Ant Love From an Ant Nerd

A few weeks ago, this ant nerd traveled to the wilds of Arizona to pick up two ant colonies. Yes, myself and Leslie Gordon (the Museum's live animal queen), drove over 1000 miles in under two days to bring a few hundred ants back to the Museum. Why?

The ants I found are Argentine Ants, Linepithema humile. They are an introduced species from South America (Argentina and Brazil) and are now considered the most common ant in our area. According to the Insects of the Los Angeles Basin book, these ants were "introduced to New Orleans before 1891 in coffee shipments from Brazil, and it has since spread rapidly over much of the United States."
