💡 Everyday Comparisons for Size, Mass & Speed

💡 Its body length of 3 mm is one-eighth the diameter of a Korean 100-won coin (24 mm) (Comparison).
💡 A paper in the Korean Journal of Applied Entomology reports that adzuki beans fed on by this weevil (damaged seeds) had a 0% germination rate.

📖 1. Overview

The Chinese bean weevil is a small weevil in the subfamily Bruchinae that infests harvested adzuki beans as a stored-grain pest and is distributed worldwide.

🦴 2. Anatomy & Morphology

It is a small weevil 2–3 mm long with a broad rear end and a flattened back. Its back is usually reddish-brown with a white spot in the center of the pronotum, and the male has comb-shaped antennae.

🔍 3. Ecology & Behavior

It lives parasitically inside harvested adzuki beans. In a Korean study, it produced 4 generations a year at room temperature, overwintered as a larva inside seeds, preferred adzuki beans most, and took an average of 29 days to emerge from adzuki beans.

🇰🇷 4. Connection to Korea

It is listed as 'Pat-ba-gu-mi' (Korean name) on the National List of Species of Korea, and materials from the Rural Development Administration record its domestic distribution as nationwide.
