Description

Workers small, brown, similar size to Linepithema humile but slightly smaller [say 2.25mm to 2.5mm]; major workers have disproportionally large heads. The ants I have found are browner than those in my sketch. Discovered 30 minutes ago the presence of these girls in my yard. It's a shocking discovery because we have always only had Argentine ants (Linepithema humile) in the garden. Some years ago the Argentines were driven out of the house by Technomyrmex pallipes - are they now losing ground in the garden too? What's going on here? And why are the Argies losing ground to a new set of invaders? Four blocks down the road they only have Lepisiota capensis! Weird stuff.
