THE RHODODENDRON BUG. 



(Leptobyrsa (Steijhunitis) rhododendri, Horv.) 



The Ehododendron Bug is not a native of Great Britain and 

 was first observed in this country in 1910, but it had probably 

 been introduced some years earher. It is now distributed 

 throughout the rhododendron-growing districts of the southern 

 and south-western counties and occurs in East Angha. Although 

 the country of origin is not definitely known the bug is present 

 in many parts of the United States of America and it seems likely 

 that it is a native of the Eastern States of North America, from 

 which it has been distributed to Europe in the course of the 

 trade in living plants. 



The Ehododendron Bug is also known as the Ehododendron 

 Fly and the Lace Fly, but the two last terms should be avoided, 

 (1) because the insect is not a fly, and (2) because the true Lace 

 Wing* is a most useful insect and so not to be confused with 

 such a pest as is here described. 



Plants Attacked and Nature of Damage. — The Ehododendron 

 Bug is found upon rhododendrons and in the United States on 

 species of KaJmia, the newer rhododendron hybrids being far 

 more susceptible to damage than the long-established Rhodo- 

 dendron ponticum. The obvious signs of injury are the presence 

 of chocolate -brown spots on the underside of the leaf and a pale
