How to Write 蚧 (jiè) — Meaning “scale insect”

Imagine a small insect (虫) wearing a shell or a "scale" armor, and that armor looks like a flat shield (介). The word "介" can also remind you of "介壳" (shell), so picture a bug covered in a hard scale. This connects the left insect radical to the right shell component, making it easy to recall the meaning "scale insect."

The left radical 虫 must be written narrow and tall, with the third stroke (a horizontal line) slightly rising, and the final dot placed neatly on the right side. The right part 介 consists of a person-like shape (人) on top and two strokes below; avoid making the upper part too wide, as it should fit within the same height as the left radical. A common mistake is to make the right component too large, which makes the character unbalanced.

蚧 specifically refers to scale insects or the Tokay gecko, while 虮 (jǐ) means the egg of a louse or a tiny insect attached to hair, and 虰 (dīng) usually refers to a kind of insect or a person's name. Visually, 蚧 has the component 介 on the right, 虮 has 几 (jǐ), and 虰 has 丁 (dīng); these different right parts change both the pronunciation and meaning. So 蚧 is about "scale" or "shell" insects, while the other two relate to other small bugs.

蚧 is not a common standalone character; it appears mainly in the compound word 蛤蚧 (gé jiè), which means Tokay gecko, a lizard used in traditional Chinese medicine. It is also used in the term 蚧壳虫 (jiè ké chóng), referring to scale insects that harm plants. Culturally, 蛤蚧酒 (gé jiè jiǔ) is a wine made from Tokay geckos and is believed to have health benefits in Chinese folk medicine.

Common words containing 蚧 include: 蛤蚧 (gé jiè) — Tokay gecko; 蚧壳虫 (jiè ké chóng) — scale insect; 蛤蚧酒 (gé jiè jiǔ) — Tokay gecko wine.
