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.
After mating, the fertilized females lay their eggs in the nests of different bee and waspspecies, for example Heriades truncorum and Ancistrocerustrifasciatus. Occasionally, oviposition takes place in butterfly cocoons, as observed in the case of the small tortoiseshell (Nymphalis urticae). Usually one egg is placed in each nest. Egg-laying often takes place in the nests of solitary bees of the genera Hylaeus and Osmia. A few days later the larvae hatch from their eggs. Firstly they eat the eggs or larvae of the host animals and later on any food supplies found there.
