Inner Mysteries of a Midge Larva


Small aquatic organisms - like this midge larva that came from the water butt outside my greenhouse - are conveniently transparent, so you can watch the internals workings of their bodies with amazing clarity under the microscope. The short video clip here shows a wave of muscular contraction driving food through this insect larva's gut.

  2. Hi Wilma, I think the pink pigment is haemoglobin, as in human blood - the larva came from pretty stagnant water so probably had high levels of haemoglobin for absorbing oxygen.
