects do not respect international borders.

Hi Daniel,
thank you for replying to my email, I’m so happy i know what it is now.

This is a Net-Winged Beetle in the family Lycidae, and according to BugGuide:  “Adults eat nectar and honeydew. Larvae: Despite anecdotal reports of carnivory, most, if not all, feed on myxomycetes or metabolic products of fungi.”  Though you may desire to keep this lovely beetle in captivity, we feel it would be better to release it back into the wild to fend for itself.  We are unable to provide a species identification at this time.

Dear David,
This is a Net-Winged Beetle in the family Lycidae, and according to Delta:  “Lycid adults are commonly seen flying at dusk and may be found in flowers or on foliage. Some adults may be nectar-feeders, but others probably do not feed at all. Larvae occur under bark or in leaf litter; they are liquid feeders, but there is little reliable information on their diet.”  According to BugGuide:  “Adults eat nectar and honeydew. Larvae: Despite anecdotal reports of carnivory, most, if not all, feed on myxomycetes or metabolic products of fungi.”  This beetle will not harm your orchids and the larvae might be living in the bark you use to cultivate the orchids.

Hi Teresa,
This is one of the Netwing Beetles in the family Lycidae. We believe it is the Golden Netwing Beetle, Dictyopterus aurora. According to BugGuide, it is found over much of North America in the spring. Eric Eaton has added this qualification: ” The golden netwing beetle is definitely in the Dictyopterus genus, but there are several species in the west, so I would hesitate to put a species name to it. Probably not the same one as is found in the eastern U.S. at any rate.”

Mystery larvae (or pupae?)
Wed, Nov 12, 2008 at 7:55 AM
I was visiting one of our local natural areas and I found these dense clusters of insects on the lower stems of several woody plants in a small area. They didn’t move at all when prodded. They were found in a mixed hardwood/pine woods with dense leaf litter on the ground. I haven’t done a lot of research on what these might be, but I’m wondering if this is some sort of beetle?

Netwing Beetle Larvae maybe
Beetle Larvae

Hi G.P.,
We believe these are Netwing Beetle Larvae in the family Lycidae. There is an image on BugGuide that looks quite close. We want to get an opinion from Eric Eaton on this curiosity.

Before you ask:
I suspect that the beetle larvae may be of the pleasing fungus beetle family Erotylidae rather than the net-wing beetles.  I could very well be wrong, of course….

Letter 43 – Netwing Beetle Larvae or maybe Fungus Beetle Larvae perhaps???


Herd of bug on tree trunk
I found this herd of bugs at the base of a small tree in Houston, Texas on August 17, 2008. They remind me of praying mantis eggs, but they’re smaller. What are they and what are they doing? Are they hurting my tree? I don’t know if it’s important, but there was this small fly on a blade of grass next to them. Thank you

Hi Sandra,
The detail on your photo is not clear enough to make out individuals, but we suspect these may be Netwing Beetle Larvae, family Lycidae. Luckily, you sent a detail image as well which supports our theory. See this photo of an individual on BugGuide to see if it matches what you have. Netwing Beetle Larvae eat fungus and fungus often grows at the base of trees. If these are Netwing Beetle Larvae, they are not harming your tree, but the tree may already be compromised if fungus is growing.

Comment: (08/17/2008)
I’m not sure, either. Probably one of the fungus beetles in the Erotylidae would be my guess. I have seen larvae of Gibbifer californicus in large numbers like this.

Newly Metamorphosed Net-Winged Beetle

Hi Tammy,
This is a Net-Winged Beetle.  Because of its engorged abdomen and the relatively small size of its wings, we believe it is a freshly metamorphosed individual.  The wings will increase in size and harden slightly so that the Net-Winged Beetle will be able to fly.  Net-Winged Beetles are frequently confused with moths.  We believe your individual is in the genus
Lycus based on photos and information posted to BugGuide.

  1. I have these in my yard as well. It is interesting that you mention mimicking wasps….when they land they pump their wing covers like wasps and hornets do

  2. Hello, I was also wondering about possible damage to crops. I found one or two in the beginning of the week and there are now at least a dozen scattered across my garden mostly on my squash plants. No matter where I look I cant find a definitive answer on whether or not they are beneficial.

    • Though we don’t know why your squash plants are attracting Banded Net-Wing Beetles, we can relay that on the genus page on BugGuide, it states: “adults take nectar; larvae prey on small arthropods under bark” which would imply that this is a beneficial species.

  3. I can’t believe that two clicks in, I found a picture of the bug that visited me last evening, the Banded Net-Winged Beetle. I played with him (or her) for a while and then put him on a hibiscus. He was very beautiful and friendly (-: I had never seen this insect before last night.
