A really useful blog post (not mine)

Photos of L. humile and some other species by Alex Wild

Alex Wild over at Myrmecos has just posted a really useful post on how to identify the Argentine ant, Linepithema humile. I wish I'd had this post back when I was identifying all my samples. I cannot explain to you how long I agonized over whether I even had Linepithema, let alone which species they were. This is such a nice explanation that I may even be motivated to go back and look at some of those specimens again. Ack!
