Common Green Lacewing, Aphid Lion
Common Green Lacewing is a common garden insect and one of the only lacewings that hibernate. They're a pale green colour and have delicately-looking, transparent wings. They're highly effective predators, giving them their alternate name the 'aphid lion'.

Biological treatment
By introducing other bugs to the plants that are effected you can cut down the damage that lacewing cause by reducing their numbers. Insects such as spiders and wasps will feed off of the lacewings.
Chemical treatment
Insecticides can be used to kill both larvae and adult Chrysoperla carnea. Using flonicamid, sulfoxaflor and flupyradifurone based ones are the best resulting.
