The Figeater Beetle, scientifically known as Cotinis mutabilis, is a fascinating insect with a fondness for figs. This beetle emerges from the ground and is commonly found during warmer months in search of ripe fruit. The diet of the fig eater includes figs, grapes, tomatoes, peaches, and plums which means that they are attracted to various over-ripe fruits.
Figeater Beetles are often seen flying around gardens in search of their next meal. It is important for gardeners and fruit enthusiasts to be aware of the presence of these beetles, as they can potentially damage fruit crops. Its large, green, and shiny appearance makes it easily identifiable among other insects, helping in its quick spotting by those vigilant of their gardens.
In this article, we will explore everything you need to know about the Figeater Beetle, from its life cycle to its behavior and impact on agriculture. You’ll also find information on how to manage these beetles in your garden to protect your fruit trees and enjoy a fruitful harvest. Stay tuned for a thorough understanding of this unique creature!
Figeater Beetle Overview
Classification and Appearance
The Figeater Beetle, scientifically known as Cotinis mutabilis, is a member of the family Scarabaeidae and subfamily Cetoniinae. Also known as the Green Fig Beetle or Green Fruit Beetle, this particular species of Scarab Beetle is known for its iridescent green color which can sometimes have hints of brown in its wing covers.
- Iridescent green color
- Part of the Scarabaeidae family
- Belongs to the Cetoniinae subfamily
Range and Habitat
Figeater Beetles are primarily found in the southwestern United States, with some overlap in the range of other beetles like the June Beetle, which is more common in the eastern US. These beetles typically emerge from the ground and are drawn to over-ripe fruit such as figs, grapes, tomatoes, peaches, and plums.
- Southwestern United States
- Overlaps with June Beetle range
- Attracted to over-ripe fruits
- Examples of fruits: figs, grapes, tomatoes, peaches, plums
|Feature||Figeater Beetle||June Beetle|
|Range||Southwestern US||Eastern US|
|Habitat||Over-ripe fruits||Decaying vegetation|
|Color||Iridescent green||Brown or black|
|Family and Subfamily||Scarabaeidae; Cetoniinae||Scarabaeidae; Melolonthinae|
Life Cycle and Behavior
From Eggs to Larvae
Figeater beetles begin their life cycle as eggs, often laid near a food source. The eggs hatch into larvae called crawly backs due to their distinctive movement. Some key characteristics of Figeater beetle larvae include:
- Creamy white color
- Composed of 4 body stages (instars)
These larvae feed on decaying plant material, helping with organic matter breakdown.
At the end of the larval stage, Figeater beetles prepare for pupation. During this time, they create a protective cell within the soil. They usually pupate for 7 to 10 days, before emerging as adults.
Adult Figeater beetles typically exhibit a metallic green or blue color and large legs. At this stage, they change their feeding habits to focus on ripe fruits like figs. Pros and cons of adult Figeater beetles are listed below:
- Help with pollination
- Aid in organic matter decomposition
- Can damage ripe fruits
- Might be considered a nuisance in gardens
As the Figeater beetle life cycle continues, they contribute to the ecosystem in various ways, both beneficial and destructive.
Diet and Interaction with Plants
Common Food Sources
Figeater beetles, also known as green June beetles, are attracted to a variety of sweet food sources. Some of the favored food sources include:
- Figs: These beetles are particularly drawn to ripe figs, which provide them with essential nutrients.
- Fruit trees: Figeater beetles may feed on several fruit trees, consuming fruits like peaches, plums, and grapes.
- Berries: These insects are also known to consume various berries, which serve as a staple in their diet.
- Nectar: Flower chafers like the figeater beetle may also feed on the nectar from desert trees.
Figeater beetles are also known to elope, searching for food like decomposing organic matter found in compost and mulch.
Impact on Gardens and Orchards
Figeater beetles can pose a threat to gardens, consuming petals and flowers from various plants. When the insects feed on tomatoes, for instance, they may leave significant damage.
Pros of figeater beetles in gardens:
- Help in breaking down decomposing organic matter
Cons of figeater beetles in gardens:
- Feed on flower petals, potentially harming plants
- May damage crops like tomatoes
Figeater beetles can have a significant impact on fruit trees in orchards due to their affinity for sweet food. They may consume sap from various fruit trees, as well as the fruits themselves. This behavior can lead to reduced yields and damage to fruit.
Pros of figeater beetles in orchards:
- May contribute to the decomposition of organic matter in the soil
Cons of figeater beetles in orchards:
- Potential damage to fruit trees, causing reduced yields
- Consumption of sap may weaken the tree
These insects can be controlled using environmentally-friendly pesticides, although some may resort to manual removal.
|Impact||Damage to flower petals and crops like tomatoes||Damage to fruit trees and reduced yields|
|Control||Environmentally-friendly pesticides or manual removal||Environmentally-friendly pesticides or manual removal|
Identification and Similar Species
The Figeater Beetle, also known as the green fruit beetle, is a member of the scarab family. Here are its distinctive features:
- Adult beetles are quite large, measuring between 3/4 to 1-1/3 inches long.
- Their coloration is mainly metallic green with brown or tan along the outside margins of their wing covers (elytra).
- They have six legs and a semi-glossy green appearance.
Figeater Beetle vs. Japanese Beetle
The Figeater Beetle (Cotinis nitida) is often mistaken for the Japanese Beetle (Popillia japonica). Here are some comparisons to help differentiate between the two:
- Size: Figeater beetles are larger than Japanese beetles.
- Color: While both have metallic green coloration, the Japanese beetle has copper-brown wing covers, compared to the brown or tan margins on Figeater beetle’s elytra.
|Feature||Figeater Beetle||Japanese Beetle|
|Size||3/4 to 1-1/3 inches||Smaller|
|Color||Metallic green with brown/tan margins||Metallic green with copper-brown wing covers|
Figeater Beetle vs. Green June Beetle
Another species that can be confused with Figeater Beetle is the Green June Beetle (Cotinis mutabilis). However, there are some differences between them:
- Geographic range: The Figeater beetle is more common in the southeastern United States, while the Green June beetle is found in the western parts of the country.
- Physical appearance: The Green June beetle has a more glossy appearance, while the Figeater beetle is semi-glossy.
- Coloration: Although both have metallic green coloration, the Green June beetle lacks the brown or tan margins on its elytra.
In summary, the Figeater Beetle is a metallic green scarab beetle with distinctive brown or tan margins on its wing covers. It’s essential to differentiate them from similar species like the Japanese Beetle and Green June Beetle, which have differences in size, color, and geographic distribution.
Preventing and Managing Infestations
Natural Predators and Control Methods
Figeater beetles are known for their damage to home gardens and overripe fruits, as well as their loud buzzing noise when flying. They tend to feed on nectar, fruit, and organic matter in the soil. Birds are known to be natural predators of these beetles. One effective way to control their population in your garden is to encourage bird presence.
Chickens are a perfect example of a natural predator that can help manage figeater beetles populations. They can feed on both the adult beetles and the beetle larvae in the soil. When cultivating your garden:
- Add a bird feeder or birdbath
- Provide habitats or shelters for birds
Another effective method to control figeater beetles is by exposure of larvae to nematodes, which are beneficial microorganisms that prey upon beetle larvae present in the soil.
Monitoring and Chemical Control
In managing figeater beetle infestations, monitoring is crucial, especially during the ripe fruit season. Inspect your garden regularly to spot any overripe fruits, which are highly attractive to these beetles:
- Remove and dispose of any overripe fruits immediately
- Employ tight-fitting screens around fruits to prevent beetles from reaching them
Chemical control should be a last resort to manage any persistent infestations. Some chemical control products can have adverse effects on the environment and non-target organisms. It is essential to consult a professional before using any chemical control methods.
Maintaining a healthy, balanced garden ecosystem and practicing good garden hygiene such as proper mulching and composting will also help prevent figeater beetles from becoming a persistent issue during the winter season when they are less active.
Figeater Beetles and Human Interaction
Harmlessness to Humans
- Figeater beetles are harmless to humans
- They do not bite, sting, or carry diseases
Figeater beetles are a common sight in gardens during the summer months, particularly in Mexico and California. Their buzzing sound can sometimes be mistaken for a bee, but rest assured, these beetles are harmless to humans. They neither bite nor sting and do not carry any diseases.
Impact on Fruit Crops
- Can cause damage to ripening fruits
- More prevalent in fig crops and orchards
Figeater beetles, also known as green fruit beetles, can have a negative impact on fruit crops. The adult beetles feed on ripe and overripe fruits, especially figs, leading to damage and reduced yields in orchards. They are highly attracted to the odors of manure and fermenting fruits, which can be found in agricultural areas. It’s worth noting that their life cycle is heavily influenced by irrigation practices, making it crucial to manage water resources properly during the growing season.
Comparison between Figeater Beetles and June Beetles
|Feature||Figeater Beetle||June Beetle|
|Size||Slightly larger||Slightly smaller|
|Habitat||Southwestern US, Mexico||Eastern US|
|Impact on Fruit Crops||Ripening fruits||Larvae feed on plant roots|
|Identification||Green color, scarab-like||Similar appearance|
|Attraction to Manure||Yes||No|
In conclusion, figeater beetles are harmless to humans but can cause damage to fruit crops during the summer months. Proper identification, management of irrigation practices, and an understanding of their life cycle can help minimize their impact on gardens and orchards.

Large Green Irridescent Beetle-looking bug
Location: San Fernando Valley CA
August 14, 2011 8:37 am
Hi ~ I recently moved to southern California (Winnetka CA), and these bugs are flying all over the place for the last few months (summer). I was terrified at first but someone told me they aren’t harmful. They are actually quite beautiful and they fly really slowly at times and you can catch them! I found this one dead on my driveway. What is it?
Signature: Best regards, Annette
Though it looks and sounds like a large bee while flying, you are correct that the Green Fruit Beetle, Cotinis mutabilis, is perfectly harmless, though they will eat your backyard fruit. If you have large numbers of them, you must have a nearby food source for either the adults of the larvae. Adults feed on peaches, figs and other summer fruits, and we love the common name Figeater. Larvae are found in compost piles and they are called Crawlybacks.
Daniel ~ Thank you so much!!
My neighbor has a LOT of fruit trees in his back yard. And he just brought over a pile of FIGS the other day J That explains it.
So glad I finally know what they are called.
Thanks again and have a wonderful week!

Irridescent Green & Gold trim bug
August 14, 2009
This bug came FLYING at me while on my patio on a sunny Los Angeles afternoon a couple of weeks ago. After chasing me for a bit on my patio (maybe it wanted a sip of my chardonnay?), it attached itself to my screen door, and just hung out (I went inside). Seemed to be missing it’s right leg.
Los Angeles, California
This is a Green Fruit Beetle, Cotinis mutabilis, also called a Figeater due to its fondness for eating figs. It is also fond of peaches. The Figeater is a common Los Angeles scarab beetle that is generally seen from late July through September.

Mettalic Green Beetle
September 3, 2009
I haven’t seen one of these in the Bay Area in 3 years. I’m wondering if it is local to California, it measured about 1in long. I was able to easily catch it by hand (very clumsy bug).
San Jose, CA
The Green Fruit Beetle or Figeater, Cotinus mutabilis, according to Charles Hogue in his book Insects of the Los Angeles Basin, was: “Originally native to Arizona and New Mexico, it gradually spread westward and became noticeable in the Los Angeles area after the 1960s.” Perhaps its range is spreading northward as well, possibly due to global warming, or perhaps by accidental introduction. Adults generally fly in Los Angeles during the hot final days of summer in August and September.

My husband the zoologist/science teacher and the rest of the science department are stumped. LOL. We need to call for the big guys!
For the past month the bug keeps flying at my sister when she sits outside. She lives in Fresno, CA and it is hot now. August weather has been over 100 degrees. 106 degrees for the past week. The bug is attracted to her and seems to fly at her anytime she is outside. We both have blond hair. She smokes a vapor pipe when she is outside. It is a big bug. It is probably the size of 1/2 of a humans palm. My sister said a dashound dog. LOL

I understand that you have stated that comments should be submitted via the Comment Form. However, since it does not have any way to attach images, I will be using this one. I apologize in advance if necessary.
The closely-related green fruit scarabs Cotinis mutabilis and C. nitida (they are NOT June beetles, despite the name “green June beetle”) often inspire great hatred and fear in the ignorant, due to their enormous size and “pest” status. However, many of the accusations are actually quite irrational. For the sake of brevity, I will only say that a few “cute” birds and squirrels are probably much more efficient fruit-eaters than a gardenful of Cotinis. They can probably be stopped easily with plastic bags tied around fruit, anyways.
The attached files are of my captive Cotinis mutabilis scarab. I found it in the swimming pool on the last day of July, and since its wings were damaged and useless it probably could not survive outdoors. Even though wild specimens always vanish by the end of September, this one refuses to kick the bucket. Cushy captive conditions have likely prolonged its life, but it is becoming slightly senile.
Like other members of its species, it is naturally quite tame and will allow itself to be hand-fed without any training. Unfortunately, it is not a very interesting “pet”. Like other members of its species, it will also enter an hours-long “food coma” when feeding on fruit. This can often last half a day, but when it is not busy feeding it is either trying to escape/fly (bugsincyberspace has informed me that this is not a sign of improper husbandry) or sleeping. This alone wouldn’t be too bad, but every few days its waste products stink up the jar and I have to perform maintenance.
However, a number of amusing incidents have occurred.
– Back when I had two rescued C. mutabilis males, they would take turns trying to inseminate each other. According to research articles online, this is actually a very common behavior in many insect species. Presumably, it is better to waste sperm than miss an opportunity! ( I know they were not females, since females do not actively seek out males.)
-It will also attempt to mate with non-beetles. If I handle it for too long, it will attempt to mate with my finger! Picture 2 shows the beetle trying to mate with its food dish. This is not an act of defecation, which looks very different. Perhaps the hard metallicity of the dish felt like another beetle.
However, I will warn readers that C. mutabilis and its close relative C. nitida are probably not well-suited to captivity. My captive specimen repeatedly attempts to fly despite its ruined wings, and wild individuals fly great distances and perform acrobatic feats in the air. Although I am not certain, keeping a non-flightless individual in captivity would likely cause it unnecessary distress. Even free-ranging one in the house does not work, as they always fly to a window and bang their heads against it constantly.

How you want your letter signed: Megan
Common names for the same insect can vary from location to location, and that gets even more complicated because insects do not respect international borders, with or without walls, and many times the national language changes across the border. To make things even more complicated, sometimes the same common name is used to describe more than one insect. That is why the scientific community uses the universal binomial system to identify creatures, but even that gets complicated because sometimes more than one scientific name is used to describe the same insect, but eventually one of those names supersedes the other. What’s That Bug? has always considered itself a pop culture insect site, so we frequently use common names in an effort to make us more friendly to the web browsing public which might find more scientific (and more reputable) sites off-putting because they are so scientific. The genus Cotinis is called, according to BugGuide, the Green June Beetles, so any member of the genus can be called by that common name. A common species found from Texas east, Cotinis nitida, is commonly called a Fig-Eater or Green June Beetle, according to BugGuide, and a common western species, that is found in California, is Cotinis mutabilis, and according to BugGuide, it is commonly called the Green Fig Beetle, the Green Fruit Beetle or the Figeater Beetle. Your species is the latter, so you may use any of the common names that specifically apply to the species, or the more general name Green June Beetle that applies to the entire genus. That is a very long-winded explanation that distills down to the answer that both names are correct for your species, though here at What’s That Bug?, we like to use Figeater for the western species, so you both are correct.

Your letter to the bugman: Hi,
A month or two ago these beetles were flying all over the place . Now they are mostly gone but I found this little guy the other day. I’m wondering what he is? I’m guessing fig eater or green June bug but I’m don’t know which and I’d like to know. Is it possible he’s different from the ones that were all over the place a few months ago? I’m trying to draw one and I’d like to label it correctly. Thanks!
How you want your letter signed: Natalie
Figeater and Green June Beetle are both acceptable common names for Cotinis nitida, according to BugGuide. Since common names are often regional, and might differ from place to place, and since the same common name might be used for different species, your most accurate label would be to use the scientific name.

I used your web site to find out the name of the bugs that recently arrived in our backyard. The Green Fruit Beetles don’t seem to mind sharing this peach . We live in Brea Ca. and this is the first time in ten years we have seen these beetles in our yard and on our peach tree. Thanks for the info .

How you want your letter signed: Chuck
Your beetle is a Figeater, a Green June Beetle that is quite common in California. The larvae, known as Crawlybacks, are often found in compost piles. The “bushy looking legs” you mentioned are of great interest to us. They look like phoretic Mites that often use large beetles like Sexton Beetles as transportation from location to location. We have an image in our archives of some eastern Green June Beetles with phoretic Mites.
I can grab one of the beetles for you? I closed the lid and they are still there. I usually turn the pile over quite often but have been away for travel: when I opened the lid, those guys were hanging out.
Thanks for the offer Chuck, but we have plenty of Figeaters in Southern California.

Subject: Life span of adult fig eater beetle
December 28, 2014 11:43 am
I rescued an adult fig eater beetle last July. He has damaged wings and is unable to fly. I left him out for a couple of days so nature could take its course but on the morning the gardeners were coming I found him hanging on to a blade of grass and couldn’t let him get chopped by the mower. Since then he has lived in a terrarium with grass, leaves, dirt, sticks and is eating grapes, figs and blueberries. He has occasional visits outside, where he crawls in the grass and climbs onto sticks and tries to fly But can’t manage to do so.
I am amazed he is still alive! How long will my house guest survive?
Since you did not provide us with an image, we are illustrating your query with an image of a Figeater from our archives. Since you have rescued this lovely Scarab from a premature death, we are tagging your letter with the Bug Humanitarian Award. Having averted the natural predators and food shortages that limit the life span of wild beetles, you have extended the life of the Figeater you rescued. We can’t imagine it living more than a year, so we speculate that your individual will expire by summer.
Thanks so much for the award! I am honored. I am also including a photo of the actual beetle (who is generally referred to as Bugman, although I am not sure of his/her gender). He is taking one of his walks on a hibiscus.
Please once again accept my humble thanks for the award! Glad to know that others support Bug Rescue 🙂
Hello again Kate,
Thanks so much for sending in your image of a Figeater with damaged elytra, the hard wing covers. We have formatted the image to illustrate the posting as the primary image and the image we found in our archives is now relegated to a secondary status.

The Student Union at the University of Arizona (Tucson) has been taken over by these little green guys. I’m not sure why they love the building so much, we don’t have any fig trees around here.
There are at least 2 every 10 feet as you walk through the breezeways and outdoor corridors of the building — dead or alive. This one wall is covered!
(sorry for the poor quality phone photos)
You are correct that these are Figeaters or Green Fruit Beetles, Cotinis mutabilis. According to BugGuide: “Adults feed on ripe fruit and sometimes sap.” The lack of figs in the area would not necessarily prevent such a healthy population of Figeaters. Though we expect that they do not prefer citrus, they are quite fond of peaches, plums and many other fruits that might be found nearby on your campus. If there is some type of organic compost or recently mulched landscaping, there might have been a large population of larvae thriving that has just recently emerged as adult beetles. Though the quality of the overview photograph is not ideal, it does nicely illustrate the large number of Figeaters present.
Thanks for your reply.
The week the figeaters appeared on the student union, lots of landscaping work was being done around the building, including bringing in some new sod and probably some new soil — that might have been where these guys came from!

Every year we witness a few Green June Beetles burying themselves in the mulch in our backyard (which, we learned from you, is to lay eggs). However, this was the first time the dogs got close to one & they acted like they were sprayed by it, both were sneezing & shaking their heads when they got within a foot or less of the rear of the beetle. I couldn’t smell anything, and I was pretty close, trying to shoot photos with my phone. Additional photos and longer version of the story:

Letter 19 – Sap Loving Insects: Mouning Cloak, Figeater and Beetle Larva
late summer bug party
Location: Silver City NM
September 1, 2011 6:08 pm
These pics are from last year, but the same thing is happening again. On my Navajo globe willow, the green beetles seem to be doing something that attracts the brown butterflies. Also, there’s a funny fuzzy little guy in there too. What is going on? What are these bugs?
In England, the butterfly known as the Mourning Cloak in America, is called the Camberwell Beauty. The metallic green beetle is a Figeater. The other creature is the larva of some soft winged beetle. The tree is oozing sap and that doesn’t seem like a good thing. The tree may have Borers. We hope you allow this exciting coeval feast to continue and closely observe the insects that come to the sap. Setting up night lights will attract moths, and many gorgeous Owlet Moths will be attracted to the luscious liquid diet. The Mourning Cloak will most likely begin hibernation as winter approaches. Your winters are likely quite mild, and the Mourning Cloak will not have to survive months of frozen conditions. This good meal of sugary sap would likely contribute to the survival of Mourning Cloaks in more hostile climates than that in Silver City, New Mexico.
Thanks for the prompt reply. I’ll set up lights this weekend.
