black bean aphids

don't know why these are called " black fly" as they don't have wings?

They have winged and wingless forms. This is info from the UK other countries will be slightly different

A generation of aphids survives the winter as eggs, which allows them to withstand extreme environmental conditions of temperature and moisture. In spring the eggs on the plant (primary host) hatch, leading to the first generation of aphids. All the aphids born from the winter eggs are females. Several more generations of female aphids are born during the spring and summer. A female can live for 25 days, during which time she can produce up to 80 new aphids. Spring and summer reproduction occurs asexually – without males. In these cases, the resulting aphids are basically clones of the mother. In addition, the young are born live rather than as eggs. When the fall approaches, there is a generation that grow into both male and female individuals. Females fertilized by the males lay winter eggs on the plant where they are, closing the cycle.

What a GREAT macro shot of those tiny aphids. I’ve seen groups of these on some plant stems in my own backyard but ours look more solid black.
