machilid
Technical/ObscureHighly technical/scientific
Definition
Meaning
A wingless insect of the order Archaeognatha, commonly known as a bristletail.
A small, primitive, wingless insect characterised by its humpbacked appearance, three long tail filaments, and the ability to jump via a spring-like mechanism.
Linguistics
Semantic Notes
The term is used almost exclusively in entomology and paleontology. It refers specifically to a member of the family Machilidae, within the order Archaeognatha. Not to be confused with silverfish (order Zygentoma), which are different wingless insects.
Dialectal Variation
British vs American Usage
Differences

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "мокрица" (woodlouse) or "чешуйница" (silverfish). A direct translation does not exist; use the scientific term "махилида" or the descriptive "щетинкохвост" (bristletail).
Common Mistakes
- Pronouncing it as /ˈmætʃɪlɪd/ (like 'match'), incorrect pluralisation (machilids is correct), confusing it with silverfish.

FAQ
Frequently Asked Questions
No. While both are wingless insects, machilids (order Archaeognatha) have cylindrical bodies, can jump, and have compound eyes that meet on top of the head. Silverfish (order Zygentoma) have flatter bodies, cannot jump, and have widely separated eyes.
You would only realistically encounter this word in specialised scientific literature such as entomology textbooks, academic journals on insect evolution, or detailed field guides to invertebrates.
It is pronounced muh-KY-lid. The stress is on the second syllable, which rhymes with 'eye'.
No. Machilids are harmless detritivores, feeding on algae, lichens, and decaying plant matter. They are not pests and do not bite or sting humans.
