Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'песчаная муха' (sand fly) for the common housefly. It is a specific insect. The more precise term is 'москит' (mosquito), but Russian 'москит' specifically refers to the sandfly/Phlebotomus, not the common mosquito ('комар').
Common Mistakes
- Spelling as two words: 'sand fly'. (Standard is one word: 'sandfly').
- Confusing it with a common housefly or fruit fly.

FAQ
Frequently Asked Questions
No. They are different insects. Sandflies are generally smaller, have a different flight pattern (hopping), and some species transmit different diseases (e.g., leishmaniasis vs. malaria).
They are very small (1-3 mm), often called 'no-see-ums' in the US, because they are hard to see until they bite.
They are found worldwide, but often in tropical and subtropical regions, and in sandy or moist habitats near coasts, rivers, or forests.
Use fine-mesh insect nets, wear long sleeves and trousers at dawn/dusk, and apply insect repellents containing DEET or picaridin.
