Fact Check: Are centipedes insects?

Are Centipedes Insects?

The claim in question is whether centipedes are classified as insects. This inquiry touches on the broader classification of arthropods, a diverse group of invertebrates that includes insects, arachnids, and myriapods (which encompass centipedes and millipedes).

What We Know

Taxonomic Classification: Centipedes belong to the class Chilopoda within the phylum Arthropoda, which also includes insects (class Insecta), arachnids (class Arachnida), and myriapods (class Myriapoda) 1 9. While all these groups share certain characteristics, they are distinct classifications within the arthropod phylum.
Differences from Insects: Centipedes are not classified as insects due to several anatomical and biological differences. For example, centipedes have a segmented body with one pair of legs per body segment, while insects typically have three main body segments (head, thorax, abdomen) and three pairs of legs 10. Furthermore, centipedes possess a pair of venomous claws (forficules) used for hunting, which is not a feature of insects 3 9.
Lifespan and Reproduction: Centipedes generally have longer lifespans than many insects, with some species living for several years 1. This longevity, along with their reproductive strategies, further distinguishes them from insects, which often have shorter life cycles and different reproductive behaviors 1.
Ecological Role: Centipedes are predatory arthropods that feed on insects and other small invertebrates, contributing to the ecological balance 3 9. This role is similar to some insects, but their classification remains separate.

Analysis

The sources consulted provide a range of insights into the classification of centipedes.

Wikipedia 1 is a widely used resource, but it is important to note that while it can be a good starting point, it may not always be the most reliable due to its open-edit nature. However, the information regarding centipedes' classification aligns with established biological taxonomy.
The National Park Service articles 2 4 offer credible information as they are produced by government entities focused on education and conservation. They clearly state that centipedes are not insects but rather myriapods, thus supporting the claim that centipedes are distinct from insects.
The blog post from an entomologist 7 provides a more informal yet informative take on the classification issue. While it is written by a professional, the blog format may introduce some bias based on the author's perspective.
The Australian Museum 9 is a reputable source, providing scientifically accurate information about centipedes and their classification as myriapods rather than insects. This source is reliable due to its educational mission and expertise in biological sciences.
The Orkin pest control article 8 presents practical information about centipedes, but it is important to recognize that the company has a vested interest in pest control, which may influence how they present information about these creatures.

Overall, the evidence from multiple sources consistently indicates that centipedes are not classified as insects, but rather as myriapods within the broader arthropod phylum.

Conclusion

Verdict: False

The claim that centipedes are classified as insects is false. Key evidence supporting this conclusion includes the distinct taxonomic classification of centipedes within the class Chilopoda, which is separate from the class Insecta. Anatomical differences, such as the number of legs and body segmentation, further reinforce this classification. Additionally, reputable sources, including the National Park Service and the Australian Museum, consistently affirm that centipedes are myriapods, not insects.

It is important to note that while the evidence is robust, the classification of organisms can sometimes be subject to ongoing research and debate within the scientific community. However, the current consensus firmly places centipedes outside the insect classification.

Readers are encouraged to critically evaluate information and consult multiple sources when seeking to understand biological classifications or any scientific topic.
