Not Evaluated (NE) on the IUCN Red List yet.
💡 Everyday Comparisons for Size, Mass & Speed
- 💡 A queen at 25–30 mm is similar to the diameter of a Korean 500-won coin (26.5 mm), and workers at 20–27 mm are equal to or slightly smaller than it (Comparison).
- 💡 Materials from the City of Nagoya note that because it often builds nests close to homes, such as in garden trees or parks, it accounts for many sting incidents.
- 💡 In the 2018 hornet trap survey at 27 children's parks in Cheonan, Chungcheongnam-do, the yellow-vented hornet was caught most frequently, showing it to be one of the hornets most commonly encountered in urban parks.

📖 1. Overview
The yellow-vented hornet is an insect in the family Vespidae (order Hymenoptera), called Kogatasuzumebachi in Japan. Materials from the City of Nagoya describe it as smaller than the northern giant hornet (queen about 45 mm) and relatively mild-tempered.
🦴 2. Anatomy & Morphology
Queens have a body length of 25–30 mm and workers 20–27 mm. The head is orangish-yellow, the thorax and abdomen are black, and there is a yellow band along the rear margin of each abdominal segment.
🔍 3. Ecology & Behavior
From early May it begins building nests in leafy branches and hunts various insects and spiders to feed its larvae. Worker numbers reach about 100 at the colony's peak.
🇰🇷 4. Connection to Korea
It is listed as 'Jommalbeol' (Korean name, Vespa analis Fabricius, 1775) in the National List of Species of Korea. In a 2018 hornet trap survey across 27 children's parks in Cheonan, the yellow-vented hornet was the most numerous, accounting for 290 (35.4%) of the 818 Vespa hornets caught.
