DENDROBIUM BEETLE ( Xyleborus perforans). A 
destructive insect from the tropics, but Homeahing in 
Orchid-honses, where it is especially partial to Dendrobium 
Phalenopsis. Both Beetle and grub are destructive. The 
perfect imsect (Fig. 338) is rather more than ain. in 
length and of a chestnut-brown colour. As the specific 
name suggests, it perforates the stems (Fig. 339), and, once 
inside, tunnels in various directions, causing the plant

attacked to have an unhealthy look. The grub (Fig. 339) 
is white and footless. Plants showing signs of decay, and 
whose stems are found to be perforated in the way shown 
in the portion of plant illustrated, should 
have such portions removed and burned. 
The check received will be nothing to 
the damage that would ultimately occur 
were the insects allowed free play. In 
bad attacks Dendrobiums are sometimes 
killed. This Beetle does not feed ex- 
clusively upon Orchids: in the sugar- 
growing countries it is destructive to the 
canes.
