Dung Beetle: All You Need to Know for a Fascinating Insight

Dung beetles are fascinating insects that play a crucial role in our ecosystem by removing and recycling animal feces. These underrated creatures can be found in various habitats, but they tend to avoid extremely cold or dry weather conditions source. With over 6,000 species worldwide, dung beetles exhibit unique behaviors and provide significant ecological benefits source.

These small yet powerful insects rely on feces for both their food and reproduction. The life cycle of a dung beetle involves laying eggs in the dung, which serves as a food source for larvae as they develop and eventually pupate source. Dung beetles come in a variety of shapes and sizes but are most commonly recognized as the beetles rolling dung balls, transferring them to their underground burrows.

Some outstanding benefits of dung beetles include:

  • Improving nutrient recycling and soil quality by burying dung and creating tunnels
  • Promoting soil aeration, which helps plant growth
  • Reducing harmful parasites and pathogens in the environment by consuming feces
  • Contributing to the control of pest populations, such as flies and gastrointestinal parasites.

Given their essential ecological functions, it is crucial to recognize and appreciate the role these tiny insects play in maintaining the delicate balance of our natural world.

What Are Dung Beetles

Classification and Diversity

Dung beetles are a group of insects under the family Scarabaeidae within the order Coleoptera, commonly known as scarab beetles. They are a large and diverse group with over 6,000 species found worldwide1.

Physical Characteristics

Dung beetles are typically oval, stout, and possess clubbed antennae with feathery segments2. They exhibit variations in size and color, but most species share these key features:

  • Body length ranging from 1/2 to 1 inch3
  • A metallic appearance with hues like blue-green, copper, or golden bronze3

Behavior and Roles

These remarkable insects have specific behaviors that revolve around the removal of animal feces for food and reproduction4. Here are some of their key roles:

  • Tunnelers: Collect dung from the surface and carry it underground to feed their young5
  • Rollers: Shape dung into balls and roll them away from the dung pile to bury and consume later2

Dung beetles are considered beneficial to the environment due to their ecological and economic advantages4:

  • Aiding in waste decomposition
  • Improving soil structure and nutrient cycling

Food Storage Underground burrows Rolled dung balls
Predominant Behavior Burrowing Rolling

Types of Dung Beetles

Rollers

Rollers are a type of dung beetle known for their unique behavior of rolling dung into balls. They primarily feed on animal feces and use the dung balls as both food and breeding ground. Examples of rollers include the well-known Scarabaeus sacer and the Gymnopleurus mopsus. Some key features of rollers are:

  • Roll dung into balls: Rollers shape the dung into balls that are easier to handle and transport.
  • Serve multiple purposes: The dung balls provide both food and a breeding ground for offspring.

Dwellers

Dwellers, also known as endocoprids, are dung beetles that live within or just below fresh dung piles. They feed and lay eggs within the dung, providing a safe environment for their young to develop. Examples of dwellers include Aphodius and Euoniticellus species. These beetles have the following characteristics:

  • Live within dung piles: Dwellers stay directly in their food source for easy access and protection.
  • Lay eggs in dung: This provides a safe environment for their offspring to hatch and develop.

Tunnelers

Tunnelers, or paracoprids, are dung beetles that dig tunnels underneath dung piles. They move dung into the tunnels and lay their eggs there, providing a protected space for their larva to grow. Examples of tunnelers include Onthophagus and Copris species. Some unique features of tunnelers are:

  • Dig tunnels below dung: This creates a more secure and protected environment for the beetles and their offspring.
  • Transport dung underground: Tunnelers move dung into the tunnels to use as a food source and breeding ground.

Comparison Table

Type Food Source Dwelling Location Example Species
Rollers Animal feces (dung) On the ground Scarabaeus sacer
Dwellers Animal feces (dung) Inside dung piles Aphodius species
Tunnelers Animal feces (dung) Below dung piles Onthophagus species—

Life Cycle and Reproduction

Brood Ball Formation

In dung beetles, the female forms a brood ball from dung to lay her eggs. She carefully shapes the ball, which often contains a single egg. Here are some key characteristics of brood ball formation:

  • Made of dung
  • Contains a single egg
  • Shaped by the female dung beetle

Larval Development

After the egg hatches, the larva feeds on the dung within the brood ball. This stage is crucial for their growth. Larvae are also referred to as grubs during this stage. Some key features of larval development include:

  • Feeding on dung within the brood ball
  • Transformation from larvae to grubs
  • Growth and development within the ball

Mating and Parental Care

Dung beetles mate in a fascinating way. When a male locates a female, he courts her using specific techniques, such as stroking his antennae and front legs quickly (source). Parental care in dung beetles varies among species. For example, some species don’t show any parental care, while others care for their offspring in different ways.

Pros and Cons of Parental Care in Dung Beetles

Pros Cons
Increased offspring survival Energy expenditure
Protection from predators Reduced mating opportunities

The life cycle and reproduction of dung beetles involve the formation of brood balls, larval development within these balls, and a unique mating process. Parental care differs across species, with both pros and cons to the level of care provided.

Feeding and Nutrition

Dung as a Food Source

Dung beetles primarily feed on the feces of herbivores and omnivores. Their strong sense of smell helps them locate fresh dung quickly. They form dung balls, which are essential for their diet and reproduction. For instance, the Aphodius badipes (‘big black beetle’)1 and Aphodius fimetarius (‘red backs’)2 are dung beetle species that utilize animal feces this way.

Other Sources of Nutrition

In addition to dung, some dung beetles also consume fungi3, decaying leaves, and plant matter. This makes them partially omnivorous. Here’s a brief comparison of their food sources:

Food Source Examples Benefits
Dung (Feces) Herbivore and omnivore feces Rich in nutrients
Fungi Mushrooms, molds Additional nutrients
Decaying Plant Matter Leaves, fruits Supplement to diet
  • Nutrition in Adults: Adult dung beetles gain most of their nutrition from poop.
  • Herbivores and Omnivores’ feces: Dung beetles prefer feces from herbivores and omnivores, as they are richer in nutrients.

Amazing Abilities

Strength and Carrying Capacity

Dung beetles possess incredible strength, able to pull 1,141 times their body weight1. This feat is akin to a human pulling six fully loaded double-decker buses1. These beetles can carry or roll balls of dung up to 10 times their weight2. They can even bury dung 250 times heavier than their own body mass in just a single night2.

Navigation Skills

Surprisingly, dung beetles have impressive navigation skills using celestial signals2. Diurnal species, for example, rely on the sun to maintain a straight course while rolling their dung balls2. These navigational abilities enable them to travel long distances, sometimes flying up to 30 miles in search of dung2.

Fighting and Defense Mechanisms

Dung beetles exhibit various fighting and defense mechanisms depending on their species. One prominent feature is their horns, which are often used in battles with other beetles for territory and access to resources3. Additionally, their strong sense of smell4 helps them locate and protect their food source. Some species also have the ability to fly2, which can be advantageous in escaping predators or reaching new feeding grounds quickly.

Comparison of Different Abilities:

Abilities Examples
Strength Pulling 1,141 times their body weight1
Carrying Capacity Rolling balls of dung up to 10 times their weight2
Navigation Using celestial signals to travel in straight lines2, flying up to 30 miles2
Defense Mechanisms Fighting with horns3, strong sense of smell4, flying2

Habitats and Adaptations

Forests

Dung beetles mainly live and work in various habitats, including forests. They have unique adaptations to feed on animal feces found in these areas. For instance, forest beetles often feed on fruits and invertebrates besides dung, providing diversification in their diet.

Deserts

In desert habitats, dung beetles adapt to the challenging environment by being active at night, avoiding the extreme heat. They are known to utilize dung from various animals, as well as decaying vegetation and carrion when necessary.

Agricultural Lands

Dung beetles can be found living in agricultural lands, where they play an essential role in disposing of animal waste. They benefit these ecosystems by:

  • Recycling nutrients back into the soil
  • Improving soil structure and aeration
  • Reducing pests such as flies and parasites

Comparison Table

Habitat Adaptations Diet
Forest Feed on fruits and invertebrates in addition to dung Fruits, invertebrates, dung
Desert Nocturnal activity to avoid extreme heat Decaying vegetation, carrion
Agricultural Efficient waste disposal and recycling Dung

These different habitats influence how dung beetles adapt their behaviors and diets, showcasing their versatility and ecological importance.

Ecological Importance

Impact on Soil and Plant Growth

Dung beetles play a significant role in improving soil quality. They help in:

  • Nutrient cycling: By breaking down dung, they release essential nutrients back into the soil, such as nitrogen and phosphorus.

  • Soil aeration: Their tunneling activities allow for better water penetration and air circulation, promoting healthy plant growth.

Some American dung beetle species can even tame livestock waste, making it less harmful for the environment.

Seed Dispersal and Fertilization

Dung beetles contribute to seed dispersal, as they bury and move seeds found within dung. This leads to increased plant diversity and improved seedling emergence. Additionally, the action of burying dung with seeds provides fertilization, promoting a healthy plant growth in the surrounding areas.

Pest Control

Some dung beetle species prey upon harmful pests and act as a natural control agent for flies, parasites, and pathogens. By reducing these pest populations, dung beetles protect livestock and mitigate the spread of diseases that could potentially harm both animals and humans.

Feature Impact on Environment
Nutrient cycling Enriches soil
Soil aeration Promotes plant growth
Seed dispersal Increases plant diversity
Fertilization Enhances plant growth
Pest control Reduces disease spread

Dung Beetles in Culture and Symbolism

Ancient Egyptian Symbolism

Dung beetles, specifically the scarab beetle, held great significance in Ancient Egyptian culture. They were symbols of renewal and rebirth. Egyptians observed that dung beetles rolled dung into balls, and from these balls, new beetles emerged. They related this process to the sun god Ra, who rolled the sun across the sky.

Modern Representations

Dung beetles still hold cultural value today. A folktale from Sudan tells the story of a dung beetle who fell in love with the moon. The moon agreed to marry the beetle if it cleared all the dung from the earth.

Pros:

  • Dung beetles are associated with positive concepts like renewal, rebirth, and light
  • Stories about the beetles can be both educational and entertaining

Cons:

  • Some people might not appreciate the symbolism due to the beetles’ association with dung
Ancient Egyptian Symbolism Modern Representations

Scarab Beetle Grub

Dear Curious and Curiouser,
This insect larva is more than just “grub-like”.  It really is a Grub, the acceptable name for the larva of a Scarab Beetle, though other beetle larvae and insect larvae are also called Grubs.  You did not indicate exactly where it was found.  Many large Scarab Beetle Grubs are found in rotting wood since that is their food source.  Other Scarab Grubs, notably those of June Beetles, are frequently found while digging because they feed on roots.  Other Scarab Grubs are commonly found in compost piles.  We will be postdating your identification request to go live later in the week since we will be away from the office for a short time and we like having new posts on our site on a daily basis.

When we originally created that posting, we misidentified this Fruit Chafer,
Chlorobapta frontalis, as a Green Fiddler Beetle, but we were corrected by Karl.  Karl always provides links with his comments, and we can’t help but to wonder if the links have been broken in the intervening years.  There is a photo on iNaturalist and a link from there to this lovely FlickR image.  Project Noah has the correct scientific name, but interestingly calls it the common name Fiddler Beetle, which is generally used to describe Eupoecila australasiae.

Letter 7 – Scarab Beetle from Ethiopia: Pachnoda stehelini

 

Green and yellow beetle in Ethiopia
Location: Addis Ababa, Ethiopia
October 27, 2010 12:28 pm
Hi Mr Bugman – I am writing to ask your assistance in identifying a green and yellow beetle. The first flew into my house a couple of weeks ago in a , and the second after I moved to the fifth floor of an apartment block at the top of a hill in the city of Addis Ababa. They have both since left my home.
I named the first one Marius, and the second Julius (Te-See-Zar is Amharic language word for beetle). I would like to know what they eat/drink and their sleeping patterns (hibernation etc…) so I can make a comfortable home for them if they return.
They are the only two of this kind of beetle I have ever seen, so it seems a strange co-incidence that they both came to my home, were not able to fly away, seeming sluggish in their efforts, and after a couple of days of rest, vanished without a trace.
Thanks in advance for any assistance you can give me.
Signature: Billy Moon

Scarab Beetle: Pachnoda stehelini

Hi Billy,
Your beetle is one of the members of the large family Scarabaeidae, the Scarab Beetles.  It somewhat resembles the Green June Beetle or Figeater from North America, and we are guessing it is probably in the same subfamily, Cetoniinae, the Fruit and Flower Chafers.  We are guessing, that like many of its relatives, it will feed upon ripe fruit.  Next time try a banana or a peach.  Most Scarabs do not hibernate, but they will live for a few months as adults.  We believe your specimen looks very similar to
Pachnoda stehelini which we found on the Cetonidae Online Insect Museum website run by Benjamin Harink.  We then found some photos of living specimens on Goliathus.com.  There are also very nice images of it on Beetlespace.

Thank you very much for your reply. I have looked at the links you sent me. It is all very interesting. I will try a banana, or maybe some flower pollen next time.
Cheers

Letter 8 – Scarab Beetle Larva

 

Caterpillar ?Cicada larvae
Location: Michigan

I found this caterpillar in the garden on a sunny day in May in Michigan. It was very fast and before I got my camera it disapeared. When I located it, it had burrowed head first into the leaf litter on top of the soil. It had some bristles near the head. Looks like a cicada larva to me but the pictures I saw looked different.

Scarab Beetle Larva

Hi Linda,
This is the larva of a Scarab Beetle and it is commonly called a Grub.  Though we are uncertain of the exact species, we suspect it might be the larva of a Green June Beetle,
Cotinis nitida, which you can find pictured on BugGuide.

Thank you for the identification. It certainly does look like the one in BugGuide. I forgot to mention the size, it was large, at least 3 inches. My bug book shows the Green June Beetle larvae at 2 inches. I love your site and have it bookmarked. Thanks again, Linda

NOT Green Fiddler Beetle, rather Chlorobapta frontalis

Dear Melissa,
We believe at least one of your beetles is a Green Fiddler Beetle,
Eupoecila australasiae, which is a highly variable species.  In some individuals, the markings are green and in others they are yellow.  There is also some variation in the degree of the markings.  Your individual does not appear to have any markings on the pronotum, the foremost part of the thorax, and this is a characteristic we have not found in other images posted online.  The Brisbane Insect Website has some nice images of a yellow marked individual.  Oz Animals has an image of a yellow marked individual with significantly different markings than your individual.  Climate Watch indicates that they have dark brown or black legs, and one of your beetles has distinctly yellow legs.  You never sent an image of the dorsal surface of the second beetle you found, so we are curious what it looks like.  We wonder perhaps if this is a similar but less well documented member of the same genus.  Our searching did turn up another species in the genus, Eupoecila inscripta, which is pictured on FlickR, but it is a very different beetle.  We will tag this posting as a Mystery since we are uncertain if both beetles represent the same species.  Perhaps one of our more knowledgeable readers will be able to assist.

Scarab Beetle

Correction courtesy of Karl
Hi Daniel and Melissa:
The beetles in the posted images closely resemble Chlorobapta frontalis (Scarabaeidae: Cetoniinae). Melissa’s image does show a greenish margin around the front of the pronotum, although it is difficult to make out, but other markings on the rest of the dorsal surface are slightly different. The underside looks quite similar. The differences could be due variability in the species, or this may be a related species. There is one other Chlorobapta species in NSW, C. besti, but I was unable to find any images or descriptions. I can’t be certain about the species, but I believe that Chlorobapta is probably the correct genus. Regards. Karl

Dear Nature Dad,
We positively love that you gave us such nice differing views of your Rainbow Scarab.  Your beetle is a male as evidenced by his horn.  We hope you won’t think less of this beauty when you learn he is a Dung Beetle.  Dung Beetles mate and work in pairs to provide for the brood.  The roll excretia into a ball and roll it to the pre-dug burrow where they bury the ball of dung and lay an egg.  The pair divide the labor in the raising of the brood, a rarity in the insect world.  Daniel has written extensively on the family structure of mated Dung Beetles in his book, The Curious World of Bugs.

Hello Bugman. I found this weird looking beetle in my dog’s water bowl and I promptly brought it into the house so that I could Google it. After not finding it, I remembered your site (which I’ve been to a couple times before) and searched through the pages of beetles but I haven’t found it yet. Its about the same size as a quarter (as the picture shows) and is a metallic green color with metallic copper color on the carapace (?). It sports a single curved horn on its head. Sorry about the quality of the pictures, its been gloomy and wet all day.

hi Clay,
Your beetle is type of Dung Beetle commonly called a Rainbow Scarab, Phanaeus difformis. it is related to the similar looking, more common Rainbow Scarab, Phaneas vindex. BugGuide has a nice graphic that shows how to distinguish the two species based on the shape of pronotum.

Letter 21 – Rainbow Scarab Road Kill

 

Squished at 55 mph
Hi Bugaholics!
I was driving home from work the other day, and a breathtakingly beautiful beetle hit my windshield. I thought I’d been hit by a rock! The poor critter dropped into the area where the windshield wipers attach, and bedazzled me for the rest of the ride home. Unfortunately, he/she was a bit … um … disassembled. I tried to put various parts basically back into place without much luck. Surely this is a good specimen for the carnage section. So, what the heck kind of beetle is it? Wildlife has always interested me, and I have always been fascinated by bugs; but I’ve never seen this type before.

Your letter to the bugman:  I often see dung beetles drowning in my swimming pool-not sure why they wind up in there so often. Last Dec 31 I netted four of them in a few minutes and set them on a wall to dry out and take photos before they wandered away. One was gone before I could get back with the camera. I love how their shells vary- one had a beautiful long curving horn and side spikes on the shield. I wonder if that’s a variation due to age or gender or is it just that some beetles get lucky in the shell genetic lottery?

Rainbow Scarabs

Dear Marian,
Your image of rescued Rainbow Scarabs, a type of Dung Beetle, is awesome, as is the rescue story.  We are tagging this posting with the Bug Humanitarian Award.  Male Rainbow Scarabs have the horn, but there is some genetic lottery involved as well.  According to BugGuide:  “Pronotum of ‘major’ male has sharp posterior angles.  Major males, depicted, are easier to differentiate than minor males (w/ short horns) and females (w/ very short horns).”

Letter 24 – Scarab Beetle

 

carrizo plain beetle
Hi, I was visiting the Carrizo Plain east of Atascadero yesterday. About 5:30 pm these beetles started to get active. they seem to like to eat flowers. This flower is Thistle sage. I was at the plain a couple of years ago and right on schedule, the fiddle neck flowers were suddenly alive with hungry beetles munching flowers. The beetle is about 1/2 inch long or a bit more. Quite handsome I think. The notable thing I see, which may be distinctive, is a hairy fringe bordering the outer wings. Well, that’s how it looks, but probably the fringe is part of the inner wings. Without disturbing it, it was hard to tell. I don’t collect insects anymore since the dermistids got ahead of me at some point. It’s “catch, observe, release” now. Thanks for your great site. I used it last summer to ID the long horned alder borers I found crawling on a -you guessed it- freshly painted wall. I couldn’t resist poking them to see if they would hiss. Yes. Just like the Eucalyptus long horned borers do! Let me know when you find out. thanks
Sylva B. Los Angeles, CA

Hi Sylva,
This Scarab Beetle is Paracotalpa ursina and we cannot locate a common name. Interestingly, there is a photo posted to BugGuide of the species from 2006 and it is also in Carrizo Plains and it is also on thistle sage. Also of interest to us is that our friend and neighbor Clare Marter-Kenyon just mentioned seeing Thistle Sage for the first time.

Hi Daniel,
thanks. I am your neighbor, as I live on North Avenue 51, near Oxy.. I know Clare. It’s always fun to learn a new plant. I’ll send you a couple of photos of thistle sage from a 2 years ago, on the plain. Beautiful. Also, I have a photo for the bug love category. Thanks again for such quick response. Knowing the species, thanks to you, I found out that the beetle emerges from holes in the ground. Probably always in the evening when temp & wind die down. Type specimin at Harvard looks like it is covered with golden fur!!!

Location: Garden, Western Wisconsin

Dear bugman,
This is a new beetle I haven’t see before that ate its way through one of my tomatoes leaving behind a canyon in its wake. It’s the only one I’ve ever seen, and I can’t seem to find it any where online. It seems similar to the common June beetles, but the colors are much more vibrant and it has a healthy amount of hair underneath the shell and on top of its head. It is almost as wide as it is long with misshapen spots and stripes on the shell. I have not known June beetles to eat fruits so this is rather puzzling. Maybe a type of Japanese beetle?
Signature: Derek

Scarab Beetle
Possibly Bumble Flower Beetle

Hi Derek,
June Beetles and Japanese Beetles are both Scarab Beetles in the family Scarabaeidae, and the tomato eater in your image is also a Scarab Beetle, but it is neither a June Beetle nor a Japanese Beetle.  This is not the ideal image for identification as it does not show the entire beetle.  It might be a Bumble Flower Beetle,
Euphoria inda, which is pictured on BugGuide.  According to BugGuide:  “Adults visit flowers for pollen and/or nectar. Sometimes damage flowers. Also takes rotting fruit, corn, sap, other plant juices.”

Scarab Beetle

Dear Camille,
We will post your image of a male Scarab (note the antennae) and attempt to determine a genus and species identification for you.  Perhaps Cesar Crash from Insetologia will recognize this Scarab Beetle.  We looked at the genus
Chrysina on the Generic Guide to New World Scarab Beetles and no pictured individuals have a scutellum shaped like the one on your individual (see BugGuide where it states: “The scutellum typically forms a small posteriorly-pointing triangle at the base of the folded wings”), so we are not convinced that genus is correct.  This image of Calomacraspis haroldi on the Generic Guide to New World Scarab Beetles has a scutellum shaped like your individual.  Following that lead regarding the subtribe Anticheirina, we believe your Scarab might be Dorysthetus taeniata, which is pictured on the Generic Guide to New World Scarab Beetles.

Thank you so much Daniel! You are right about the shape/size of the scutellum. I noticed it but didn’t know what it was called or how to search for that difference. You are probably right about the genus Dorysthetus, but I’m not so sure about the species of Dorysthetus taeniata (at least compared with the photos I can find online). There is a lot of green edging on the scutellum as well as the insect’s nose area and eyes. Also, you can’t see it as well in this photo, but there are 4 light-colored spots along the very back sides. This is close enough for my labeling purposes although if you find out more, I would love to know for sure.
Thanks again!

We are not familiar with this genus of Scarab Beetles, but since it is in the subfamily Dynastinae, the Rhinoceros Beetles, we suspect this is a female since most males in this subfamily have fantastic horns.  Females present an additional identification challenge as they are often quite similar looking.  Perhaps one of our readers will be able to provide additional information.  We get so few submissions from Serbia.

Thank you for your reply. In the meantime I found out what species it is. Someone from iNaturalist who is also from Serbia said that there is actually only one species in Serbia which is Pentodon idiota.

Letter 43 – Scarab Beetle Head Beads in Ecuadorean Shuar Necklace

 

October 4, 2010
Dear Bug Man,
I’m happy to respond to your inquiry about the Giant Metallic Ceiba Borer and how it’s elytra is used in Shuar jewelry.

Although it is true that I spent several weeks in a remote Shuar village in Ecuador, I am not an expert on the beetles of the Amazon.  I can, however, attest to the great variety and quantity of bugs and beetles in the area, as well as the Shuar’s use of beetles to make decorative ornaments.

I was in Ecuador to make a documentary about headhunting– a complex ritual that had been outlawed many years before I visited the Amazon (although many of the elders were able to clearly describe the practice from memory).  The morning I took leave of the village, I traded my rain jacket and rubber boots for several wonderful handmade objects from local villagers, including three beautiful necklaces.

I am attaching a close view of one of the necklaces, which is made of beetle shells, as well as various seeds, bones and claws.  I’m not sure if these are the same beetles you are researching, but I thought the necklace might be of interest to your readers.

Shuar Necklace with Beetle Heads

Regarding Shuar food, I didn’t intentionally eat any beetles during my time in the Amazon jungle, but I did swallow a few bugs accidentally.  I also found many large beetles in my sleeping bag before I learned that I should keep it in a giant plastic bag until I was ready for bed.  Finally, I had part of an Amazonian bug (unidentified) removed from my ear a few weeks after I returned from my trip.

I didn’t eat Sunday dinner in Ecuador, but I enjoyed a number of festive communal meals that I believe served a similar function — to join in celebration of friends and family through a good meal.  The Shuar are extremely hospitable and prepared many wonderful dishes for the crew.  Our most delicious and memorable meal consisted of guinea pig steamed in large, fragrant leaves in the ashes of a fire pit.  Some of the more squeamish members of our team preferred to refer to the meat as “chicken”, despite the fact that there was a hut that housed at least thirty guinea pigs near the kitchen facilities.  We also drank chicha, a highly viscous drink made of fermented yucca.  To make chicha, the women of the village collect the yucca root, chew pieces of the yucca until it has the consistency of a fibrous paste and then spit it into large buckets.  The saliva begins the fermentation process that creates the alcohol content of chicha.  It is still used as a ceremonial drink to welcome visitors.  Chica tastes vaguely like beer and is rather pleasant if you don’t mind the fact that it’s two main ingredients are yucca and human saliva.  After a few days in the Amazon, I liked drinking chicha.

Sunday dinner or not, I enjoyed good food, good drink (at least drink with alcohol content) and good company while visiting the Shuar– that says “Sunday Dinner” to me!

Dear Susan Lutz,
Thank you so much for your response to our query.  The beetle parts on your lovely necklace appear to be the heads of Scarab Beetles, though we are not certain of the species.  Perhaps one of our readers will be able to contribute an identification.  There are several metallic green species in North America, including the Emerald Euphoria pictured on BugGuide and the Figeater from our own archives.  Though you were unable to provide any additional information on the Giant Metallic Ceiba Borer, we are certain our readership will be enthralled with your personal account of your Amazon exploits as well as the artifact you have illustrating the decorative use of insects by the indigenous people of the Amazon.

Karl provides an identification
Hi Daniel and Allen:
Your beetle is probably Ancognatha sp., specifically Ancognatha vulgaris (Scarabaeidae: Dynastinae). As a group, beetles in the subfamily Dynastinae are often referred to as Rhinoceros Beetles because of characteristic horns worn by the males of most species. This species is appears atypical in that respect, based on a photo of both sexes posted on the Perou-Insectes site. Regarding your inquiry about museums posting digital photos of their insect collections, there are a few but they tend to be very specific regionally, taxonomically or both. Less focussed online databases are usually rather sparse but sometimes you get lucky. For example, click on the image at: the Pictorial beetle collection of the Royal Belgian Institute of Natural Sciences (Mal, N., Drumont, A., Kerkhof, S. & P. Grootaert, 2012). Regards. Karl

Unknown South African Scarab Beetle

Dear Peter,
Some parts of the world, like Australia, Great Britain and North America have numerous internet resources for insect identification, while places like South Africa have a dearth of internet resources for insects, which is ironic as there are so many magnificent African species that are sold as mounted specimens.  Though our research on this Scarab Beetle has drawn a blank, we did find an Field Guide to Insects of South Africa that you might consider purchasing if you have other questions about the natural world in South Africa.  Sadly, our limited office space does not allow us the luxury of a comprehensive library for guide books for insects from around the world, and we must limit our research to the internet.  All we can offer at the moment is that this is a Scarab Beetle.  We are not sure of the identity of the other romantic couple in your photograph, though they appear to be Carrion Beetles.
Shortly after posting, we did one last ditch effort and we believe this may be a Flower Scarab in the genus
Leucocelis, based on photos posted to the Beetles of Africa website.  A photo of Leucocelis haemorrhoidalis from the Flower Beetles website looks very close.

  1. When these scarabs began to show up in our community garden they went after grapes and tomaoes, enmass. Some months after they were gone, while tirning over some composite soil, I unearthed some large grubs. They epwere about two inches long and almos 1/4″ wide and cream colored. Would have been great fish bait for someone. All years I’ve gardened never saw these things show up until the scarabs appeared. Just this last year during winter inunearthed one in my balcony compost pot. And being in different area these scarabs showed up here as well for about 3 months. I believe these grubs are scarab beetle larva. What else? And what say you?

  2. When I worked as a correctional officer I had 1 incarcerated individual throw in the shower stall with another incarcerated individual and that poor chap ran out of the shower screaming about something removing a very important part of his anatomy! It was an extremely large light tan insect that had 2 pinchers on the front of it. It was a good 3 inches long and not a slim bug. This was in New Hampshire and I have never seen another. Just curious and I do realize I may not have given you much to go on. The end of the story is that the chap that threw it in the shower had to remove it and the other guy was not hurt. Extremely funny and thankfully no one got hurt.

  3. Hello,
    I am just curious if it is normal that I found these in my backyard in Kansas, USA?
    to look it up and running across your site(which is incredible btw), I found it funny that I had no clue what to search so I looked up bug in dirt that looks like a shrimp?? lol
    anywho, NEVER seen anything like it, but I am also new to this area- originally from Oregon in the Willamette Valley and I have yet to become accustomed to many of the insects(NOT TO MENTION THEIR SIZE AND SHEER VOLUME OF ALL OF THEM) and I am mostly wondering if I can feed them and other cridders I have been catching in my yard, to my ornate box turtle[michelangelo] or my great plains toad[squeeks]? If you know, I mean, and/or maybe you can point me in a direction to gain more knowledge on the subject(s)? I have been feeding them all kinds of bugs I don’t know but I am concerned I will give them a bug that might make them sick… or worse?
    Thank you in advance!
