In July, sabre wasps (Rhyssa persuasoria), which are distinguished by their size and unique black and white bodies, begin to emerge. The larger females, up to 40mm, are dwarfed by the tiny males, which are just 10–20mm. Their legs are crimson and their abdomens are elongated; they live mostly in wooded areas in Europe and Oceania. Longhorn beetles are the target of the reproductive cycle of the females of this parasitic species.
