“Lady Bugs” or “Lady Birds.” 
This is one of the most important families of beetles. Many 
of the species in the larval form feed on plant lice and scale insects. 
Their value in ridding, vegetation of these pests can hardly be 
estimated. 
Introduced pests can sometimes be controlled by introducing 
their “Lady bug” parasite. The family is large and all, with few 
exceptions, feed on other insects. The rapidity with which Adalia 
and Brachyacantha will destroy a colony of “plant lice” (aphidac) 
is surprising. Our species are:
