June beetles, also known as May beetles, are a type of scarab beetle that is commonly found in various regions across the United States. These beetles, which can grow up to 5/8 inches long and appear reddish-brown, are known for their nocturnal activities and attraction to artificial lights during the warmer months of the year Texas A&M University. While they are not considered aggressive insects, it is essential to understand if they pose any risk of biting humans or pets.
In general, June beetles are not known for biting or causing harm to humans, as their primary food source consists of plants and decaying organic matter. However, it is important to note that their larvae, known as white grubs, can cause damage to lawns and gardens by feeding on the roots of plants Integrated Pest Management. Additionally, some beetle species may show a tendency to bite or nibble if they feel threatened or unintentionally come in contact with human skin.
Identifying June Beetles
June beetles, also known as June bugs, are members of the Scarabaeidae family. Among the species in this family, two common types are the Ten-lined June beetle and the Green June beetle (Cotinis nitida). These beetles are generally robust in shape and have a range of colors including metallic green and dark brown. Their elytra, or wing covers, may have reddish-brown or bronze-colored margins.
- Ten-lined June beetle: dark brown to black color, around 1 inch long
- Green June beetle: metallic green color, nearly 1 inch long, bronze-yellow body margins
June beetles are typically nocturnal and are attracted to lights at night. They are known for their characteristic buzzing, which resembles the sound of a toy helicopter. They tend to fly near the ground and may occasionally land on people, which can be mistaken for a bite. Despite some misconceptions, June beetles are not aggressive and do not bite humans.
These scarab beetles are commonly found throughout North and South America. They inhabit a variety of environments including forests, gardens, and grasslands. Their larvae, known as grubs, are found in soil and feed on plant roots, while adult beetles feed on leaves and fruits of various plants.
- Soil: grubs are often found in turfgrass
Do June Beetles Bite?
Interaction with Humans
June beetles are not known to bite humans. They are typically more of a nuisance due to their attraction to outdoor lights during the night. However, they may move in a clumsy manner when walking or flying, coming into contact with humans occasionally. While June beetles pose no direct threat, they may startle adults, children, and pets when they are touched, and they may emit a hissing noise when disturbed.
June beetles have some basic defense mechanisms, including:
- Hissing noise: When threatened or molested, they can produce a hissing noise by rubbing their wings against their thorax. This sound might scare off potential predators, like birds and small mammals.
- Appearance: Their large size and robust appearance may deter some predators from attacking.
|Interaction with humans||Not known to bite; may startle when touched|
|Interaction with pets||No threat|
|Interaction with birds||Deterred by hissing noise|
|Interaction with children||No threat; may startle|
In summary, June beetles are not known to bite humans or pets and primarily serve as a nuisance due to their attraction to lights. Their defense mechanisms involve a hissing noise and their appearance, which can deter predators like birds but are not harmful to humans or pets.
June Beetle Life Cycle and Diet
Eggs and Larvae
June beetle eggs are laid in the soil, where they hatch into larvae commonly known as white grubs. The following are some characteristics of their eggs and larvae:
- Eggs: Laid in June to early July
- Larvae (white grubs): Cream-colored with three pairs of legs, up to 1¼ inches long
The larvae feed on:
- Plant roots
- Broadleaf weed
- Tree and shrub roots
Example of damage caused by larvae:
- Chewing turfgrass roots, leading to reduced growth or wilted appearance
Pupa to Adult June Bug
June beetles undergo metamorphosis and transform into a pupa, then into an adult june bug. Here are some characteristics of the pupa and adult stages:
- Pupa: Brown, ½ inch long
- Adult June Bug: Almost 1-inch long, metallic green with bronze to yellow body margins, sometimes reddish-brown wing covers
Adult June beetle diet:
Pros and Cons of June Beetles’ Presence:
- Destroy plants and turfgrass
- Damage rose gardens
Comparison Table: Life Cycle Stages
|Larvae (Grub)||Up to 1¼ inches long||Cream-colored||Plant roots, grass, shrubs|
|Pupa||½ inch long||Brown||None|
|Adult June Bug||Almost 1-inch long||Metallic green, yellowish margins, sometimes reddish-brown wing covers||Foliage, flowers, roses, corn|
June Beetle Pests and Damage
Impact on Plants and Trees
June beetles, specifically the Green June Beetle and the May/June Beetle, are known for causing damage to plants and trees. Their larvae, known as grubs, feed on the roots of various plants, leading to wilting and sometimes death.
- Green June Beetle larvae damage roots of grass, trees, and ornamental plants
- May/June Beetle grubs consume roots of grasses, broadleaf weeds, and shrubs
As adults, beetles from the Phyllophaga genus may also feed on tree leaves, creating ragged holes. They are nocturnal and often attracted to doors and windows where light is present.
In addition to causing harm to plants, June Beetles can cause property damage. Infestations of their larvae may result in unsightly brown patches on lawns. Moreover, Japanese Beetles, a relative of the June Beetle, are known for causing extensive damage to foliage and flowers.
|Beetle Type||Damage to Plants||Damage to Property|
|Green June Beetle||Roots, leaves||Brown patches on lawns|
|May/June Beetle||Roots, leaves||–|
|Japanese Beetle||Foliage, flowers||–|
Sometimes, June Beetles may be confused with Chafer Beetles, another type of beetle that causes similar damage to lawns and plants.
Pros and cons of controlling June Beetles:
- Protects plants from damage
- Preserves the appearance of lawns and gardens
- Reduces the chances of further infestations
- Use of chemical pesticides may be harmful to the environment
- Invasive methods may disrupt the ecosystem
It is important to take appropriate measures to control June Beetle infestations and prevent any further damage to plants and property. Regular monitoring and use of eco-friendly treatment options can help minimize their impact.
Natural Predators and Pest Control
Animals that Prey on June Beetles
June beetles have several natural predators that help control their population:
- Moles: These animals feed on the larval stage of June beetles, known as white grubs.
- Skunks and Raccoons: They dig up turf to eat the larvae, which can cause damage to lawns but help reduce beetle populations.
- Birds: Various bird species will eat adult June beetles as well as their larvae.
- Bats: These nocturnal creatures feed on adult beetles during their active flight periods.
Biological Control Methods
There are also some biological control methods that can help manage June beetle populations:
- Beneficial Nematodes: Applying beneficial nematodes to the soil can target the larval stage and provide effective pest management.
|Moles||Effective on larvae||May damage lawns|
|Skunks & Raccoons||Eat larvae||Can cause lawn damage|
|Birds||Eat larvae and adult beetles|
|Bats||Feed on adult beetles during flight|
By using these natural predators and biological control methods, it is possible to control June beetle populations and minimize the damage they can cause to your garden and landscape.
June Beetle Prevention and Management
Insecticides and Pesticides
In controlling June beetles, a variety of insecticides and pesticides are available. Some common insecticides include imidacloprid, which is effective against both adult beetles and their grubs.
- Effective in controlling June beetles
- Targets both adults and grubs
- May harm beneficial insects
- Potential chemical exposure risks
DIY Pest Control Measures
For homeowners who prefer a more natural approach, several DIY pest control methods can be employed. For example:
- Using molasses traps, which lure June beetles with their scent and then trap them in a sticky solution
- Placing commercial beetle traps around the yard, which also attract and capture beetles with their specific pheromones
Maintaining a Healthy Lawn
A healthy lawn is the foundation for successful June beetle prevention. Here are some key steps to achieve it:
- Regularly mow and water the grass
- Limiting thatch build-up, as it can serve as a food source for larvae
- Keep trees and shrubs well-pruned
Comparison of Pest Control Methods:
|DIY Pest Control||Moderate||Low||Low|
By applying research-based measures like insecticides, DIY pest control, and lawn care, homeowners can prevent June beetle infestations and maintain a healthy living space.

Letter 1 – Swarming Behavior in the Green June Beetle
June bug in July?
We just moved into our new house located in the middle of Maryland, just west of Baltimore, in late May. In mid to late June I saw some patches (5 to 10 bugs) of fairly large bugs flying around in a section of the yard. As of yesterday, that number has increased exponentially. There were easily several hundred, if not a thousand or more of them flying around. They don’t seem to be eating anything and as the day wore on and got hotter, they seemed to disappear, I assuming in the grass. Looking through your beetle list, they come close to the June Bug. Will they do any damage to my lawn and how can I get rid of them? Any help? Thanks,
You have Green June Beetles, sometimes called Figeaters, Cotinis (occasionally Cotinus) nitida. While researching this swarming behavior, of which we have received other reports in the past, we found that occasionally large numbers will swarm over grassy areas on warm sunny days. The National Parks Services Integrated Pest Management page has much information on the Green Fruit Beetle including: ” The green June beetle ( Cotinus nitida ) adult is usually 3/4″-1″ long, and 1/2″ wide. The top side is forest green, with or without lengthwise tan stripes on the wings. The underside is a metallic bright green or gold, bearing legs with stout spines to aid in digging. In the mid-Atlantic region the names ‘June bug’ and ‘June beetle’ are commonly used for this insect, while they are called “fig eater” in the southern part of their range. They should not be confused the familiar brown May or June beetles that are seen flying to lights on summer nights. The green June beetle adult flies only during the day. The larvae are white grubs often called ‘richworms’ because they prefer high levels of organic matter for food. With three growth stages, the beetles develop similarly to the other annual scarab species. Their body lengths reach 1/4″, 3/4″, and 2″ respectively. The larvae have stiff abdominal bristles, short stubby legs, and wide bodies. One unique characteristic of this grub is that it crawls on its back by undulating and utilizing its dorsal bristles to gain traction. Other typical white grubs, like the Japanese beetle grub, are narrower, have longer legs, crawl right side up, and when at rest assume a c-shaped posture. This species is native to the eastern half of the United States and overlaps with Cotinis texana Casey in Texas and the southwestern United States. The adults generally do not feed but occasionally become pests of fruit. Any thin- skinned fruit such as fig, peach, plum, blackberry, grape, and apricot can be eaten. The principal attraction is probably the moisture and the fermenting sugars of ripening fruit. They occasionally feed on plant sap. In turf situations egg-laying females are attracted to moist sandy soils with high levels of organic matter. Turf areas treated repeatedly with organic fertilizers, composts, or composted sewage sludge become more attractive to the female. The grub feeds on dead, decaying organic matter as well as plant roots. This species is commonly associated with both agricultural crop and livestock production areas as well as urban landscapes. Field-stored hay bales, manure piles, grass clipping piles, bark mulches, and other sources of plant material that come in contact with moist soil provide prime microhabitats preferred by both the female for egg-laying and the migrating third instar grubs. The green June beetle completes one generation each year. Adults begin flying in June and may continue sporadically into September. On warm sunny days, adults may swarm over open grassy areas. Their flight behavior and sounds reassembles that of a bumble bee. At night they rest in trees or beneath the thatch. After emerging, the adult females fly to the lower limbs of trees and shrubs and release a pheromone that attracts large numbers of males. Frequently, males repeatedly fly low and erratically over the turf trying to locate emerging females. After mating, females burrow 2″-8″ into the soil to lay about 20 eggs at a time. The spherical eggs are white and almost 1/16″ in diameter. Most eggs hatch in late July and August. The first two grub stages feed at the soil thatch interface. By the end of September, most are third instar larvae and these large grubs tunnel into the thatch layer and construct a deep vertical burrow. The grubs may remain active into November in the mid-Atlantic region. In the more southern states grubs may become active on warm nights throughout the winter. In colder areas they overwinter in burrows 8″-30″ deep. The grubs resume feeding once the ground warms in the spring and then pupate in late May or early June. The adults begin emerging about three weeks later. “

What is this??
Tue, May 26, 2009 at 6:55 PM
This is a picture of a bug I saw on my garbage can in southern California. I have never seen this kind of bug before. In person the orange on the bug is a lot more orange than it shows in the picture. It was at least an inch long and 1/2 inch wide, possibly bigger. It is orange, white and blackish. The white and black are verticle stripes and the orange is on its legs and face.
Is it a bity bug? Is it a poisonus bug? Is this the sort of bug that might move into our house and have lots of little funny looking bugs? How do I get rid of this sort of bug?
Other than munching on some pine tree needles, the Ten Lined June Beetle will not do you nor your home any harm. It will not bite. It is not poisonous, and it will not move into your home to procreate. The grubs live underground and feed on the roots of a variety of plants, but they are never numerous enough to cause damage. Turn off the porch light at night and you will need not fear attracting Ten Lined June Beetles to your house.
Letter 4 – Scarab Grubs: June Beetles or Rhinoceros Beetles?????
November 19, 2010
Found these in our compost heap (and no you are right – I do not turn it over nearly often enough…). I’ve never seen or heard about giant grubs like these – they are placed on a standard sized garden trowel to give you a sense of the scale. I was honestly a little too grossed out to try to straighten one out to measure it though I know right where to find more if you need me to.
I didn’t destroy them all outright (my 1st impulse) just in case they are beneficial or morph into something gorgeous. Can you identify them for me? Location: Rollingwood, Texas 11/19/10…Thanks as always! Deb Wilson
We love your photo. You have a good cellular camera. We increased the resolution to make your tiny file larger, and it held up nicely. We hope that by making a reference to a recipe, we could get David Gracer to salivate and entice him into sending in an edibility comment. Though we are certain they are Scarab Beetles, we are unsure if they are June Beetles or Rhinoceros Beetles.
Thank you! I do have fun with my camera out in the garden.
I am fairly certain (due to the size) these are rhinoceros or ox beetle grubs. I’m basing that (though I admit I am lousy at bug ID) on the fact that I unearth June Bug/Beetle grubs out in the soil consistently in these parts. They are much smaller – about the circumference of a pencil and rarely more than 1/2 inch though in their curled in the ground state, length is a guess.
These grubs were in our compost heap, and were up to 3 1/2 inches long, with a diameter ranging from 3/4 to a full inch or more on the larger tail end side. Since I was thinking they were ox beetles (and therefore not out there garnering strength and numbers to launch a beetle apocalypse on my garden beds) I simply put them back into the compost heap after I took the photos.
If these grubs are edible (and I say that knowing how a person defines “edible” varies), then a few of them could make a fairly decent meal, depending of course on if you have to remove any parts, if they shrink during preparation, etc. And now I have to go look at photos of puppies and rainbows because I just totally grossed myself out.
Have a great weekend! /Deb Wilson

Just bought a house in Bermuda Dunes, in the hot desert of Coachella Valley, California. This past three weeks our yard has been inundated with these beetles (please see picture). We’ve tried to identify it by searching the web for a similar picture, but can’t find one. Can you possibly tell us what kind of beetle this is?
Thanks in advance.

This is a Lined June Beetle in the genus Polyphylla, but we are not certain of the species. Based on the species posted to BugGuide, one possible species identification might be Polyphylla cavifrons which is pictured on BugGuide and looks very similar, though BugGuide does note “Species identification often difficult.” We tried searching for the genus in Coachella Valley and discovered an article on Digital Commons that mentions a new species, Polyphylla aeolus, from your area. The images on BugGuide do look similar but they appear to have more markings on the elytra than your individual.

While we understand that a common name for this Scarab Beetle is a June Bug, and like the Lady Bug, this is actually incorrect as both are beetles. May Beetle or June Beetle is a more correct common name. Thanks so much for submitting your Bug Love photos. We are not the best at deciphering the difference between the species of June Beetles but we believe these may be members of the genus Cyclocephala which are classified as Rhinoceros Beetles in the subfamily Dynastinae based on photos on BugGuide where they are referred to as Masked Chafers. For the record, Charles Hogue acknowledges that they are in the subfamily Dynastinae, but still includes them with the June Beetles in his book Insects of the Los Angeles Basin. We have been noticing a very small species of June Beetle, about 1/8 inch long, at our own porch light this summer in the Los Angeles neighborhood of Mt Washington.

Found in my garage, July 3, west of Tulsa Oklahoma. Have seen only this one, have never seen one like it before. I released it into the woods hoping it would find a mate and make more. Will I regret that?
This is a Lined June Beetle in the genus Polyphylla, but it is not the most common species we are asked to identify, the Ten Lined June Beetle. See BugGuide for images and reported sightings of many of the members of this genus. The well-developed antennae indicates that this is a male. We believe releasing your individual was a fine decision.
Thank you very much, Daniel! From your website photos I had begun to believe it was the Lined JB but your confirmation is good to have. I hope he is out there with a mate!
Thanks for all your work in identifying “bugs” and your website is informative & beautiful.

Dear Curious Friend,
This is a Lined June Beetle in the genus Polyphylla, and according to BugGuide: “Large June beetles, most with obvious white scales on elytra often forming stripes. Species identification often difficult.” It might be a Ten Lined June Beetle, Polyphylla decemlineata, which does range as far east as Colorado. What you have called “lashes” are actually the flabellate or fan shaped antennae that characterize the male June Beetles in this genus.

What Is Going On Here?
Location: San Antonio, TX
April 23, 2012 12:36 pm
Hey Bugman! I live in San Antonio, TX and over the last few weeks we have had TONS of butterflies flying around our yard. The other day I noticed a bunch of them hanging out on a certain tree. Today (4/22/12) I went outside and took a picture of them gathered around the same spot. Once I loaded the pictures to my computer I was surprised to see the beetles that I didn’t even realize were there when I took the picture. Why are they all hanging out together. I attached two pictures. One where you can see the butterflies pattern and the other is of 5 butterflies and 4 beetles.
This is such a marvelous documentation. The tree is oozing sap and the butterflies and beetles are feeding on the sap. Many butterflies take sustenance from places other than blossoms, and sap is a common food for many species of butterflies including these Red Admirals. The beetles appear to be Green June Beetles or Figeaters, or a closely related species. We wish your photos had a higher resolution, but they are still quite wonderful. Here is a similar documentation from our archives, though the butterfly is a Mourning Cloak.

This gorgeous spider has been living in the same spot amongst my thornless blackberry vines all summer. She looks like a crab spider to me, but I’ve never seen one like this before. She lives in my backyard in Birmingham, Alabama.
We hate to be the bearer of bad news, but this is not a spider. We believe it is the head and thorax of a Green June Beetle, Cotinis nitida. Compare your image to this photo on BugGuide. We suspect a bird or other predator feasted on the fat abdomen and left these remains behind. Have you ever seen it move during the time you observed it?
I gave my “spider” a poke after receiving your email, and you are right… I have been admiring a carcass for the past few weeks! Hee hee!

Speaking of flying objects… This fellow thought my eyeglass frame was a perfect landing site while we sat outside eating on the patio on a hot summer night. He was clearly attracted to the lights. I think it’s a 10-line June Beetle (Polyphylla decemlineata)? When I first picked him up (a “him” because of his fan-like antennae for sensing female pheromones), he let out a breathy, indignant squeak! I took him out to the pine duff where he might enjoy a healthy beetle supper of pine needles. He’ll also avoid further collision with me or a lit window out there. Thought you’d enjoy the images.
