Definition
Meaning
A family (Tachinidae) of true flies whose larvae are internal parasites of other insects, particularly caterpillars and beetles.
Refers to any fly within the Tachinidae family, often considered beneficial in agriculture and gardening as biological control agents against pest insects.
Linguistics
Semantic Notes
The term is primarily taxonomic, referring to the family as a whole rather than a specific species unless modified (e.g., 'the red-tailed tachina fly').

Examples
By Part of Speech
adjective
British English
- The tachinid parasite was effective.
- We studied tachinid host preferences.
American English
- A tachinid infestation weakened the gypsy moth population.

Examples
By CEFR Level
- Some flies in the garden are tachina flies.
- The tachina fly is a parasite.
- Gardeners often welcome tachina flies because their larvae consume pest caterpillars.
- The life cycle of the tachina fly involves finding a suitable insect host.
- The introduction of specific tachinid species has been proposed as a classical biological control strategy against the invasive spongy moth.
- Research indicates that tachina fly oviposition behaviour is influenced by host plant volatiles.
Learning
Memory Aids
Mnemonic
Imagine a taxi (tachi-) flying to a caterpillar to drop off parasitic passengers (its larvae).
Conceptual Metaphor
NATURE'S PARASITIC TAXI: The fly is conceptualised as a vehicle that delivers its young to a host.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation as 'тахина муха' which is not standard; the accepted Russian term is 'тахина' or 'тахинид' (takhina/takhinid).
Common Mistakes
- Misspelling as 'tachinid fly' (correct variant) or 'tachine fly'.
- Using as a common name for a single species without specification.
- Confusing with other parasitic flies like bot flies.

FAQ
Frequently Asked Questions
No, tachina flies are not parasitic to humans or vertebrates; they only target arthropods, primarily insects.
Planting a diversity of flowering plants can provide adult tachinids with nectar, encouraging them to stay and parasitise pest insects.
The name comes from the Greek 'tachinos', meaning 'swift', likely referring to their flight.
Yes, 'tachinid' is a shorter, equally correct term for a member of the family Tachinidae.
