Entypus unifasciatus is a species of spider wasp in the family Pompilidae.

[1] Theses spider wasps are black with a bluish sheen, yellow antennae, and wings ranging from mostly orange to mostly black with an orange band near the apex.

[1] Female wasps paralyze large spiders and deposit them in burrows.

The wasp lays a fertilized egg upon the spider; after hatching, the larva feeds on the living but paralyzed spider until maturing into a pupa that overwinters, and emerges as a winged adult next summer.
