Pheidole megacephala is a shiny bimorphic species with common small minor workers and more rare major workers with oversized heads. It is a very strong recruiter that forms tight foraging lines and can defend food resources. Notice in the videos how the minor workers are capable of taking large chunks of peanut butter from the bait which they carry back to their nest.
Notice the nest entrance is a very small unadorned hole in the soil towards the center right of the screen.
