When the rubytail wasplarvae have hatched, they (after having scoured the aisles of the nest of food competitors) feed on the eggs or larvae of their hosts. Rubytail wasp larvae always hatch before their host’s larvae. Approximately 14 days after the rubytail wasp larvae hatch, even the food supplies of their hosts (only insects, no pollen) have been consumed, and they spin a cocoon for themselves in the host’s nest and pupate, either immediately, and then either to fly as another summer generation in th...
...ey spin a cocoon for themselves in the host’s nest and pupate, either immediately, and then either to fly as another summer generation in the same year, or to overwinter inside of the cocoon. This assumes that the host larvae overwinter as well. The rubytail wasp is able to synchronize its development with the annual cycle of the various host larvae. | | |

The host insects try to prevent the rubytail wasps from entering their nests, however the latter are not only equipped with a strong chitin-armoured surface, but are also able to roll their bodies and thus significantly can reduce their body surface.

...quipped with a strong chitin-armoured surface, but are also able to roll their bodies and thus significantly can reduce their body surface. This protects them against bites and helps them to penetrate the narrow passages of the host nests. Thus, the rubytail wasp remains largely intact, with the exception of the wings, which sometimes get damaged. | | |
| | Adult rubytail wasps reach body lengths of 4 - 13 mm. Their size depends on the conditions of development? environmental conditions present during the larval stages. Their bodies are slim and vary in shape. The head and chest (thorax) are bright blue-green in colo... | | |
| | Rubytail wasps prefer sunny, dry habitats up to high altitudes. They can be found from May to September on warm stone walls, wooden walls, telegraph poles and fences. The adults live off nectar from plants of the parsley family (Umbelliferae). | | |
