Leishmania mexicana is a protist that causes disease in humans by infecting and living within our immune cells. This panels shows its lifecycle in the insect vector.

An over-expressed GFP-protein fusion is sorted to the lysosome for recycling, making this organelle fluoresce green. Hence we can follow the behaviour of this organelle, that has a curious tubular morphology, through cell division in the insect stage (promastigote).
