After thinking about silly Mark Trail comic strips much more than I should, I thought I'd ask this forum about red imported fire ants (Solenopsis invicta). Fire ants originally came from South America, and they became a common pest in the United States. However, in our history, it took until the 1930s for the ants to begin their invasion of the southern U.S., and they spread to other countries such as Australia in later decades.

Could fire ant queens terrorize the world in an age of slow sea travel? If so, how far could they expand beyond their native habitats in the Amazon? Remember that fire ants can float on water in a sort of "raft" during floods.
