Insect microscopy. 19th century artwork showing microscopic details of insects, as seen under a microscope. An aphid is seen at top centre, with a tsetse fly proboscis immediately below it. Below and left of the proboscis is a feathery type of antennae, as often seen on moths. Claws, as seen on an insect's foot, are seen below the feathery antenna and at right of the proboscis. Other items seen include insect larvae and eggs. Artwork taken from the 1883 edition of Jabez Hogg's book The Microscope: its History, Construction and Application.
