An up to 2.6 centimeters long Yellow-headed Spider-hunting Wasp, spotted in Chitwan National Park. The head, long antennae, legs, and front part of the thorax are yellow-orange, whereas the body is mainly black, and the eyes tawny-black. The wings are black with a metallic blue sheen.

As their name suggests, Spider Wasps hunt, capture and paralyze spiders. This specific species generally targets wandering spiders, which it  grabs, paralyzes and drags to its nest, i.e. a self-constructed burrow in the mud or sand.

There, the female wasp will bury the spider alive and lay a single egg on its abdomen. Then, it will close the burrow off and leave the spider as living food for the wasp's larva.

The Spider Wasp's nest has to be large enough, as the spiders it catches are often larger than the wasp itself.
