Description
''Rhyssa persuasoria'' (specific epithet meaning ''persuasive burglar'') is one of the largest ichneumon wasps in Europe. The length of adults varies from about in males up to in the females, plus about of the ovipositor. These ichneumon wasps have a thin black body, several whitish spots on the head, thorax, and abdomen and reddish legs. The antennae are long and thin. Females have a long ovipositor, which they use when laying eggs. The length of the ovipositor exceeds the body length.[Nature Spot]

This species is rather similar to '' Rhyssa amoena'' Gravenhorst, 1829.
Biology
Adults can mainly be encountered from July through August,[ especially in paths and clearings of coniferous forests. They feed on carbohydrates such as sugar and starch, which are obtained, for example, by feasting on honeydew or pine needles. Flowers are not visited.
Female of this parasitic species drills deep into wood by its hair thin ovipositor (terebra) and lays its eggs on larvae living deep in timber (up to 40 mm), which become a food supply and an incubator for the progeny, until it is fully grown. This species has one generation a year ( univoltine). Larvae overwinter in the wood, pupating the next spring and emerging from the wood as adults.
Main hosts of ''Rhyssa persuasoria'' are the larvae of horntails or wood wasps ('' Urocerus gigas'', Siricidae species, a type of ]xylophagous
