The lerp-scales were very numerous upon the foliage of saplings 

 or shoots springing up where trees of swamp mahogany (E. 

 robusta) had been cut down near Manly in the summer of 1892, 

 but have never appeared there since. The extraction of the sap 

 by the larva? in feeding and in constructing their beautiful scales 

 causes a large brown blotch to appear wherever one was formed, 

 and it was the curious spotted appearance of the foliage so caused 

 that first attracted notice.
