The brown prionid beetle is a type of long-horned beetle known for its distinctive appearance and wood-boring habits.
While beetles from other families, such as cerambycids, have been known to be troublesome pests inside homes, it’s natural to be curious about whether or not the brown prionid beetle presents any danger to humans.
When it comes to beetles of this nature, a common concern is if their bite is poisonous.
Examining this is important, as many other insects, such as wasps and spiders, can cause significant harm through venomous bites or stings.
It’s essential to understand the potential risks associated with brown prionid beetles and similar species.
Brown Prionid Beetle Overview
Classification and Description
The Brown Prionid (Orthosoma brunneum) is an insect belonging to the family Cerambycidae, also known as longhorn beetles.
This species falls under the genus Orthosoma within the subfamily Prioninae and tribe Prionini. As part of the order Coleoptera, these beetles are classified in the class Insecta, within the phylum Arthropoda and kingdom Animalia.
- Size: Adult Brown Prionids can grow up to 1.5 inches long
- Color: They have a distinct reddish-brown to dark brown coloration
Habitat and Distribution
Brown Prionids are native species commonly found across the United States. They reside in various habitats, such as:
- Forest edges
- Woodlands
- Rotting logs or stumps
Life Cycle and Diet
The life cycle of Brown Prionids includes the following stages:
- Egg
- Larva
- Pupa
- Adult
Larvae of these beetles are cream to brown in color and grow up to 3 inches in length over a three to five-year period.
They primarily feed on decaying wood, while adult beetles consume tree sap and plant nectar.
Brown Prionid Beetle Bite Characteristics
Physical Features
The brown prionid beetle has strong mandibles that can deliver a bite. However, their bite is not poisonous. Key physical features of the bite are:
- A small puncture mark
- Minor bleeding
Pain and Swelling
Bites from brown prionid beetles can cause some pain and swelling. Symptoms may include:
- Mild to moderate pain
- Localized redness
- Swelling around the bite area
Comparison with Other Insect Bites
Comparing brown prionid beetle bites to other insect bites:
Insect | Bite Symptoms | Poisonous? |
---|---|---|
Brown prionid | Pain, redness, swelling | No |
Spider | Variable, may cause severe pain, necrosis | Some species |
Mosquito | Itchiness, redness, swelling | No |
Cockroach | Red, itchiness | No |
The brown prionid beetle bite is generally less severe than some spider bites and involves fewer symptoms than those caused by mosquitoes and cockroaches.
Remember to seek medical advice if symptoms worsen or persist, as individual reactions may vary.
Is the Brown Prionid Beetle Poisonous?
The Brown Prionid Beetle, also known as the California Prionus, is a type of beetle that can cause concern due to its large size and powerful mandibles.
However, it is important to know if a bite from this beetle is poisonous or not.
- Venom: Brown Prionid Beetles do not produce venom. They primarily feed on plant materials and do not have a venomous bite.
A bite from a Brown Prionid Beetle can cause some symptoms, but they are generally mild and not life-threatening.
- Local reaction: A bite may result in a red mark on the skin. This is a typical response to physical trauma from the beetle’s strong mandibles.
- Discomfort: Some discomfort may follow a bite due to the pressure exerted by the beetle’s jaws.
Despite the lack of venom and mild reactions to a bite, it is essential to take some precautions around Brown Prionid Beetles:
- Do not handle them with bare hands; instead, use gloves or tools if necessary.
- Keep a safe distance when observing these beetles in the wild.
In summary, Brown Prionid Beetles are not poisonous, and their bites are not venomous. However, it is crucial to be cautious around them and handle them with care if needed.
First Aid and Prevention
Immediate Treatment
If bitten by a brown prionid beetle, it’s vital to clean the wound with soapy water immediately. This helps reduce the risk of infections.
Possible Infections and Complications
Although brown prionid beetle bites aren’t poisonous, there can be risks of infections or complications.
Some people might experience an allergic reaction to the bite. Also, an unclean bite can lead to infections, which may cause diseases.
Protective Measures
To prevent brown prionid beetle bites, follow these measures:
- Wear long pants and long-sleeved shirts, which can reduce direct contact with beetles.
- Avoid handling or disturbing the beetles.
Brown Prionid Beetle Infestation
Signs of Infestation
Brown Prionid Beetles can cause damage to various plants and trees, with a particular preference for decaying wood. Some signs that these beetles have infested an area include:
- Presence of adults: Adult beetles are relatively large, with a length ranging from 1-1.5 inches. They have a cylindrical body and can be easily identified by their dark chestnut-brown color.
- Larvae in moist decaying wood: Brown prionid larvae favor moist decaying wood as their primary habitat. If you come across larvae in such areas, it is a sign of infestation.
- Exiting holes on wood: When the larvae finish their development, they will create exit holes in the wood.
Potential Damage
Brown Prionid Beetles are known as root borers, and their larval stage can cause significant damage to the roots of various plants and trees including oak and firs.
The primary damages caused by these beetles are:
- Weakening of structural integrity: The infestation can weaken the overall structural integrity of the affected trees, eventually leading to their collapse.
- Death of plants and trees: Prolonged infestations can ultimately lead to the death of plants and trees as their roots are damaged over time.
Control Measures
Effective control measures to manage a Brown Prionid Beetle infestation are:
- Removal of decaying wood: As the larvae prefer moist decaying wood, removing these materials from your property can significantly reduce the chances of an infestation.
- Trimming of shrubs: Maintaining proper landscaping by pruning shrubs and eliminating excess vegetation impedes the beetle’s access to potential host plants.
- Chemical treatments: In cases of severe infestation, applying appropriate insecticides targeting both adult beetles and larvae may be necessary.
It is essential to monitor and identify potential infestations early to prevent significant damage to plants and trees.
Additionally, as the Brown Prionid Beetle is primarily an outdoor pest, infestations rarely occur inside structures such as basements or attics.
However, these beetles are not poisonous to humans or pets, so the primary concern should be focused on the potential damage they can cause to plants and trees.
Bug Control Recommendation Tool
Conclusion
The Brown Prionid Beetle, with its distinctive appearance and wood-boring habits, often piques human curiosity.
While their size and strong mandibles might seem intimidating, it’s reassuring to know that these beetles are not poisonous and their bites, though potentially painful, are not venomous.
Their primary diet consists of decaying wood and plant nectar, and they play a significant role in the ecosystem by aiding in the decomposition process.
However, like many insects, they can become problematic in large numbers, especially when their feeding habits lead to damage to plants and trees.
It’s essential to recognize their presence, understand their behavior, and take appropriate measures if needed, always keeping in mind the balance of nature.

Thank you so much for providing the identification information on this six year old posting. We will also tag the posting with all three families represented in the collection.
Possibly Enoplocerus armillatus.
Thanks Mardikavana.
Can you eat them?
Those grubs are edible and tasty. Only a few times i have helped processs some trees from Cedar Mountain, southern Utah. We would find these and also “flathead” grubs(buprestid?).
I could never eat them raw because of the goo factor. But they are delicious after you toast them for a minute or two. They taste like pine nuts. I would like to eat them again.

I found the same type grub in the stump of a tree that I was removing from my parents lawn. I believe it was an oak tree of some type – as I only had the stump of that particular tree and the other trees to go by…
That grub was about 3 inches in length and is what my nightmares are made of.
Give me wild carnivores or poisonous snakes over those creepy looking things any day
