Fig. 2. Sporozoite transport through the hemolymph in mosquito wing veins. Arrows show the progress of a sporozoite (green) floating passively through a peripheral vein (upper images, 0–2 s) and subsequently through a larger central vein (bottom images, 2.64–4.64 s). Asterisks indicate a sporozoite apparently caught in a wing vein constriction. The number at the lower left in each frame is the time (s) at which the image was recorded. Scale bar, 100 µm.
