💡 Everyday Comparisons for Size, Mass & Speed
- 💡 In North American pine forests invaded by pine-damaging Sirex woodwasps, members of this group (Rhyssa species) are found together with them as natural enemies (PMC paper).
- 💡 It detects unseen larvae inside wood by the smell of fungus and lays eggs using its long ovipositor (UCR Ichneumonidae resource; PMC paper).

📖 1. Overview
The sabre wasp (Rhyssa persuasoria) is a parasitoid wasp in the tribe Rhyssini (family Ichneumonidae) that parasitizes large horntail larvae boring inside wood.
🦴 2. Anatomy & Morphology
Wasps of the genera Rhyssa and Megarhyssa stand out for their ovipositors, which are longer than their bodies.
🔍 3. Ecology & Behavior
It is an ectoparasitoid on full-grown horntail larvae inside wood. According to research, it locates its host using the scent of fungus growing on frass near the larva as a cue (Spradbery, 1970).
🇰🇷 4. Connection to Korea
It is listed as 'Song-got-beol-sal-i-nap-jak-maep-si-beol' (Korean name) on the National List of Species of Korea.
