Argentine ant queen and worker. Because the queen
lacks wings, the ants occupy broad swaths of territory. Winged ants move
faster, and occupy less continuous areas.

A worldwide invader, 2 mm long, dark brown or
black in color. It probably reached the United States by ship from
Argentina in the 1980s, now spreading up the California coast. A
nuisance in kitchens, it also displaces native ants in California
and elsewhere. According to a new study, the ant is replacing larger,
native ants eaten by the horned lizard, a native species that's
on the decline.
Tip of the iceberg: The more destructive
fire ant has yet to reach California in large numbers. Fire ants
are highly destructive to all sorts of small critters in the Southeast,
not to mention Homo sapien var. picnicus.

want to meet-and-greet.
