What 蝣 means
It means “mayfly,” usually inside 蜉蝣. Alone 蝣 is bookish shorthand; the full word names the short-lived insect and its brief-life image from the pre-Qin Book of Odes poem 《蜉蝣》.
See 虫 on the left for insect plus 斿 for sound, a relative of 游 and 遊. That shared sound part explains the resemblance; it adds no travel sense here.
In Japanese 蝣 also lives inside 蜉蝣, while literary Chinese keeps 蝣羽 for glossy, fine clothing borrowed from mayfly wings.
Bookish alone; use 蜉蝣 when the mayfly must be immediately clear.
Use the full compound when the insect must be understood.

1Why does 蝣 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
