Panzhihua Sand-Crawling Worms

　　Panzhihua Sand-Crawling Worms are a famous local specialty of Panzhihua City in Sichuan Province. Produced along the Anning River, they are commonly known as the “Anning ginseng” and scientifically named the Chinese large moth larva. These worms are warm in nature and sweet in flavor, tonifying qi and kidney function. Particularly valued for their nourishing, strengthening, anti-deficiency, anti-urinary incontinence, and foundational health benefits, they are considered an excellent ingredient for medicinal cuisine. Whether fried or steamed, they offer delicious taste and fresh juices.

　　The sand-crawling worm, scientifically named the Chinese large moth larva, belongs to the phylum Arthropoda, class Insecta, and order Lepidoptera. Commonly known as the “Anning ginseng,” it is produced in the arid-hot river valley of the Anning River, a tributary of the Yalong River, where Panzhihua City is abundant. The Chinese large moth larva prefers to hide in dark places during the day and becomes active at night. During the breeding period, adults lay eggs in the crevices of pebbles near the riverbank. Under suitable humidity and temperature conditions (which the arid-hot river valleys of the Panxi region uniquely provide), the eggs hatch into what we commonly refer to as sand-crawling worms. These creatures are typically 6 to 9 centimeters in length, dark green or deep brown in color, with small heads, numerous legs, and flat mouths. Their appearance is ugly and ferocious—so much so that just looking at them can be off-putting, not to mention eating them. However, one should not judge this insect by its looks. The locals by the Anning River have long used it to “nourish when raw and strengthen when cooked,” and it has proven miraculously effective in treating symptoms such as frequent nighttime urination in the elderly and bedwetting in children.
