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.


  1. Very cool! I love the transparent pink and gold colors.

  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.

  3. hello. i'm want to ask....where is the specific location of the salivary gland of the midges larvae(1st picture above) and how does it looks like?
