Ammophila placida is a species of thread-waisted wasp in the family Sphecidae.

Most often Ammophila placida will fly low to the ground to transport the dirt, but rarely it may walk.

Ammophila placida has been observed to prey upon the caterpillars Noctuidae, hesperiidae, and geometridae.

Due to the firm soil it nests in, it must dig for the loose sand or dirt it requires to fill the hole.

It has been observed using small pebbles or pieces of wood to hammer and push the dirt into the hole.
