These two names are essentially the same. This occurs in maple species that fall into the “soft maple” family (VS Hard Maple). The appearance is actually caused by Ambrosia beetle that carries a fungus on its legs that causes the turquoise coloration. The holes are due to the beetle boring through the living wood.

It is a bit softer than its cousin Hard Maple. The sugar content is actually higher in soft maple than hard maple and that really makes tooling difficult when achieving a fine finish. 

In the guitar design arena, the discoloration and worm hole or beetle hole pattern is highly desired. Now, Ambrosia Maple guitar sets are beginning to sell for more money.
