Trigonalidae
Trigonalidae is a family of parasitic wasps constituting the sole living members of the superfamily Trigonaloidea. With over 90 described species in 16 genera, these wasps exhibit a remarkably complex life history involving hyperparasitism. Females deposit thousands of minute eggs on or within leaves, which must be consumed by a caterpillar to initiate development. The family is divided into two subfamilies: Orthogonalinae (containing only Orthogonalys) and Trigonalinae. Trigonalidae has been proposed as the sister group to all Aculeata.
