A genus of considerable extent and universal distribution in 

 sufficiently warm regions. The British species belong to a group 

 whose larvae probably all feed on Compositae ; but some others 

 have the singular habit of feeding on the injurious species of 

 Coccus (scale-insects), and are thus beneficial.
