This highly colored insect is very common wherever it 

 occurs, and exhibits a tendency to congregate upon certain 

 plants in such numbers as to completely cover them. The 

 black saltonas with their bright markings of rose color and 

 white render them very consjjicuous objects. Notwithstand- 

 ing this they seem to be let alone by most insectivorous birds,
