This family represents one of the smaller groups within the superfamily Vespoidea, classified only to two subfamilies. Members of both of them occur in the Palaearctic region, but only Scoliinae occur in the central Europe. Most of the species live in tropical and subtropical regions; all species occurring in central Europe have their northern distribution border in this region. Scoliidae are larger or large insects, usually colourful, hirsute and robust. Megascolia maculata (Drury, 1773) is the largest aculeate hymenopteran species in Europe and one of the largest in the world. Both males and females are winged, males are slenderer with long antennae, females’ antennae are shorter and clubbed. Except the main characters the following ones are typical for Scoliidae: distal parts of wings have length-wise wrinkles, mesosternum and metasternum are divided by a transverse suture, and basal segments of rear legs (hind coxae) are well-separated. Scoliidae are parasitoids of mature larvae of scarabaeid beetles; females search for larvae finding them by vibratory signals, paralyze the larva and lay eggs on its surface. Larvae feed usually in the ground on tissues of the scarabaeid larva. Imagines feed on nectar on flowers.

So far 3 species are known from the Czech Republic (2 from Bohemia, 3 from Moravia).
