Etymology
蛍 is a phono-semantic compound: 虫 (insect) gives the meaning, and the top part (⺌ over 冖) likely contributes the sound ケイ. The character originally referred to a firefly.
Meaning mnemonic
The bottom 虫 is an insect, and the top ⺌ over 冖 looks like a little glowing light with a cover. Imagine a tiny insect carrying a lantern: that's a firefly.
Reading mnemonic
For ケイ, picture a firefly glowing like a tiny letter K in the dark: K -> ケイ, and the firefly's light spells out its reading.
