Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'водяной жук' unless context is explicitly biological; in casual description, Russians might simply say 'жук в воде' (beetle in the water). The English term is a fixed compound.
Common Mistakes
- Using 'water bug' interchangeably (a water bug is a different order of insect, like a giant water bug).
- Capitalising it as a proper name (unless starting a sentence).
