Preparing and photographing a mosquito's heart is an incredibly exacting job. A slit has to be cut into the bug's abdomen. Its stomach and other organs have to be removed. Two types of stain have to be applied to the heart and its surroundings: fluorescent green phalloidin for the muscles, and blue Hoechst stain that binds to the DNA in cell nuclei. Then the specimen is put under a microscope, and filtered light zeroes in on the stained cells.
