Abstract

Adult braconid wasps (Bracon sp.) emerged from the droppings of frugivorous birds (Turdus blackbirds and thrushes) collected in a rural environment in southern Europe. It was thus demonstrated for the first time that an insect parasitoid of a fruit-infesting insect (lepidopteran tortricid) can survive bird ingestion and gut passage inside a seed (privet Ligustrum vulgare), constituting a case of an evolutionary tetrad.
