Earwigs are fascinating insects that have intrigued humans for centuries. At OCG Pest Control, we believe in understanding pests to manage them effectively. This comprehensive guide delves deep into the world of earwigs, shedding light on their behaviour, ecology, and relationship with humans.
Earwigs are small, elongated insects known for their distinctive pincers. While often misunderstood, these creatures play a vital role in our ecosystem, contributing to the balance of nature.
The name "earwig" is derived from the Old English word "ēare," which means "ear," and "wicga," meaning "insect." This peculiar name stems from age-old myths suggesting these insects crawl into human ears. But rest assured, this is more fiction than fact!
Earwigs are easily identifiable by their forceps-like pincers, which they use for defence and capturing prey. They have a slender body, two pairs of wings, and are usually brownish.
The European earwig is one of the most common species encountered by humans. Originating from Europe, it has now spread to various parts of the world, adapting to diverse environments.

Externally, earwigs have a segmented body with a tough exoskeleton. Internally, they possess a simple circulatory and well-developed nervous system, making them quite agile.
Earwigs are versatile and can be found in various habitats, from gardens to homes. They prefer dark, damp environments, often hiding under rocks, logs, or crevices.
Female earwigs deposit a clutch of twenty to forty eggs in wood cavities, behind leaves, or in the uppermost layer of soil. After around seven days, the eggs hatch. Although they are lighter in colour, nymphs, or baby earwigs, have the same overall morphology as adults when they are born.
Before being regarded as an adult, they would moult four or five times. Check out the illustration in the article for a visual representation of the earwig's life cycle. Here's the link to the article for more detailed information and the illustration.
There are over 2,000 species of earwigs globally, each with unique characteristics and habitat preferences. In Australia, there are approximately 60 species of earwigs. This is based on a paper titled "The Dermaptera (earwigs) of Australia: a taxonomic treatment of all named species, with an annotated checklist" by David Rentz, published in 2019. This paper provides a comprehensive taxonomic treatment of all named earwig species in Australia.
While both male and female earwigs have pincers, males typically have more curved pincers, whereas females have straighter ones.
Earwigs are nocturnal creatures, coming out at night to feed and returning to their hiding spots during the day. They play a crucial role in the ecosystem, aiding in decomposition and serving as food for various predators.
Earwigs are solitary insects but can be found in groups, especially in favourable conditions. They're known to be scavengers, feeding on decaying organic matter and occasionally preying on smaller insects.
Earwigs contribute to the environment by breaking down organic matter and enriching the soil. They also serve as a food source for many predators, maintaining ecological balance.
Primarily omnivorous, earwigs feed on a mix of plant material, decaying organic matter, and other insects. Their diet varies based on availability and species.
Earwigs have several natural enemies, including birds, amphibians, and larger insects. Some parasitic species also target earwigs, laying their eggs inside them.
Earwigs have evolved to thrive in various environments. Their nocturnal nature, ability to hide in crevices, and varied diet make them resilient creatures.
The relationship between earwigs and humans is complex. While they are beneficial to the environment, their presence in homes can be unsettling for many.
While earwigs can benefit gardens, their presence indoors is often seen as a nuisance. However, they're not inherently harmful to humans.
Contrary to popular belief, earwigs are not venomous and pose no direct threat to humans. Their pincers can give a slight pinch but are generally harmless.
One of the most enduring myths about earwigs is that they crawl into human ears. This is a misconception; earwigs are no more likely to enter our ears than any other tiny insect.
Throughout history, earwigs have found their way into various cultural tales and folklore, often portrayed as mysterious or ominous creatures.
Earwigs can be both beneficial and problematic in gardens. Understanding their role can help gardeners make informed decisions.
Earwigs aid in breaking down organic matter, helping enrich the soil. They also feed on specific pests, providing natural pest control.
While earwigs are beneficial, they can sometimes feed on plants, especially seedlings, flowers, and soft fruits.
Earwigs primarily target the softer parts of plants, such as leaves, petals, and fruits. They can leave behind jagged edges or small holes.
The answer is nuanced. While earwigs can be beneficial, an overpopulation can lead to damage. It's essential to maintain a balance.
With their unmistakable pincers and nocturnal habits, earwigs can cause concern when they appear in large numbers in our homes and gardens. While they play a role in the ecosystem, an unchecked population can lead to unwanted damage, especially to young plants and seedlings.

Earwigs are more than just garden pests. They're fascinating creatures with unique behaviours and adaptations.
Takeaways:
Whether you find them intriguing or a bit creepy, there's no denying that earwigs are remarkable creatures with much to offer regarding understanding insect behaviour and ecology.
Female earwigs are known to guard their eggs, showcasing a rare maternal instinct in the insect world.
While not known for flying, earwigs have intricately folded wings, showcasing nature's engineering marvel. Many species of earwigs have wings and are capable of flying, but they rarely do so. Earwigs have two pairs of wings. The front wings, known as tegmina, are short and leathery and serve as protective covers for the hind wings. The hind wings are membranous, much larger, and folded beneath the tegmina when not used.
While earwigs have the physical capability to fly, they often prefer to remain on the ground and are more commonly seen crawling rather than flying. The reasons for their infrequent flying can vary, but it's believed that their ground-based lifestyle and habitats don't often necessitate flight.
The name "earwig" has led to many misconceptions, but these insects are far more intriguing than the myths suggest. Their unique behaviours, adaptations, and roles in the ecosystem make them a captivating subject of study.
While earwigs can be beneficial, managing their populations is essential to prevent potential damage. Regular inspections, preventive measures, and timely interventions can ensure a harmonious coexistence with these intriguing insects.
A list of scholarly articles, research papers, and books is available for those keen on understanding earwigs in-depth. These resources provide comprehensive insights into earwig behaviour, ecology, and management:

Forceps
Earwigs are odd looking insects which have pincers or forceps protruding from the abdomen. These are somewhat intimidating looking but they are not poisonous, and they do not spread disease.
Size
Depending on the species, adults range in size from 5-25 mm.
Wings
They are slender insects with two pair of wings. Dermaptera means “skin wing” due to the leathery appearance of the wings. The hind wings typically fold under the front wings. Do earwigs fly?
