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.
Pupation
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.
Adulthood
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:
Pros:
- Help with pollination
- Aid in organic matter decomposition
Cons:
- 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
Gardens
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
Orchards
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.

Identification and Similar Species
Distinctive Features
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.
Bug Control Recommendation Tool
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.

Back home, in the Ozarks, we called these “June Bugs”. It was fun to tie a piece of thread to a hind leg and let them fly around or catch a jar full of them just for fun or fish with. That was entertainment!
I recently moved to Orange County, CA from the midwest and your pictures and description of this beetle was perfect! A rather large one flew into my garage today, and I thought it was the largest bee alive by the way it was flying, until the sun caught it and I saw the green/iridescent coloring. My son was able to direct it out of the garage with a broom easily, as it awkwardly flew around. A small humming bird had been by the garage door as this beetle entered and their wing spans were almost equal at a glance. This was the largest scarab shaped beetle I have ever seen, but not knowing what exactly it was there was no way I was batting it down for a measurement!
Thank you for a species name and more specific information so I know more about this native “bug” than I did before! =)

I too moved to CA from the Midwest, happy to leave the mosquitoes until this beetle freaked me out! Thankful for the explanation and hopeful that I now can calm down when I see, or rather hear them. 🙂
Glad to know what these flying fortresses are but don’t understand why my backyard and lanai are full of them! I live in an area of Cape Coral, FL that has no fruit trees whatsoever and haven’t seen these guys in the 4 years I’ve been here. Are they a cyclical species, like some others that only come around every few years or so? Just curious. Thanx for the great pix and description.
Thanks again for your response. I just wanted to add that I thought it was interesting how it dug itself into the mulch after taking this pic. I saw another comment on the Fig Eater of how this is normal behavior for egg laying. Thanks again for what you do!
Gorgeous!
Is it possible to find these beetles in Kentucky? Because I am attending Breyerfest in Lexington and believe I’ve seen some by the pool.
A relative, the Green June Beetle, is native to Kentucky. See BugGuide.
Dear Bug Man folks,
We’ve noticed this beautiful metallic green insect around our garden a few times, so brought in
a belly-up one and found your description, photos etc. Perfect! I got a great specimen of a fig eatin’ Cotinis mutabilis. After I looked it up I was going to do some research on insects, but you had that all down pat too! YOU PEOPLE ARE THE BEST!!! Now I know they like (summer) fruits, and we have around 17 fruit n’ nut trees including figs. Their larvae are apparently laid in compost or rabbit dung etc. Well with 2 more-or-less working compost piles, I guess we’ll always have our share of ’em. Interesting to read all the emails you posted too. Especially the one about how that mommy bug buried deep in someone’s rabbit dung to lay some eggs probably! How on earth do they get themselves to actually look METALLIC?!?
I want to glue the insect’s back to a piece of glass, and frame it over a mirror as it’s posterior / underside is such a pretty color. Framed up in (metallic light green) in a deep enough frame would be kind of neat, with a kelley green mat, huh?
Not bugged by the bug anymore,
Eleanore
I was told it was a Japanese Beetle decades ago. I’m glad to finally see what it REALLY is and what a Japanese Beetle is! Thanks so much!
A few days ago some jerk said it was a Blue Tail Fly. It seems there’s not much info out there on Blue Tail Flies, and most images have photos of blue dragonflies. Wrong! All I could find on Blue Tail Flies was that they are a Horse Fly, but I can’t find any images. Anyone out there have a good photo of a Blue Tail Fly?
We have tons of these here in Kansas. They are feeding on our tomatoes!
They are actually swarming my fig tree. I won’t have any fruit left Glad to know they are harmless as I was afraid due to the number of them
Looks like s Hitchcock movie here in Cottonwood AZ!
I’ve been seeing so many of these here in Southern California but I don’t recall ever seeing them when I lived here before, which was 1967-1994. Are they a recent transplant to the Los Angeles area? Thank you!
Figeaters are not new to Los Angeles. They are active during the heat of summer, especially July and August, and perhaps there are more fruit trees in your new location.
It’s a different climate and a few large hilly separations between West Los Angeles and Pasadena, so I guess that’s the reason.
Thanks for your reply.
I have encountered this before. This is the first time I have ever seen it mentioned by anyone except myself. A figeater beetle a few years back shot hot liquid out his/her sides. Not hot enough to hurt, I just got startled. The beetle was completely fine, in case you wondered.
Thanks for providing a second account of having had this experience.
How do we control the larva or the bugs without dangerous chemicals as they are eating our nectarines! We live in central Nebraska. Thank you.
I hate bugs and these freak me out. They fly right in my face, one rode on my mother on her shirt into a restaurant and she had no idea until someone told her. Do they bite or sting? Thanks.
They do not sting, nor would they be prone to biting.
We have a big problem in our community garden here in Santa Fe Springs CA but I have come up with away to trap them without chemicals you just need a 2 liter bottle and cut the top off around where the paper on the out side ends and put a fruit in it like a peach the more ripe the better drop it in the bottom and flip the top you cut off so the part you poured is now facing down like a funnel and i masking tape the side to hold it in place. The Green Fig Beatles will be attracted to it and fall in and can get out i’v caught and killed over 16,000 in the last 2 years here. I start putting the bottle out at the first sing of them usually in late June early July
Hello… just a word question… I live in California and recently have had several large flying beetles (6) flying around in my house on different days? No open doors or windows for them to come in through just randomly found inside.. don’t know how they are getting in and was wondering if somehow they were laying eggs or hatching somewhere in unaware of?? July August & September? Thought maybe you could give me some insight?
Hi. Are you able to send us a photo or two? We can try. You can do that here.

Thanks for the explanation and photos. I’ve lived in my home in N. Cal for over 30 years and just saw my first one today. It was really pretty and I had to go look it up. My neighbors fig tree is full of fruit so this make perfect sense.
Cheers!
