Aphids are strange pests. The insect feeds on plants... and their colonization on leaves and stems spells disaster for vegetation. And while they are not the most welcome insect in gardens... I do find them interesting to photograph. Their strange dancing habits are bizarre; all insects on a plant sit still for a minute, then simultaneously raise themselves up as if doing hand-stands.
