About 2 weeks later (in July and August), the adults of the 2nd cherry slug generation hatch, mate and lay eggs. The larvae (cherry slugs) are active from September to October. They also pupate and overwinter in the soil. They leave the pupae as adult cherry slugs in the spring. | | |

| Gasteruption jaculator are active during the day from May to September, and are found in a variety of habitats, including forest edges, shrubbery, hedgerows, meadows, gardens and natural parks. It is particularly fond of the parsley family, where it feeds on pollen, nectar or honeydew. | | |

The larvae have now reached body lengths of 90 - 100 mm and pupate in the period from July to August in tunnels, which are about 80 mm deep. The pupal period lasts 4 - 6 weeks. In late September or early October of the 4th year, up to 200 great capricorn beetles hatch in a single tree. The entire development period of the larvae can be up to 5 years. | | |
