egg parasitoids

Just 0.5 mm, these wasps are rather small for light microscopy..... This SEM picture of the egg parasitoid Trichogramma evanescens on an egg of the Large White butterfly was made with Marcel Giesbers at the Wageningen EM centre. The black and white image was colored thereafter in photoshop. Below also a focus stacking picture with a macro camera. This species can parasitize and completely develop within the eggs of Lepidopterans. Their brain is just 200 micrometers in size but still these wasps can show a complete behavioral repertoire, see this link

Be patient, egg parasitoids are not very fast. You are watching an insect smaller than a millimeter, the parasitoid wasp Trissolcus basalis, the green vegetable bug parasitoid. It is parasitizing the eggs of, as its name already says, the green vegetable bug Nezara viridula
