Live from the Hawaii Ant Lab news desk… Little Fire Ants have a new name!
Recent research has determined that the scientific name for Little Fire Ants (LFA) is changing from Wasmannia auropunctata to Allomerus auropunctatus.
Why the change? New genetic research found that Allomerus and Wasmannia ants are actually more closely related than scientists previously thought, meaning they belong in the same genus. Since Allomerus is the older name, it takes priority.
For homeowners, nothing changes. Allomerus auropunctatus is the same tiny, stinging ant you know as LFA, and your treatment methods remain the same. But if you work with invasive ants or come across the new name in scientific literature or ant databases, you’ll know that it’s still referring to LFA!
