They are found mainly in the United Kingdom, the Czech Republic, France, Germany, Greece, Italy, Spain, Portugal, Switzerland, in western Asia and northern Africa.

C. lucasina can be distinguished from other members of the carnea-group of the genus Chrysoperla by subtle and variable morphological attributes.

They are polyphagous, feeding on pollen and nectar of various herbaceous flowering plants (mainly Brassicaceae, Graminaceae, Apiaceae, and Asteraceae), as well as on honeydew, their preferred diet in Autumn.

After the feeding period, they fly near colonies of aphids, where they breed and the females lay eggs.

Unlike the adults, the larvae are fearsome predators; consequently, these insects are used for the biological pest control of aphids and other small arthropods.
