It has been too long, so let's jump back in.
I would have probably not noticed these ants if an observant three-year-old girl hadn't pointed them out.
Sidewalk ants (Forelius) are fairly small, after all. Plus, only a few ants were active on such a chilly day.
These ants are benefiting from the discarded lollipop stick left by another child.
Thank you, Rosie.
