Head of a parasitic wasp, SEM
Head of a parasitic wasp. Coloured scanning electron micrograph (SEM) of the head of a parasitic wasp (Aphelinus abdominalis). This tiny wasp is a parasite of potato and foxglove aphids. Its two compound eyes (green) are at right and left. At lower centre are the wasps mouth parts, with the antennae above them. A. abdominalis is a parasitoid, a parasite that always kills its host. Females lay their eggs in the aphids body and when the larvae hatch they feed on the aphid from the inside out. Adults also feed on the aphids, piecing holes in them and sucking out their bodily fluids. A. abdominalis is used as a biological control agent for aphids

EDITORS COMMENTS
This print showcases the intricate head of a parasitic wasp, captured using a scanning electron microscope (SEM). The vibrant colors bring to life the fascinating details of this tiny creature. Known as Aphelinus abdominalis, this particular wasp species is a natural enemy of potato and foxglove aphids. The compound eyes of this parasitic wasp are prominently displayed on either side, shining in an enchanting shade of green. Positioned at the lower center are its mouth parts, with delicate antennae gracefully arched above them. A. abdominalis is classified as a parasitoid, meaning it always kills its host for survival. Females lay their eggs inside aphids' bodies, and once hatched, the larvae consume their hosts from within. Even adult wasps contribute to controlling aphid populations by piercing holes in these pests and extracting their vital fluids. With its remarkable sensory capabilities and specialized jaw structure visible in this image, A. abdominalis exemplifies nature's ingenious mechanisms for biological control against harmful insects like aphids. This stunning photograph not only serves as a testament to the wonders found in our wildlife but also highlights how science can unravel hidden marvels through advanced imaging techniques like SEM.
