the.com/water strider

means A long-legged bug that skates across pond and stream surfaces, using surface tension and water-repellent legs instead of sinking or swimming.

from The name is simply descriptive English, built from 'water' plus 'strider' — one who strides. 'Stride' goes back to Old English 'strīdan', meaning to straddle or take long steps, related to old Germanic words for stretching the legs apart. No myth here, just plain compound naming: the bug strides, on water, so it's a water strider — though it's also called a pond skater or Jesus bug in different corners of the English-speaking world, that last nickname a wink at its famous ability to walk on water.
