I've found at least four or five species of ants on campus.

Today was my first time seeing myrmecophilic insects that live in ant nests.
Sadly the only ones I could photograph were springtails.
I found round-bodied, wingless crickets (5 cm long) living amongst these ants (another nest, though) but they escaped deep into the nest by the time I came back with my camera to the spot where I found them. (I foolishly tried digging for them but to no avail. Won't do that one again.)
