Deraeocoris lutescens is a Mediterranean species, distributed also in small numbers in Central Europe. Known mainly as an egg predator of pear psyllid Cacopsylla pyrisuga and hawthorn psyllid Cacopsylla crataegi ( Herard 1986). It is also reported as a predator of aphids and mite Panonychus ulmi in apple orchards in Croatia ( Arčanin and Balarin 1972) and in pear orchards as a predator of Cacopsylla pyrisuga in France and Turkey ( Herard 1986, Erler 2004).

Deraeocoris lutescens has been already registered in Serbia ( Protić 1993) but here is reported for the first time as a predator of psyllids in this country.
