water strider
LowTechnical, Formal, Educational
Definition
Meaning
A slender, predatory insect that skates on the surface of still or slow-moving water using its long, water-repellent legs.
Any insect of the family Gerridae; an insect adapted to move on the water's surface tension. By metaphor, can refer to anything or anyone that moves lightly and quickly across a surface.
Linguistics
Semantic Notes
Refers specifically to a family of insects (Gerridae). The term is literal and descriptive, not metaphorical in its primary use. It denotes a specific zoological entity.
Dialectal Variation
British vs American Usage
Differences
The term 'water strider' is standard in American English. In British English, 'pond skater' is the predominant common name. The scientific name 'gerrid' is used internationally.
Connotations
Both terms are purely descriptive and neutral. 'Pond skater' may sound slightly more colloquial to British ears.
Frequency
The term 'water strider' is very infrequent in general UK English, while 'pond skater' is the default. In the US, 'water strider' is the standard common name.

Learning
Memory Aids
Mnemonic
Think: It STRIDES across the WATER. A 'strider' is one who takes long steps.
Conceptual Metaphor
SURFACE IS SOLID GROUND (for the insect); EFFORTLESS MOVEMENT IS GLIDING.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as "водный шагоход". The established Russian term is "водомерка" (vodomerka).
Common Mistakes
- Misspelling as 'waterstrider' (should be two words or hyphenated: water-strider).
- Confusing it with a 'water boatman' or 'backswimmer', which are different aquatic insects.

FAQ
Frequently Asked Questions
No. A water strider is an insect (six legs). A water spider, like the diving bell spider, is an arachnid (eight legs) and often lives underwater in an air bubble.
Many species of water striders have wings and can fly to disperse to new bodies of water, while other populations may be wingless.
They are predators or scavengers, primarily feeding on small insects, like mosquitoes, that become trapped on the water's surface.
Their legs are covered in tiny, water-repellent hairs (microsetae) that trap air and exploit the water's surface tension, distributing their weight over a large area.
