Cryptocheilus bicolor (orange spider wasp) is a large, strikingly coloured spider wasp from Australia.

The prey is then dragged to a burrow, dug by the female using shovel-like hairs on its front legs.

The wasp then lays an egg on the spider, and conceals the nesting chamber at the end of the burrow.

When the grub hatches it feeds on the spider before pupating[1] in a thin silky cocoon in the cell.

[2] The wasp's sting has been described as extremely painful and "shockingly powerful".
