How to Write 蟭 (jiāo) — Meaning “Mantis egg case”

Imagine a mantis egg case that looks like a tiny insect (虫) that has been "charred" or "burned" (焦) because it is often attached to dry twigs. The pronunciation "jiāo" sounds like "jiao" as in "jiaozi" (dumpling) — picture a dumpling-shaped egg case.

The left radical 虫 should be narrow, about one-third of the character's width, with its dot centered. The right part 焦 has a complex structure: write the top 隹 (bird) with seven strokes, then add 灬 (fire) below, making sure the four dots are evenly spaced and not too large.

Visually, 蟭 has 焦 on the right, while 螃 has 旁 (páng) and 螅 has 息 (xī). Their meanings are completely different: 蟭 means "mantis egg case," 螃 means "crab," and 螅 means "intestinal worm." They also have different pronunciations and are used in entirely separate contexts.

蟭 is extremely rare in modern Chinese and not part of the HSK vocabulary. It appears mainly in classical literature or biological texts referring to the mantis egg case, which is more commonly called 螵蛸 (piāo xiāo). Because of its obscurity, you will almost never encounter 蟭 in daily conversation.

Common words containing 蟭 include: 蟭螟 (jiāo míng) — microscopic insect; 蟭蟟 (jiāo liáo) — cicada; 蟭螟翼 (jiāo míng yì) — wing of a microscopic insect.
