into caterpillars about two inches long, sprinkled 

 with gray, with numerous red-marked, branched 

 spines. They then leave the trees and in some 

 protected place transform into the chrysalis stage 

 from which the adult butterflies emerge in about

Pulvinaria innumerahilis — Cottony Maple 

 Scale — attacks the Maple-Tree and may be recog- 

 nized by the soft brown scale and cottony mass 

 which projects from it. The cottony mass is 

 really a wax or glue, in which are embedded 

 innumerable minute eggs from which the larvae 

 hatch and scatter in all directions. They insert 

 their sucking tubes into the leaf or twig and 

 begin the formation of a scale. They are some- 

 times very destructive.
