The Lifecycle of a Click Beetle
Reproduction Process
Click beetles mate to reproduce, and the females lay their eggs in a suitable environment for the larvae to thrive. Typically, this includes soil or rotting logs1. The eggs hatch into worm-like larvae called wireworms2.
Growth from Larvae to Adult
The life cycle of click beetles consists of four stages: egg, larva, pupa, and adult3. The larvae, known as wireworms, are usually hard-bodied, brownish, and cylindrical4. They live, feed, and grow for 1 to 4 years in their natural environment5, developing through several molting stages before pupating and transforming into their adult form6.
Adult click beetles are elongated, range in length from 6.4 to 19.1 mm, and most are uniformly brown to black in color7. They have a unique pair of spurs and sometimes display colorful markings on their thorax8. Interestingly, they can bend their bodies and suddenly straighten out to propel themselves into the air. This motion produces a distinctive “click” sound9.
In a nutshell, the lifecycle of a click beetle involves its transformation from an egg to a wireworm larva, followed by the pupation stage, and ultimately reaching its adult form. During their life, click beetles consume various forms of plant material, contributing to the ecosystem as decomposers and nutrient recyclers10.
Click Beetles and Humans
Pest Control
Click beetles, belonging to the family Elateridae, can become a nuisance to humans when they infest yards, gardens, and even homes. As pests, their larvae (called wireworms) are particularly harmful to various crops like wheat, corn, cotton, and grains1. If you suspect a click beetle infestation, consult an entomologist or a pest control professional for proper identification and management options.
One common method for controlling click beetle populations is the use of pesticides2. However, you must be cautious when using such products, as they can also impact beneficial insects. Always follow the label instructions and consult with a professional if needed.
Example: A pesticide containing the active ingredient carbaryl can be useful in controlling click beetle populations3.
Comparison Table:
Pesticide | Active Ingredient | Target Pests | Advantages | Disadvantages |
---|---|---|---|---|
Example | Carbaryl | Click beetles | Effective | Non-selective |
Prevention and Management
Preventing a click beetle infestation begins with good yard and garden maintenance. Keep your gardens free from debris and weeds, as this can help reduce their potential hiding spots4. In your crops, consider employing crop rotation and the addition of beneficial insects like ladybugs to keep click beetles in check5. Pheromone traps can also be used to monitor and reduce their population6.
If click beetles enter your home, try to seal any potential entry points like cracks and gaps. Ensure proper ventilation, reduce humidity, and promptly replace damaged wood, as these measures can help create an unfavorable environment for these insects7.
To recap, here are some prevention and management tips:
- Maintain clean yards and gardens.
- Use crop rotation and beneficial insects in gardens and crops.
- Install pheromone traps to monitor and reduce click beetle populations.
- Seal entry points, ensure proper ventilation, and reduce humidity in homes.
Click Beetles and the Ecosystem
Prey and Predators
Click beetles are a part of the ecosystem, playing a vital role in the food chain. They are known to feed on various organisms like aphids and other insects. They also consume flowers, aiding in the pollination process. On the other hand, they serve as a food source for predators like birds and small mammals. For example, eastern eyed click beetles have large spots on their thorax that resemble eyes, helping to deter potential predators.
Impact on Soil and Agriculture
The larvae of click beetles, known as wireworms, have a significant impact on both soil and agriculture. Wireworms can be beneficial in that they help break down organic matter, thus improving soil texture. However, they can also pose a threat to plants, as they feed on roots, seeds, and stem bases, causing damage to crops.
Types of wireworms:
- Predatory
- Herbivorous
Predatory Wireworms | Herbivorous Wireworms |
---|---|
Feed on other insects | Feed on plant roots |
Beneficial to soil life | Damaging to crops |
Less harmful to plants | Higher risk to agriculture |
In small numbers, wireworms may not be too concerning, but when their populations increase, they can cause substantial damage to crops. To manage and control their numbers in agriculture, various approaches are utilized, including monitoring, prevention, and targeted treatments against them.
In conclusion, click beetles play a crucial role in ecosystems as both prey and predators. Additionally, their larvae, the wireworms, interact with soil and agriculture, contributing to the ecological balance. But they can also harm crops, and on the agricultural side, these pests require careful monitoring and management for the success of farming systems.
The Click Beetle Family
Elateridae and Eucnemidae
Click beetles belong to the Elateridae family, which is part of the larger Coleoptera order. They are closely related to the Eucnemidae family. Both families share similarities in their body structure and behavior. Here are a few key features of click beetles:
- Cylindrical or elongated body shape
- Hardened protective wings
- Ability to “click” and launch themselves into the air
- Nocturnal behavior
Famous Species
Alaus oculatus: The Eyed Click Beetle
One famous and easily recognizable species is the Eastern eyed click beetle (Alaus oculatus). This unique beetle is found throughout South Carolina and notable for its striking appearance. You’ll easily identify it by its:
- Large size, sometimes up to 1.5 inches in length
- Black body color with white spots
- Large, distinctive eye spots on its back
But don’t worry, these large eye spots are not real eyes – they serve as a defense mechanism to confuse predators. Also, you can be confident that Alaus oculatus and other click beetles pose no harm to humans or pets.
Deilater: Another fascinating genus within the Elateridae family is Deilater. These beetles display similar characteristics to other click beetles but are often found in tropical regions.
So, as you explore the world of click beetles, you’ll notice that both the Elateridae and Eucnemidae families showcase a diverse range of fascinating species. Their unique clicking abilities and captivating appearance make them a truly intriguing part of the insect world.
Unique Characteristics
Clicking Mechanism
Click beetles, also known as snapping beetles, spring beetles, or skipjacks, have a fascinating clicking mechanism. This enables them to make a clicking sound and perform swift movements. You may have come across these beetles flipping into the air with a sudden snap.
How does this work? The click is generated when the beetle arches its body and uses a spine on its prosternum to engage a notch on the mesosternum. When the tension is released, energy is set free, propelling the beetle into the air. This mechanism is perfect for escaping predators or getting back on its feet when it’s turned over.
Bioluminescence
Some click beetle species exhibit bioluminescence, which is the ability to produce light in the dark. Bioluminescent click beetles can emit a green or yellow glow from their bodies. You may have noticed these beautiful displays at night in wooded areas, lawns, or crossing paths on warm evenings.
Certain bioluminescent click beetle species can be found in the Southern United States, Central, and South America. These fascinating creatures produce their ‘glow’ through a process called chemiluminescence, where the light is generated through a chemical reaction between an enzyme called luciferase and a substrate called luciferin.
In closing, click beetles have their unique features like the clicking mechanism and bioluminescence, which make them captivating to observe in their natural habitats. Remember to appreciate their intriguing characteristics if you happen to encounter one on your outdoor adventures.

Another significant avenue of research is their role in the ecosystem. Click beetles are known to feed on a variety of insects and invertebrates, such as caterpillars, becoming natural predators in certain environments. Future studies could explore how click beetles contribute to controlling pest populations.
Additionally, understanding their lifecycles, including their mating habits and reproductive success, can provide valuable insight into their population dynamics. Comparing these factors between different species of click beetles may reveal essential differences and similarities.
Here are some features of click beetles worth investigating in future research:
- Habitat preferences
- Role in the ecosystem
- Lifecycle and reproduction
- Variations between species
In conclusion, there is still much to discover about click beetles, from understanding their habitat preferences to uncovering their role in ecosystems. By conducting further studies, we can improve our knowledge of these fascinating insects and better protect their populations for the future.

i <3 click beetles!
Found this same Click Beetle at our house in Tagaytay City, Luzon, Philippines several weekends ago. First time to see a click beetle this big. Around 2.75″ long (antennae not included) and clicking like crazy when I held it and when I turned it over.
Attached is a pic of it in my Facebook account.

I found 1 similar to that Click Beetle and I’m in Ho Chi Minh City, Vietnam. I took pictures of it and released it.
I think this is likely a click beetle, my first impression from the shape. Perhaps Danosoma obtectum. http://bugguide.net/node/view/86398
That does look like a good match. Thanks for the assistance.
Hi Kay,
I studied phylogeny of click beetle in Taiwan.
The photo you took looks like species belong to genus Oxynopterus in subfamily Oxynopterinae.
Most of Oxynopterus distributed in SE Asia. Megalorhipis is the only subgenus which distributed in Africa.
Can you help me to collect some (1-2 individual) for detail research?
Best wishes,
JF

I found one exactly like this recently near JPL in Altadena, and for the life of me, I cannot get any solid ID on the thing!
Altadena is not too far from our own Mount Washington sightings. Perhaps we will try to contact Doug Yanega at UC Riverside to see if he can provide any information.
