Wings of lace
I was very pleased to see this green lacewing on the coneflowers while I was photographing honey bees. Lacewings are a beneficial insect in a garden and as beautiful as any flower! This one was, most likely, feeding from the nectar of the flower along with the honey bees. It is the larvae of the lacewing that eats up soft-bodied insects such as aphids and caterpillars in the garden. They will, also, eat the larvae of other insects. To attract lacewings, you might want to plant (or allow to grow) flowers in the Asteraceae family such as sunflowers, dandelion, and cosmos and the Apiaceae family such as dill and angelica.
