mantis
螂 refers specifically to a mantis, an insect known for its folded, prayer-like front legs.
螂 is a phono-semantic compound: the insect radical 虫 indicates the meaning 'insect', while 郎 (ロウ) provides the sound. The character was created specifically for the mantis.
The left side 虫 shows it's an insect, and the right side 郎 looks like a nobleman with a tall hat. Picture a mantis standing upright like a praying nobleman.
For ロウ, imagine a mantis rowing a tiny boat with its folded arms: row -> ロウ, and the mantis rows like a nobleman.
