ties the species migrates and breeds on culti- 
vated apple (Pyrus malus). A single Illinois 
specimen was collected on locust (Robinia 
pseudoacacia). Known as a pest of apple in 
New York where the nymphs have been 
observed to puncture the small fruits; this 
species is not, however, so serious a pest as 
Lygidea mendax Reuter.
