Description: The shape is similar to that of a snail but lighter, smaller, and capable of flight; originally lives in grass. In August and September, when it grows cold, they often enter human dwellings for shelter. There are two or three types, which can be consumed as food.
[Note]: This insect has a pungent, spicy taste and an odor. People in Hanzhong eat it, believing it directs Qi downward, calling it Shijiang (Stone Ginger), also known as Lu Chong, or Fupan.
*Bencao Jing Jiuyi* states: Its shape resembles a silkworm moth, with a red abdomen. It is harvested in February and August; this is what southerners call Huachong (Slippery Insect).

[Tubie (Ground Beetle / Eupolyphaga)]
Taste: Salty. Nature: Cold. Toxicity: Toxic.
Indications: Primarily treats chills and shivering in the heart and abdomen, blood accumulation, and fixed masses (Zheng Jia); breaks up hardness; promotes menstruation in cases of amenorrhea; greatly beneficial for fertility.
Aliases: Dibie, Tubie.
Habitat: Grows in the rivers, marshes, and sands of Hedong, and in damp soil under the walls of houses.
Harvest: Taken in October, dried in the sun.
Antidotes/Incompatibilities: Averse to Saponin (Zaojiao) and Acorus (Changpu).
Description: Flat in shape like a turtle, hence the name Tubie; possesses a shell but cannot fly; has a slight odor; currently found in many households.
[Note]: This creature prefers to live in soil around mouse burrows and under house walls. Its shape resembles a woodlouse (Shufu); the larger ones are over one cun long. The form is small like a turtle but lacks a hard shell, having only scales.

[Qicao (White Grub)]
Taste: Salty. Nature: Slightly Warm, Slightly Cold. Toxicity: Toxic.
Indications: Primarily treats bad blood, blood stasis with bi-syndrome Qi stagnation; breaks up blood clumps causing hardness, fullness, and pain in the hypochondrium; treats amenorrhea; treats ocular conditions such as pterygium, nebula, and leukoma. Treats hematemesis remaining in the chest and abdomen, fractures, blood clots, internal blockage from traumatic wounds (Jinchuang), postpartum cold invasion, and promotes lactation.
Aliases: Qi, Feiqi, Boqi.
Habitat: Grows in the flat marshes of Henei and in grassy areas where household manure accumulates.
Harvest: Can be taken at any time; those moving in reverse direction are considered superior.
Interactions: Guided by Feilian (Cockroach); incompatible with Fuzi (Prepared Aconite Root).
Description: The large ones are as big as a human thumb; they move by rolling on their backs, faster than walking feet. Mixed with pig trotters to make soup for nursing mothers, they are indistinguishable. The *Classic of Poetry* says "neck like a Qici" (white grub); this specimen can be distinguished. Since the character 'Qi' is placed lower in the name, it is suspected that "Qicao" here is inverted.
[Note]: This insect is found either in manure piles or in rotting wood. Those in rotting willow wood are white inside and out; those in soil/manure have yellow skin and dark black interiors. Since their colors and forms differ, and their substrates (wood vs. soil) vary, the ones from wood are considered superior. Although harvest time is flexible, winter collection is preferred. According to *Erya*: Also known as Xie, [missing character], and Youqi.
