Photo 2

a collection of amoeba, stained red

Individual amoebas aggregate, as shown here, to form what's called a "motile slug." How they interact to do this may help explain how biological social systems evolve.

a stained egg of the small parasitic wasp

In a stained egg of the small parasitic wasp, Trichogramma kaykai, are brightly staining Wolbachia. The bacteria accumulate at the end of the egg that is destined to develop into the reproductive organs. Wolbachia induce the eggs of this wasp to develop into female offspring without fertilization.
