Female flies in the family Bombyliidae fly close to the surface of the salt flat. When a tiger beetle larva attacks their shadow, the fly lands close to the tiger beetle larval burrow. The fly carefuly approaches the burrow and waits for the larva to retreat to the bottom. After the larva retreats into its burrow, the fly flips eggs into the burrow. The eggs hatch and the larva or larvae attach themselves to the tiger beetle. They feed very little, patiently waiting for the larva to pupate. When the tiger beetle begins pupation, the parasitoids rapidly consume the larva and emerge in a few days.
